iis that toughbook really running xp?? wow get in touch with picoscope and see if there are issues upgradeing the os win 10 minimum is cpu 1ghz ram 1 gb so if ya got it and there software runs on 10 upgrade!!! better yet install linux install wine and run it in that for any company to send you that os to run there product would be almost equivalent to you installing an engine management system thats no longer supported by there manufacturer never mind the unfix able un modifiable design flaws
@@WatchWesWork wow there software is using an old style lol looks like xp lenovo...=thinkpad ibm should be a solid enough machine but no gameing on it but thats not what your useing it for so all good thanks for the reply and the vids
As a paramedic ... Here's what you can always assume with a used Ambulance: It's been run overweight, cold started, pulled out of the ditch at least twice (sideways, with the wrong equipment), run low on oil, run high on oil, driven with park brake on, slammed into park or reverse while still moving and it's been peed on. What happens on the second week, well that depends on the crew.
How an ambulance can be overweight? When the ambulance company put the body and all of the equipment on the chassis, the total weight must be under the maximum weight. The weight of crew, supplies and patient should be minimum compared to the ambulance weight.
Older does not necessarily mean better. Speedometer cables seized often, and there are distinct advantages to this configuration. It just requires a different skill set to work with it.
@@horacerumpole6912 I think both of them went "clink". Just lovely to hear when you are wrestling with a heavy, tight fitting piece in a cramped space.
Excellent job of diagnostics on that truck. Working on an ex-ambulance would scare most people from all of the systems that had been compromised during the build and "un-build" of the unit. Great job of capturing the information on video. Thanks for your work.
As a senior master Ford technician, I am impressed by your professional work ethics and knowledge. You were able to prove your diagnosis by skilled use of tools and continued to repair the truck until it was perfect. Most techs would have been satisfied after the previous repair when most of the oscillations were gone. Well done. It’s a pleasure to watch you work.
Getting to the bottom of this truck, was pretty remarkable. Not many people would have gone into this much detail to confirm the exact cause. Shops would have just thrown parts and shipped it. This job reminded me of my uncle, no matter the issue in a lost cause machine he always fixed it. It's rare to find a mechanic of this skill. Usually rare mechanics are self taught from the regular guy..Well done Wes.👍 Hope family is well.
Success. If the sensor relies on magnetic feedback from the teeth passing in front of it, it makes sense that density and shape variations would impact the reading.
Its goes to show you cant let a truck sit for yrs & expect nothing to go wrong, i drive a newer ford van & always fixing small stuff, before they get to big problems.
@@WatchWesWork yea, what Ralph said, one of my favorite scenes from the movie Christmas story. The puckering while removing the carrier was shared with me and others. When you were installing the carrier and I heard the ting-a-ling, nearly on cue we said the same thing lol
Hey Wes: And the person with F-150, 5.4L.Maybe they are going to work on the brakes. And I got a feeling he is going to sell that truck quick. To some poor soul.
An intelligent repair, based on diligent diagnosis... Great work Wes. Bet you have been looking around for suitable candidates to develop your PicoScope skills? Great vlog, and another happy customer 😊. Thanks for sharing and best regards John.
Makes sense why the amplitude was bouncing at a specific speed because the magnetic Field would be different at that speed then other speeds good Repair @Watch Wes Work
Hey Wes- Why did you quit "field mechanic" work? (or you still do calls?) You've mentioned before, you used to do other work? As what? How did you get to be where you are now? Is there a video explaining all of this? Thank you.
Problems you can't duplicate . . . are THE WORST. 🤬 But like some of my smarter mechanic friends say, I can't troubleshoot and fix what I don't see broken. 🤷🏻♂️
I've got to say, I worked twenty-five years at a Ford dealership, and I've never seen a tone ring go bad in a rear differential. I've replaced them when replacing a ring and pinion, but never by itself.
Great fix... Rust has extremely weak magnetic properties compared with steel, hence the bigger than expected variation in output from the passive sensor compared with what appears to be a small amount of surface rust / pitting on the tone ring. Good luck with the other gremlins :)
It's back lol if I didn't know any better I think you were working on my vehicles odd ball weird problems I give you credit you are more patient than I am keep up the good work
Talk about dogged determination. Yours is being put to the test with the F-350 ex-ambulance. As for your customer/neighbor with the F-150....kinda feel sorry for him. Obvious that he got screwed. Such a shame he didn't have you or some other qualified mechanic check it out first. It would have been a service charge well spent. Damn shame.
Outstanding. Love that axle pan I can remember draining everything and put all over the floor, soaking up rags. That's a product of necessity somebody invented.
To quiet those phasers use 5w40 oil my buddy from work had one of those and changed the phasers chains guides tensioner and oil pump the oiling system doesn’t supply enough oil to the top end the thicker oil help carry oil pressure up to those phasers and cam bearings
Hi Wes 👋 You have one of the best channels, you are so informative. Just wish you'd post more videos. I know they must be a pain in the ass to film. Keep up the great work. 👍
I know this is a Dana 70 BUT Sterling (Ford) 10.25 and 10.5" rear axles REALLY tend to leak out of the pinion splines. I put RTV on the splines as well as the washer. If it's a REAL LEAKER it only lasts about a year and you have to do it again, but it's not a hard maintenance item. NOT something you can do for a customer though. I also use RTV as an axle cap gasket as well. Never had one leak, or leak out of the bolt holes either. The U bolt style yoke is stronger than the strap style. HOWEVER, you can over torque them and distort the U joint caps.
Excellent diagnostics Wes, multiple issues, multiple problems and you got to have a fun time sorting it all out :-). If you ever want to get out of a rust belt area, Eastern Washington State is about as dry as a high desert climate can get (humidity wise). We don't have that problem on this side of the mountains. West side? Different story (coastal hive-cities with the accompanying, proud to be ignorant mindset) , still nothing like what you have to deal with. We don't salt roads. If you can get past the commie Governor and his commie AG, it's a nice state, or will be as soon as we get rid of the Clown Donkey and his cadre. You would be astonished at the "no rust" issues. I have a '92 Ford F-250. It has a very light patina of rust in places. You could be livin' the dream and I could have an excellent technician to take my stuff to. :-)
Looking at the axle shafts they are 1/2 the size of the ones I put back in our 1947 Greyhound bus yesterday. The probes come with the ASE Wave kit. I pulled a 2000 F250 trans that quit pulling all of the sudden and it was case damage under the valve body from a previous rebuild where they tried to pry the front pump. When the 1/2 moon chunk popped out from the fracture it lost the pressure to the forward clutches but reverse worked fine. Crazy stuff we run across!!!
I like the J.C. Smith style lift. Do you ever do pre-purchase inspections? How many of the F150 issues do you think you would found if you went to look at the truck with the customer? (Not on a lift.) Thanks for another great video.
I put a heavy duty cardboad box, with the flaps folded in like you're storing something in it, under where the diff. would fall out on the floor. That way if I don't catch it, the box DOES.
Great victory Wes, you're what's known as a community mechanic, you look out for your customers and help wherever you can, best mechanics you can have.
‘It would appear that we got the right part’ - Another bang on line. Sounds like you, as I, have pulled may things apart to fix an internal problem only to find the replacement was close but no go. That is usually followed by some choice words ! Keep up the great videos 👍
I'm doing my 93 e 150 van speed sensor. It's looking more like the tone ring . Weird stuff progressively happened. The cruise control , then speedometer, went to default shifting by tps? Replaced almost everything, ring is on e of few things left still working on electronic part.
Glad I found your channel. Subbed. My 94 f-350 idi has intermittent blinking OD light with hard shifts, AND the speedo jumps, but only at or above 60 mph. Any ideas? I’ve replaced speed sensor and tach sensor, haven’t found any bad wiring...yet, at least.
I know this is old, I’m sick and just watching everything lol. My 95 f-150 ALWAYS had a 1/2 mile bounce. Always was worst at about 70+. After I first got it it started bouncing hard and flipped the OD light flash. Replaced PSOM and fixed that. The bounce didn’t go away until I rebuilt the rear end after the pinion bearings grenaded. It was literally tiny pieces of metal on the tone ring made it bounce. Now it doesn’t anymore! These things are super sensitive. You also don’t have to pull the ring off the carrier to change the ring
Loved your debugging approach to fix this problem. My inner nerd was nodding and smiling when you got out the Function Generator! Perhaps a glitchy connection for the shifting issue still? Shame about the F-150 but I can see the owners point of view. If this was from any kind of dealer with a location, I'd spend a few weekends out front with a sign saying they are thieves myself. If nothing else, save the next guy some heartache.
Same thing happened to my 2002 E350 7.3 but I don't have a speedo cable.I replaced the VSS on the transmission and the sensor on the rear differential but still neither speedo or odo work. Any ideas what the issue may be?
the guarentee i would have gave him on the f150 is "i gaurentee you will have more troubles" i use the standard brand phasers as they have been fomoco parts with the part numbers ground off. they are less expensive than ford and i have never had any trouble with them. i should have offered up a complete used replacement set up i removed from an engine that had been in a wreck and broke the block. it was all quality replacemnet parts. i kept them in case i came across such a situation.
LOL. Are they really that bad? I think European Fords are OK. Not anywhere naar as good as Toyota but i don't see them broken down along the side of the road either.
Did this solve it? I picked up a 94 f150 for cheap and replaced the Rabs. Seems better but still shifts off. Fluid good. Have a replacement psom but haven't installed yet. Only code that came up was 452. Thinking maybe mlps beyond that. Replaced ujoints because when I shift into gear there's a small delay and then it shifts and kinda lurches. Seemed like u joints but that wasn't it.
Hey Wes... you nailed that diagnostic. Well done. BTW: You should think about getting the spreader tool. It makes the job SOO much easier and they don't cost very much. I got my used Chrysler tool on eBay for about $30, with the postage. My old Dana 2-bar, one screw, tool was less than $10 at a flea market. The old ones work as well as the newer "box" style and they're not hard to find. Most folks don't know what they are. And, then there are the rears that are so darn tight that they won't budge without a spreader.
I hope those weren't the Harbor Freight recalled jack stands there son!!!! Kinda cringed when you lowered that POS truck onto them. Also, didn't mama bear say she never wanted to see that truck again??? Guess she was out of town for this fix...
I have rebuilt several diffs for friends, never had the spreader tool. My worst was a diff I rebuilt on a Dodge WM300 Power Wagon. Rebuilt it put it back in place, lubed and tightened everything. On the test ride I had one speed forward and 4 in reverse. Damn thing has an even bolt pattern all around. It was not MY fault I put it upside down into the pumpkin.
DAMN Wes. That half meat van is giving you grey hairs. Time to toss in the road flair and declare it a complete loss. Maybe that is only protocol in "north Idaho" a.k.a. mini California >:- (
Man the owner is going to have more money in that truck than a new one. Good job on that. Transmission sounds like a shifting valve sticking. Bummer. Thanks for sharing.
Ah man! Wes I was waiting for you to pull out a time-domain reflectometer and measure for wiring harness issues everywhere else, but at least it was the tone ring and probably the tone ring 𝘵𝘩𝘪𝘴 𝘸𝘩𝘰𝘭𝘦 𝘵𝘪𝘮𝘦. I love it when a plan comes together. Edit: Whoa! I had no idea Ford made a 5.4 diesel! That thing was noiseeeyyyyy!
When it comes to the 5.4L and you're having timing and cam issues, it is literally cheaper to just replace the engine... Especially since there are no cam bearings. If you don't have timing issues, those engines are bulletproof.
When i use aligater clips with wires on my alternator the car starts and runs .i tried buying new connectiors and splicing the wires but it keep dieing ans wont stay running. Its only a 2 wire plug that plugs into the alternator. My car is 2003 mustang v6 base model.bit sure why new plugs that i splice in wont work. Any ideas ? We spent 47 on a brand new female connector and it isnt working. And the alternator is relatively new.
Awesome video! I am having an abs issue but speedometer is fine. After 3 rear speed sensors My mechanic said it’s the tone ring giving erratic signal. Would the tone ring make bad signal But still give good speedometer??
I got a 94 F150 the same issue. Tried many things. Just replaced the throttle body sensor, seemed like it was gone. Can’t right back today. Down to mlps or the tone ring at this point.
I wonder on the tone ring if you checked with a dial indicator? Look at the distortion in your waveform would correlate to the oxidation/normal sections of the tone ring?! Either rust jacking or heat distortion due to the rust?
I think I can believe that pitted generator gear is responsible for the problem. Remember the tone ring sensor amplitude is a function of the average tooth height, or alternately distance from the tooth average top to the sensor. I bet if you put a mic on some of those rusty teeth they will be off by a few thousandths, especially in the center of the tooth where the divots are. When the spacing to the sensor isn't many thousandths, that is a big deal.
Isn't it a wonderful thing, a speedometer that you have to have a tone ring inside a differential and a computer to measure the speed. For years we had a nylon gear in the transmission and a cable with another nylon gear and a mechanical unit to read it. It took 4 1/2 hours to fix the damn thing, this is a completely unnecessary amount of BS that some nerd decided was better. I have put 300,000 miles on units that never had a speedometer problem and others might get noisy and need the cable pulled out and lubricated or replaced which might take upwards of 15 minutes. Technology is wonderful you take a simple thing and make it a nightmare, the computer age is wonderful.
Pretty sure ring gear bolts can always be reused. Atleast in DANA axles. Also I always use a rag in the ring and pinion to pop the diff out. Less chance you will nick something.
Wes, do you ever get to work on something that less than 200,000 miles on it? Seem like you are the man to take a High mileage vehicle too!! Nice videos!! I really enjoy your troubleshooting level!!
It would be a lot easier, faster, and cheaper just to replace a speedometer cable than to fight all that electronic junk. I don't know why auto manufacturers think everything has to be electronic. To me it's just a source of trouble and expense.
