Ford F-250 Rear Differential Service and a new cover. 

Thanks Bro... I appreciate it!. Ya, it's been pretty busy around the compound these past few weeks fence building, and landscaping improvements while trying to squeeze in mechanical repairs when possible. The weather has been just foul. It's snowing a ton in the mountains and so the snowmobile season is ON. That initial cover it turns out, was for my truck but fits the front end housing which is why Amazon's fit recommendation in the end was correct. I made the assumption it was a rear cover but no, it's sort of an armored front diff cover that is popular with the recreational 4X4 off road crowd. My truck has a Dana 50 front axle and a Sterling 10.5 rear (tag says 3L73 10.5, The L indicates limited slip and 3.73 is the ring to pinion gear ratio, 10.5" ring gear) with limited slip gearing or what is sometimes called "posi-traction". Limited slip directs the power to the rear wheel with the most traction vs an "Open Diff " which directs the power to the tire with the least traction- That isn't helpful in snow obviously. L.S. is not to be confused with a locker which locks both rear axles solidly together and can be switched on and off. I'm going to service the front as soon as the lube gets here. Same stuff by Redline but a different viscosity. I sort of wish I hadn't sold the other cover now... Dang it!

I replaced all my sway bar bushings in 2020 when I did the steering. There is a 3 part series on the steering replacement on my channel. I did the pump and hoses. The steering box is by Red Head steering gear. Tie rods. Track bar and all the bushings and sway bar links both front and rear. All new parts from Moog Suspension. Then had it aligned. Not sure what you saw in the video that made you think the bushings are “toast”. But the bushings are all new. I tow a 10,000 lb Vengeance Rogue Toy Hauler using a Blue Ox load distributing hitch. I also have Air Lift air bags with the onboard compressor and Bilstein gas shocks on all four corners. I also changed to SSBC 8 piston calipers and vented cryogenic treated rotors. This truck runs and drives better than new. Thanks for watching.

Ya, I had to go back and look at the bushing shot in the video. It's just dirty. I had been up in the mountains towing my snowmobile just before Xmas. The bushings come with a split in them which per the manual faces down toward the ground. The front ones came in a purple color and the rear ones were black. They are new. However the old ones as I recall looked pretty good. This truck only had 37,000 miles on it when I bought it in 2012. It came out of Oceanside, CA. so it was pristine rust wise. It was owned by a lady there who had horses but she didn't use it much. So I nailed it. Just lucky. The bed wasn't even scratched. At 120,000 miles I decided to replace all the steering components. I made 3 videos getting that done. It was quite a job. I didn't get the power steering pump and hose replacement filmed. But the rest of it is documented. Like I say, I also replaced the sway bar links at that time. I love doing this sort of stuff and I drive my truck towing the toy hauler from Tacoma to Orlando every winter and back with my Indian motorcycle in it. So, I set this truck up for towing heavy.

Hi KCC, I change my oil every 5,000. I run an Amsoil bypass oil filter setup which gets me 5000 easily. I run 16 oz of Archoil AR9100 Friction modifier in Shell Rotilla T 15/40 and a Baldwin main filter. At 5000 miles the oil still looks very clean. I change oil right before I leave. It's about 3,800 to Orlando. I change it right before I head for home and that's maybe a little early. That gets me home and I have about 1000-1500 left before a mid summer change. Sturgis is in August. It's about 2,800 round trip. Trans gets Valvoline Max-Life per my video every 15,000. I run Red Line Full Synthetic in both diffs. Front is 75W90, and the rear is 75W140. The Red Line requires no limited slip additive. My transfer case gets changed every 15,000 and it gets Motorcraft Dexron LV which I believe is a full syn. I just started using the Dexron LV due to a Ford Service Bulletin. Prior I was using Valvoline Max-Life multi vehicle- same as the trans. Mainly... never use Dexron V in the transfer case... per Ford's most recent info. I have videos covering most all of this service work. I hope this helps. Craig
