BMW noisy differential repair | bearings and seals replacement | E82 E90 116, 118, 120i, 316, 318 

Seriously professional work. There are very few people who can repair things to this quality level.

Amazing!!You are a rare find. People don’t do this anymore..

Great video. I do these a bit differently. I press the bearing cones in and then fit the pinion and bearings in plus the prop flange BEFORE fitting the seal. I tighten the pinion nut up to compress the spacer until there is 95% zero free play but the pinion still spins freely. Without the seal fitted you can feel a minute amount of play. Then mark the nut to the pinion, remove the flange, fit the seal and refit the flange, tightening the nut to where it was before but fractionally more. You can do these without a press (I don't have one) using long thin chisels to remove the cones. Be careful not to mark the diff casing or the shim. The big one is very tight. I get the casing nice and hot before fitting the big cone that I leave in ice cold water. I find the worst bearings for wear are the Japanese KOYO brand, very bad. The side circlips are also shims and must be marked side to side. These days I never replace the diff side bearings to keep costs down - they are rarely worn like the pinion bearings. I use EP90/140 synthetic oil as well - the original oil is too thin, the reason these diffs wear out. I've also found that many diffs only need the small end pinion bearing replacing, and that the big one is still serviceable, even on very noisy diffs.

That´s that i call professional services !!! Good job.

When I first watched this thought he used the angle grinder to basically cut the bearing seat off, nope cut a slot to place a chisel so would have a solid ground to smatch it off ,very very much so impressed.

Danke für das tolle Video. Dadurch konnte ich mein Differential selber reparieren!! 🎉

This is above my pay grade but you may have helped me diagnose my issue. 2011 e91, 6 speed, decelerating from 40mph and noticeable whine from front end. Thought maybe front drive shaft. Not. Maybe differential. Great vid!

Can't wait for my lsd conversion kit to arrive and help with the open diff 'issue'.

You should mark which output flange was which when disassembling. Same with half shafts. The splines have been stressed in one direction during use and can fracture if replaced on opposite side of the diff as the stresses are reversed.

awesome, better than Bob Ross 🙂

Super video, make more of those!

Great video, very informative, is it required to set the backlash or it purely dependents on tightening up the pinion bearings correctly? Thanks.

Very educational video. If you have the opportunity to measure the height of the new 215 type shank spacer, please let me know. Thank you. My front shank bearing is noisy but I don't know the height of the new bushing.

In this video it only shows how to remove 1 pinion race. How to remove the other (the larger race?)

Great Video in one step you mention to not mix up the C clips somebody knocked the parts tray. How can i measure wich belonged to wich side? Thanks and many thanks for your effort on the video. Greets

Another nice video, thanks for giving the dimensions of those pressing tools. What kind of paint /brand of paint was used? Also the sealing compound? Looking forward to video on how to set the backlash on a ring and pinion replacement.

Fluidified... my kind of music :) always nice to hear

Do you reuse the old pinion shim or did you install a new one? Thanks

Very nice video.. and satisfying, thanks for sharing! Does it work for the e91 (320d and 330d) as well?

Super gemachtes Video. Es wäre noch besser wenn ihr die Drehmomente angegeben hättet anstatt den Deckel mit dem Schlagschrauber zu verschliessen

thanks for this great video. I don't know where to buy the key you use to check the pinion. Can you give me a name of any company that sells it? Thanks in advance.

Hi, I have a question, there's a difference that the ends of the circlips goes up or down? The differential it's a 215L from a e90 330d 2006, there's no an oil passage on top, I'll appreciate the answer, thanks in advance.

Wow, amazing video. I love people who repair things instead of throwing and buying new one. Just curious, how much do you charge to do that ?

I have TIS , Bentley and Haynes literature for my BMW but in none of this i can fint the values you pubblished on youtube. My car is a E90 2006 330xd european and according the ETK has a rear diff type 215L. I found accross bimmerforums values ranging from 1.5 to 2.5 Nm for new rebuids and 1.0 to 1.5Nm for my differential after run-in. These values are almost double yours. Are your values from your personal experience or are they comming from BMW?

Thank you for the video!!!! What tool do You use to measure the bearing torque?

How did you get out the bigger pinion bearing cone? I failed right know to get it out.. I am thinking of leaving the old one there because a damage is not recognizeable. Thank you for your great video and inspiration!

Great video!! What torque meter are you using to measure the preload? Also I didn’t realise the circlips were different sizes, do you know the correct thickness for a left hand side snap ring on an e90 188size diff? Thanks for sharing this information and I will definitely buy from your company in the future.

Nice video! Do you happen to know what s the good value for setting carrier unit preload in bmw 168 diff?

BMW E91 330D differential 2.35 215 type LW

So the seals can be replaced by just forcing them out and pushing new ones in? You don't need to open up the entire diff just for this, do you?

Hi, thanks fo excellent video. output shaft, should there be play? or are they soild tight?

Hello. I have a problem with the front differential, BMW E84 2103 (184 HP) and I have to replace the 2 bearings from the pinion. Can you tell me how tight the pinion nut should be tightened? I suspect that the procedure is the same, the measurement will be done under the same conditions as in the video above. Thank you very much!

Hello, I have one question - I almost replaced the differential on the bmw 118d 122hp 2007 M package in service and they put the bmw 120d differential instead (since it doesn't break down like they said) and I noticed that my car in the same RPM has now less speed then it had . For example, in the sixth gear, the speed was 195 km / h at 3,000 rpm, and now it develops 180 km / h at 3,500 rpm or less. Is it differential problem and which should be put to be as it was?? Thank you

Great Work guys!! So if my differential makes whining noises when releasing throttle it's the pinion bearing? Or is it possible that it#s also one of the side bearings? Or even the ring or pinion gear? Thank you and kind regards from germany! Currently waiting for your LSD Conversion Kit to arrive, can't wait!

My questions is why You don't change teflon washers located under the small gears "satellites" In my experience, it is these washers that are responsible for the play that forms in the drive axle, the bearings last 300 to 500 thousand, unless the car was drifted by a young driver. Regards

How much do you charge for a rebuild?

I have a badly reconditioned differential at the moment and I’m trying to re do it myself. I don’t know if when initially was reconditioned, they have fitted the c-clips the right way. Do you know what dimensions this c-clips should have? So I can find out which one goes left and which one goes right? Thank you.

Did you check the backlash when the re-build was complete? It's not shown on the video.

hello. i mix up C clip😏. one is 3.28 and other 3.68. from your expiriance where put the tallest one?🤔 thaks a lot.

Thanks for the video! I have replaced the bearings, but i have a noise. Is it possible that i switched the left&right clip? Looks like gears singing.... Greetings

hello, how much would a differential reconditioning operation like this cost me? Raport 2.58 e91

Thanks for this nice video! In my case, the nut is still very, very loose when the clearance is already 0. Would you know what could cause that, or is that normal and does it need loctite? Thanks!

Did You buy a repair kit for all the bearings and Sealings, or just clean the old ones..?

I'm in the process of redoing a differential on a 2013 114i, it's a 168mm but "LW". Between the two conical bearings of the pinion connected to the transmission shaft I find a deformable ring on the axle but there is also a ring on the housing with two holes (certainly to lubricate the axle). It gets in the way of removing the outer ring of the bearing on the transmission shaft side but I can't find it as a spare part. Do you have any information on this?

Do you have kit for 04 BMW 325xi 2.5l sedan awd 3.46 my bearing are making hollow sound

Pozz majstore. Imam i ja taj diff na e90 pa imam jedan mali "problem", 6 rucni mjenjac. U drugoj brzini (i samo u drugoj) u neko vreme cuje se da nesto pomalo zuji. Ma skoro ko da je zupcanik druge brzine ravan kao na turnom autu za utrke. Ne primeti se to toliko, ni drugi ne cuju, cuje se bas simpaticno da kazem, ali sumnjam da je krivac u difu. Ni kod jedne druge brzine se to ne cuje, ne suskaju lageri, ne kuca kardan, nista. Samo malo pozuji kad ga vozim u drugoj brzini. Isto tako ne baca mi iz nijedne brzine, sve radi normalno. Ako je to dif, naravno da se cujemo sledece godine, da ga sredite

One question. Does the oil from differential goes on the outside bearings (going to left and right wheel)? The ones that you popped out with hammer. Or outside bearings have their own grease? Also, pinion bearings as well?

Do you work on other cars? I have a 2013 BMW 128I, M sport with the whiny, noisy rear end l. It was swapped out for another one and it sounds exactly the same. Could it be something other than the rear end? I was reading that these are problematic. The car only has 60,000 miles on it. Can I send you a video? What is your location? Thanks, Ken.

Torque specs for The diff cover? Thanks

Using a grinder and no pullers to remove bearings is a hack job. I know has I have repaired more than 900 of these and I kept the used bearings to prove it.

Hello, Great video ! I am from Holland so sorry for my englisch. Soon i start rebuilding my diff of my e91 318i from 2007. Finally i found de specs for the pinnion bearing in your video!! But what About the backlash or is this the same before you take all apart? Greetings, Vincent

Was that assembly lube applied onto the bearing cone(before pressed in) and the bearings as well ?

In the process of doing bearings on my open diff, 188l , great video has helped me have confidence to go ahead with it myself, although I think I'll have to get someone else with the know how to tighten the pinion shaft nut correctly. Differential has a constant whine only changes with road speed,put it on stands spun the wheels to 100kmh, noise is from differential box but no sign of excessive wear on bearings, I'm starting to think it's the gears making the noise not the bearings, any ideas?

Did you change the planet gears?

Hi how can I know which bearings I have on the differential (168, 188 or 215)? Thanks

How do you check crown to pinon lash ?

hi the link gives error 404. is the diff kit still available for E30 diff? what tool did you use for such low torque reading? is it a specialist tool for diffs?

Have you replaced Bearings on a E9x M3 diff? Same procedure or any thing different?

Is this diff same for 520d, my diff is making a clunking noise on light acceleration when taking off. In guessing the shims need replacing or increasing.

Great video! You wouldn't happen to know what the pinion torque spec for roller bearings in a 215K should be? 🫣

whether you can write bearing markings, or replacement bearing markings

Very cool👍🏻 Do you know which spec for 205l(ball bearings)?

Hello what dynometric force should be used to tighten the rear nut???

Which of these bearings is the one that most commonly fails on the 320i please?

How could you expect this to work properly when the gear mesh was not even looked at? Typically when changing the bearings you will have altered the relationship between the pinion and ring gear, requiring a change in shims to insure they mesh together properly. The process as I have seen it involves marking compound on the gears, rotating them together, and observing how the teeth contact. Adjustment may have to be made in the fore-aft position of the pinion, or the shimming of the ring gear.

I rebuilt a bmw front diff, everything seems to be fine (not fitted yet) but i'm wondering why there is a spring plate/preload washer under a side bearing? When i put the cases together, i think i felt a resistance when screwing in the bolts. Could it be the washer/bearing fitting in? All assembled it seems to spin quite nicely by hand, set the pinion nearly to the same mark with a new crush sleeve as it was, as a starter.

I am repairing a F20 differential which also make noises, do you know what the torque values are for the pinion bearing? The inners of these diffs are exactly the same as the diffs found on the E90-E93 and E85-E89

Did you used the same crushed sleeve or put new one in?

hi! after rebuilding my differential as the video said, i get a noise on deccelerating / engine braking, like something is vibrating / rubbing. any ideas on what i might have done wrong?

Do the customer have to buy differential oil or it is included as a part of your bearing and oil seal service?

Today i finish rebuild my 168l diff and i can see The backlash is about 0.15mm. this is todo much, i need change my Shims?

How much is the tourque for the pinion bearing?

Can you change the side load bearing where the axles slide in with out doing the whole diff, or removing the Diff pinion and ring? Just those bearings are bad from a lift on my e83

Is there any chance you have the torque specs for the BMW Mortorsport (E9x, etc.) pinion bearings?

Do you offer an exchange service for these diff's?

if the pinion nut is to tight after rebuild will it be whining if this is correct can it just be loosened and corrected or will the crush ring need replacing again ?

Does the pinion make noise at all just got a used diff and its clean but the pinion still makes same noise as my other

How much, where are you from and do you do exchange (you keep my old part and send me a refurbished one right away)?

Hi Nice job Can you provide me the measurements for the bearings?

Any idea what the preload is on the 168 pinion new bearings (rotational force)

Hallo Was kostet bmw hinter Differenzial Überholen Lg

I’m so mad to the BMW. Mine is f30 and the differential gear is broken. I have never heard that are broken before. So wired car.

All that could of been done in 1 hour max without any tools.
