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

How to rebuild noisy differential from BMW 118d.
If you have whining noise while driving, especially when you release throttle, than you will definitely need to replace bearings in your differential. The video shows procedure of bearings and oil seals replacement with addition of refreshing housing and rear cover
When doing that, it is essential to tighten pinion nut properly. Otherwise pinion bearings won't last long. Not many people know exact values and those who know won't share them. But we do, so here is torque spec for all 3 BMW differential sizes:
- 168L (ball bearing) - 0.2Nm - 0.4Nm
- 188L (ball bearing) - 0.4Nm - 0.6Nm
- 215L (ball bearing) - 0.6Nm - 0.8Nm
We have complete reparation sets available, which include all parts necessary for rebuild:
1x small pinion bearing
1x large pinion bearing
2x side bearing
1x pinion oil seal
2x side oil seal
1x crush sleeve
Link for purchase

Such kits are available for all BMW differentials.

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!

[@leonsletterbox2013]

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.

[@MyNameIsJustinKeenan]

works great for wheel bearing races stuck on hub surfaces as well, (can be a bit more difficult with thicker bearing material) cut down almost through the race and then chisel to split it in half, race slides right off then.

[@beigemanalishi1645]

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.

[@MyNameIsJustinKeenan]

[@briancollison5319]

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.

Thanks for sharing this information and I will definitely buy from your company in the future.

There are many makers of torque wrenches. They are all ok. Just make sure you use the one which measures 0-5 Nm. Each diff has its own snap ring measures. There is no default size.

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?

Oil lubricates all bearings.

You have to measure backlash. No one knows thicknesses as they differ for each differential. Measure backlash, you should have around 0.06mm.

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?

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

[@RacingDiffs]

You put a shorter gear ratio differential. Check another video on our channel on how to determine which gear ratio your BMW has. It will help👍🏻

[@chrisleat5390]

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

[@RacingDiffs]

We always check it, but it's not necessary since bearings are made to 0.001mm tolerance. So, if there isn't wear on gears, you can simply return everything as it was.

[@ToyaAp]

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

[@RacingDiffs]

Could be. If backlash is not correct, nois can occur.

[@TheEVOProd]

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?

It's not recommended to return old bearings as they were in the same environment with broken bearings, so metal particles possibly damaged hardened layer of bearing cones.

@@RacingDiffs nema problema, samo sam pitao u slucaju, da trebas to recimo hitno. Svaka cast, zelim vam puno srece i posla. Kupio sam neki E91 s ovim difom, vec je bio mijenjan pa ako u nekom slucaju sad ovaj rikne meni, znam koga pitati. Pozdrav iz Slovenije.

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

[@RacingDiffs]

Of course. For ball bearing 0.2-0.4 Nm and for roller bearing 0.4-0.6 Nm. Measured without carrier unit inside of course.

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.

[@RacingDiffs]

Bearings are made in 0.001mm tolerance. So if you return adjustment shims to their original place, there won't be any difference.

Thats a great information from a Professional! Ist this your daily work? How much Diffs did you fix? Best regards, Stephen

There are a couple of mechanics in the company. We have 3 diffs daily in average. I'm glad you liked the video👍🏻👍🏻

Wow, thats a lot ! Thank you very much for this Video, now i am looking forward to fix my Diff ! Best regards from Germany, Stephen

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.

Sadly, quality grade drops with years.

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

[@RacingDiffs]

Thank you! It should be 0.6-0.8Nm without carrier unit inside👍🏻

[@Robert.K]

​@@RacingDiffs Thanks for replying. So the same specs apply for both ball bearing and roller bearing?

[@RacingDiffs]

Pretty much 👍🏻

@@RacingDiffs Thanks 👌🏼
