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

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

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

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

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.

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.

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!

Super video, make more of those!

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.

awesome, better than Bob Ross 🙂

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

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

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

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

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

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.

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.

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.

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