Be aware how deep the original seal was. Better to measure before replacing it. If you push the seal too deep than it could close an oil passage. The consequences will come a little bit later on.

Not often you see a tutorial so clear and concise. Gives me the confidence to try to tackle this 10 minute job that will take me 3 weeks.

That was the best. You don’t see this in the dealership anymore. These new technicians don’t know what their doing now a days. Great video. That’s how my auto shop teacher would have done it. With out some stupid over priced tool.

Worked great just did it on my BMW 850 Differential today

I like how you keep referring to your prybar as "that mofo". Think I'll label mine as that from now on :D Thanks for the helpful video!

I think he was referring to the shaft

thanks for the info, I was just about to change them.

Great vid ! Thanks

Awesome video, thanks alot!!

I will be careful when I replace those MOFOS.. The video was excellent. Tks

Hey man, Nice job. You make it look easy but since I was paying a guy to help me work on the rear suspension of my Z3, I let him do that for me. Today, I rebuilt my inner cv joints and noticed that the right outputshaft came out as I tightening the cv joint to it. Can I hammer it in myself to make sure it locks in place?

Good to know 💯

Thank you!

thanks!!

Be sure to protect the differential with a towel or a piece of wood to avoid damage or this could also lead to leaking

One of them won’t come out at all, any ideas? Tia

Does this work for an e28 as well?

Just about to do this with my diff out. I have to change diff mount bushings too. Do you have to drain the diff to change the output shaft seals? I plan on leaving it full when i take the diff off the car as i changed the fluid not too long ago.

Good question, I did not drain the fluid, replaced the seals with fluid still in the diff. Thanks for watching!

On a different topic, I’ve got excessive play on my output shaft that you hammered out causing clunking. Is my diff shot?

What kind of car is it, e46 M3? It’s normal for them to have excessive play on the passenger side. Thanks for watching!

My front diff is leaking. I’m pretty sure it’s the output shaft seal. Should I also replace the input shaft seal while everything is apart?

@Oofsmageroo

you could... but also make sure the small vent port on the back of the diff is open.. if that clogs its gonna push oil out of whatever seal new or old.

I have just done this on my 2004 e87 2.47 ratio diff and now I have reinstalled it in the car drove for a few day and now making a very loud pinging noise every time I touch the throttle or come off the clutch had a look underneath while someone applied load on the clutch and the ping noise looks like it’s coming from where the prop shaft attaches to the diff any ideas?

My seals come with small c shaped clips, where do they go?

@ProjectBMW

3 жыл бұрын

The c shaped clips “clip on” either the axle/ or output shafts (what I hammered off the diff). Depends on what model your car is. Your axles (and output shafts) should already have the c clips installed, I usually just toss the clips that come in the kit and re use the factory clips.

@@austinmerrival927 ya I just cleaned it up really well and seen it wasn't that bad, just mostly from the knuckle joint was sloshing oil over time. But I reapplied grease and rebuilt the driveshaft, new guibo, new, centering drive rubber thing, new cv joint gasket. I will take it back apart in the future because I severely want an lsd, so I will either convert or put an m5 diff in and lengthen the driveshaft

Truly is always one person to say it was done wrong..... SMH

Where was the grease lol

Thanks for this video. Great tips. Need advice on excessive clunking on my M3 F80 6MT when suddenly depressing clutch pedal to shift gears particularly at low speed/low rpm. Not yet sure if noise is coming from differential , or from flex disc & carbon prop shaft, or from transmission gearbox. Rubber mounts and bushings are all good. Any advice is highly appreciated.

I had this problem and when I replaced my rear main seal I went ahead and replaced the flywheel and clutch and my clunk went away.

Why doesn't anyone ever show how to do the diff bearings? Do they never go bad? Are they just so good or lubed that they don't wear out like wheel bearings? I would think they would be very similar. HELP ME! LOL.

2 mins, it took you 30 to remove the seal.
