1998 BMW Z3 Differential Bushing Replacement

- Here I captured the struggle of replacing the rear differential bushing on my 98 BMW Z3 2.8L. There was excessive movement in the rear and a clunk during garage shifts, the bushing was done.
Take-aways:
- Remove spare tire for better diff access
- Remove vehicle speed sensor prior to cover removal, to keep from damaging it
- Remove bushing bolt and support rear of diff with jack so you can lower and gain access to top cover bolts
- Be sure to press the new bushing in perpendicular to the hole axis
- If using, secure your hand pump hose so it doesn't fall in to the diff
PSA - the JB weld fix did not work, if you watch you will know what I'm talking about. It failed on the first stop sign pull-away. Awaiting parts now. - Авто та транспорт
I respect the hell out of you for not shouting every swear word known to man after that one
To be fair, you went pretty all out on the hydraulic press. Good learning experience here for you. The kind of mistake you only make once.
great video, helpful showing it all. i'll just live with the clunk at that point.
Is there a pattern for tightening the cover bolts? I did my e36 m3 cover and there was a specific order for tightening and torque
Checked my manual and TIS, didn't see anything specific to sequence..
@driventofailure yah cuz when I did my e36 m3 cover few years ago I found a torque spec and sequence page. Now I can't find. Just wanted to know if there was something similar for these.
Man to be honest if you have come so far till you've replaced the bushing, you should replace the LSD and the housing as well.
I don't disagree, this car is a rabbit hole of work because of its age. I did this because it was relatively quick and easy and I had a race that weekend. I plan to tackle the diff again when I drop the rear subframe for bushings.
@@driventofailure this is exactly my plan. I actually have the subframe, axles, differential, lcas, from a 3.0 I want to swap in but I daily drive the car so I've been pushing it off I need to just do the differential bushing. Gonna tackle it this weekend.
@@Bmw_Z3R pretty doable on a weekend as long as your careful pressing the new bushing in to the housing. I also made a video for the sub Bushings, rtabs, and diff rebuild later in the Playlist. Finally tackled that rear full on!
@@driventofailure hell yeah dude. Actually I'm just waiting for the dealership to get the diff cover gasket in $13 bucks is a steal OEM BMW too. My problem with the swap is apparently the 3.0 has a 5" wider wheelbase on each side to the 1.9 so I'm still debating the solution for wheel poke.
Nice video I need to do this as well. My 2cents worth for future DIY’s Some grease helps with install on all pressed bushings, even though they say don’t use lube it helps ! A local welder can fix that cover easily with mig welder.
That sucks.
