So after debating whether or not to do these jobs in my driveway I ended up going to my friends garage because it started to get a little colder outside. Went over got there Saturday morning at 7:30am ended up getting home at 7:30 PM. Exhaust came off surprisingly quick but it was superheavy all of you guys were right who have done this before. Surprisingly my center bearing was not totally torn through and actually looked not bad visually I have no idea why it was knocking so bad but it was really getting worse every day maybe the shaft was very much out of balance for some reason?
Diff pinion Seal was pretty straightforward and you don’t need any BMW special tools to do the job, I used a large bearing cup to press it in and it pulled out with a small pick. All the instructions on here were very helpful I was well prepared for this job.
So as of right now new Guibo, new driveshaft, new center bearing, new CV joint, new u joint, new diff pinion seal, all new exhaust hardware at the flange, fresh lifetime FCP diff fluid and this car drives AMAZING!! All small vibrations gone, seems like hesitation may have been related as that is pretty much gone, drives and engages do smooth now.. about $800-900 all in after my driveshaft core return, and I still have the spare diff bushing because the old one looked good so I did not touch that.
Tranny mounts look good. Shifter bushings look ok, some slight slop but nothing worth getting into even with all that out. Shifts great. BMW quoted me $2400 for that work and they were only going to replace the center bearing not the entire driveshaft...
Only took a few pics was so busy laying under car all day:
Maybe the u joint was stiff and bad since there is grease flung here? Felt loose and ok when I took it out..
Last thing. After we went for a good long test drive, came back to my friends house to hang out for a bit then I want to start the car to go home and the check engine light came on!
I remembered from reading other posts about the O2 sensor swap so we checked the codes and it was the passenger side sensors swapped, quick fix and I was on the road and no problems. I was glad I took this picture before hand, one of the few that I took...
