Good day folks!

I needed to replace the center support bearing in the 2800 e3, so might as well upgrade!

Thought I’d share the install/review of a very nice product: JXB Performance BMW10A0 (link below).

Install took all of about an hour, tools out to tools in. No dropping the driveline. No fighting with that 24mm nut. No removing the guibo. You cut the bearing from the rubber support of the oem CSB, smooth out the rubber, clamp on the new JXB support, cut off old CSB, and test drive. Dropping the exhaust may not be completely necessary, but it does give you all the room needed and limits the curse words. I dropped it midway through.

Link:

Test drove for about an hour around town. No vibration what so ever. Very smooth. I opted for the street compound as I’m not bang shifting (all the time ). Super happy with JXB Performance. Customer service was instant. The president, Jay, even answered my questions on a Saturday. Haven’t come across that level of service in a long while. All that being said, Jay has a customer for life here. The 2002 and the e9 shall get the same treatment in the near future.

Cheers,
Rich

Does it also allow for fore-aft movement?
From the images it seems that it's just static in that direction.

I do see the benefit of the mounting, and it's cleverly engineereed. I always like those solutions.

I just have more time than money....

Yes, there is a minimal amount of fore/aft adjustment. The rubber isolation pads are tapered to fit down to the depth of the bearing, so I just centered it the best I could, which turned out well. Also has a bit of port/starboard adjustment as well. Helped to clock the bearing housing square to keep the driveline inline.

I understand the time vs money dynamic, believe me! I gave up two months of coffee and microbrew! But it sure ended up being a good investment for me since I have been told by the doctor to control my stress level :)
 
Hi guys; can anyone think of a reason why BMW designed the OEM CSB, other than low cost and NVH, the way they did and not a more rigid support such as this one? Does a driveshaft need more a bit of 'give' or degrees of freedom for some reason?
