I put a rebuilt driveshaft on my E30 about six months ago. I pre- loaded the center bearing (which came pre-installed on the new rebuilt driveshaft) and torqued everything as listed in the Bentley manual.
Have probably put less than 1,000 miles on the car since then with no extreme driving conditions. Now the center bearing is squealing loudly, usually around 30mph, but the noise is intermittent. Most noticable when the car is cold, but usually stops after things are warmed up.
A mechanic put the car on a lift, put in gear, and the center bearing was confirmed to be the source of the noise, which he described as sounding like a whale call.
The shop that sold me the driveshaft has a one year warranty on it and will replace it free, but of course that means a few hours of labor for me to take the old one out, etc.
Before I go through this routine again, I was curious if there was anything left out of the Bentley manual or some mistake that is easy to make which would quickly destroy your center bearing?
Thanks, Christopher
