Default Re: Throwout bearing

You shouldn't be having all of these problems. With all the work and parts swapping, I am starting to wonder if there aren't some alignment issues somewhere in there.

About fifty years ago, I had a '50 Buick special with a stick shift. It was a real clean car, but cheap because the transmission made a terrible noise. I pulled it apart (a bigger job than I had first imagined because of the torque-tube driveline) and replaced some bearings. It was OK for about a year until it started making the same transmission noises. I kept driving it until the transmission failed completely. Later, I was able to source a rebuilt transmission from Sears. I figured that my jury-rigged repair had probably not been good enough, but a "professional rebuild" would solve my problems. It did; for about a year, when I started getting the same noises again. This time, I took it to see an older friend who was the senior mechanic at the local Chevy dealership. After listening to it and my tale of woe, he said that I probably had an alignment problem with the transmission and bellhousing etc. and that it would take time and money to find and fix it. I sold the car the next week, as I couldn't take dealing with the torque-tube a third time.

The next time you have it apart, get under there with a dial indicator and a steel rule.
