Took the trans out, replaced 5th gear synchro, and put a NEW throwout bearing in because the old one was a little noisy... the new one is MUCH worse~ It gets better when it heats up, but is way too noisy when cold. I put grease on the contact points with the fork, and a little on the front (towards the front of the car) of the bearing, but couldn't tell where exactly the manual wanted it... these are sealed bearings right? How can I make it quiet???

I did not replace the pilot bearing because I did not have a puller for it. Mistake? Cause?

Also, though I marked and installed the driveshaft in the same orientation, I now have a bit of "gear" noise in reverse... ahh, help, I hate "fixing" my car only to have three new things wrong!
