Resolved Noise Only In 1st & 2nd Gear

[JackStieben]

I have a '97 GST and very recently a loud thwaking noise ( I believe is coming from the drivers side) only when I'm accelerating somewhat fast in 1st and 2nd gear. If I let off the clutch slowly in those gears, it doesn't make a noise. 3,4,5,R are all fine. When I heard the noise, I replaced the CV boots and steering rack boots as they were ripped, and the wheel hub and bearing. The bearing was shot on the drivers side. After that I changed the tranny fluid with pennzoil synchromesh (no metal was in the old fluid). I assumed that would fix the problem but it didn't. I then noticed that my plastic covers for the timing belt were a bit loose and rubbing on the PS belt and a little on the timing. I tightened them down so no more rubbing from up top, but to no avail. Still the grinding thwaking noise. It sounds similar to something rotating maybe and hitting something else. I decided that the TB covers were only hitting from those gears because the torque of the engine was moving it forwards then back to normal. When I get off work I'm going to check down by the harmonic damper and check all the motor and tranny mounts to see if they're bad. Is there anything else that could be causing this issue? No one else seems to have the exact problems I'm having. Thanks in advance

sounds like those gears might be worn out

Actually. Turned out that the drivers side motor mount was bad. The rubber insert had ripped in half. New mount and it was good as new

Nice! And just look at all those other things you got fixed by taking the long way around things to fix the problem.

Yeah even though it seemed like a pain in the ass then, I'm super glad I got all the other stuff done. The new boots are good since anything could've flown into my steering rack and surely screw me over. Plus one of the wheel bearings was shot anyways. So all in all it was a good lesson for me.
