Hello again!
I have been driving my 350ci Cutlass wagon converted to a 5speed for a week now. Everything seems to be ok with the exception of a driveline vibration under heavy acceleration. I never had this issue before I swapped out the 2004R trans for a T5. So I am pretty sure its not in the rearend. I did notice that when I put the newly shortened and balance driveshaft back into the car, had to shorten it by 3 inches, I could wiggle the driveshaft up and down on the axis of u-joint cups that bolt to the rearend. It would move about 0.025in or so. The centre of the u-joint would move between the cups. This u-joint uses the c-clips inboard the bearing cups to centre it. It's like the cups or one cup is not getting pushed onto the u-joint all the way. But the c-clips are in there respective slots. Has anybody seen this before? I installed heavy duty u-joints when I did the 2004r install adout 10k miles ago. The car originally had a th350 in it. The inside of the u-joints looked great, and they have lots of grease! I am wondering if this vibration is from this little bit of play? By the way it is fine when I am just crusing around, its only noticable under acceleration. It also get worse the faster I accelerate. Any comments?
Cheers,
Zeder
