Need Help Now!!!!
Alright just got done installing a TCI 3500 stall, trans go shift kit, and pacesetter headers on my buddies 98 Z28. Started up fine, then went to move it and about 10 sec. into driving i start to hear this bad clank sound. Almost like somthing is hitting somthing under the car.
Does it only when the car is rolling, doesn't matter if the car is on or off, and the noise speeds up the faster we go.
I got under the car and makes it when i spin the driveshaft with my hands, sounds like the sound is almost coming from inside teh driveshaft.
I then tried pulling the u-joint bolts out and re torqing them down just to check to see if that did it. Made the sound a little when i was doing the final tq. on them.
Lowred the car back down, started her up, started to go for another test drive and made it about 20 sec. this time and there the sound started again.
I'm at a total lost right now and really hoping one of you guys can help me out
Thanks

Did you put that cross member back on that holds the y-pipe up? that helps tighten things up. The y-pipe is probably really loose.
My y-pipe bangs my floor board every now and then. But I wedged a rag on top of one of the u shaped exhaust clamps so it won't come out. Doesn't bang anymore.

Get the car on jack stands. Slider under there with a creeper. Put it in neutral and turn it. Use a flashlight and see what it is hitting.
My y-pipe banged pretty bad but with the revs of the engine. Got under there and tightend some stuff up with a rubber mallet and it didn't back so bad. Definitely sounded bad though.

hmm
i dont think its that, ive got a good 5 inches of clearance between the two. when im turning hte driveshaft by hand, every 5mm or so of rotation, it clicks. Its not a normal clicking either, it almost sounds like a really big ratchet or something of the sort. Thanks again for the reply

Also did the TC seat three times? I'm sure it did if the tranny lined up. Did you put tranny fluid in the TC before installing it?
Did you guys take the driveshaft completely out of the car? I hope none of those needle bearings fell out of the universal joint. That might be something to check.
