1996 camaro vibration..need some help

[96camaro]

now this happens only at certain times..seems like around 35-40mph...there is a thumping type noise i can feel and hear..when i stop and take off again it may or may not start again..now if it was the driveshaft wouldnt it do it all the time?

Did you lower your car or replace the trans mount with an aftermarket one? If so the driveline angle may be off. Try to get a Sirometer from a local small engine repair shop and if you can tell me the rpm, speed and frequency, I could plug it into a tool I have at work to tell you what the vibration is.

no its not lowered or anything..i have dropped it off at a driveline shop for them to check it out..

well the center support bearing is trashed in that car..dam 2peice ds..so im hearing different things about putting in a 1 peice ds..any mods needed to do it..i have a v6..i was told to get one out of a v8

My s-10 had a 2 piece ds and I put that thing on bags, I had to replace the mid bearing might have been $30 and $10 for a place do press the old one out and press the new one in. Might be an idea, but Im not sure if they are the exact same design

Try to get an aluminum LS1 drive shaft.

If not a third or 4th gen steel one piece would work too.
You may or may not need to grind the bracket for the mid-shaft bearing off, depending on aluminum or steel.

i talked to a driveline shop today and i cam across a steel one really cheap..he said he does that conversion alot. so up to the shop it goes tommorow..i got a 1 peice out of a 98..
