Default My 1965 Corvette Making Sound
Can you Corvette veterans please help me?
My 1965 corvette L79 makes a bump sound from the rear when i remove my foot from the accelerator.

Any idea what it maybe? It just started.

I could tell you that you are not supposed to take your foot off the accelerator,
OR
I could tell you the C8 section is the wrong section.

Take you pick.

Terry, from your limited description my 1st guess would be a U-joint. Got a 1963 myself.

The C2 experts follow the C1 & C2 forum. The guys will start asking a bunch of questions to diagnose. Did you realize you’re in the C8?

Don't ask the C8 dudes difficult questions, their hobby is needlework. Not a universal, you would have a vibration all the time. Check trailing radius arms/links or spring clamps or differential or gearbox or left engine mount/mounts or, exhaust mounts. Does the car change direction when u do it? Lower control arm bushings, tie rod, steering links.

Like the other guys said, probably u-joint. But check anything back there with a bolt for tightness. You'd be surprised how many things can come loose over time. Nice car, btw.

You already posted one thread asking about this where various people took time to answer you - so what's the point of a second thread ?
