What is causing the noise when I hit a bump?
I hear a terrible noise when going over bumps. My 62 bel air sounds like the undercarriage is falling off when I go
over a bump. Nothing under the car is loose. Engine and tranny overhauled. What is making this noise? Could it
have to do with the suspension? That is the only thing i havent restored on the car Any help is welcome.
Since you haven't done work on the suspension, I'll say the rubber bushings are probably dry and rotted contributing to the noise. Your shocks are probably shot as well.
check upper & lower control arm bushings. also check the exhaust for clearence & rattles .
