My 5-speed SC is making a clunking and banging in the rear when you accelerate suddenly or after shifting a gear if you get back on the gas about half way.
Under very granny style driving its fine but hit the gas and then BANG. It sounds like its right under the rear seat or in the trunk. I am not sure what it could be. My first guess is the rear diff is hitting the bottom of the car when the pinion angle shifts. I have about 2 year old poly-diff bushings and u-joints, so I wouldn't think they would wear out that quick but maybe the bolts came loose?
Another thought is that I tore the rubber tranny mount and that is causing it to smack under the car when the motor shifts. My friends Z28 was doing this before I changed the trans mount on it.
I had new tranny and motor mounts put in about 2 years ago but they were crappy liquid filled. If I have to do it again I'll buy the solid rubber ones. Now that I'm not working I don't have extra money to spend on the car for anything other than gas and oil changes. So hopefully this is something I can fix myself and cost me nothing.
Anyone have any hints at what I should look at? I'll be under the car this weekend to change the oil so after that I'll back it onto the ramps and slide under the back of it to see if anything is loose.
