Noise in rear of 1979 Corvette
The 1979 corvette that I just bought makes a banging sound with a noticable viberation when I go from reverse to forward. I have been told that it could be the u-joints in the axle. First does any one have any other ideas what it could be and how hard is it to replace the u-joints. Thanks Gary B.

When I bought my 79 it made a similar noise. Mine would bang going into reverse. I don't remember if it did it going into gear or not. It was the rear end mounting bushing. You can get them in poly or rubber. Inexpensive and fairly easy to change. Might solve your problem and is typical to be bad on these older cars.
