I have a 1992 silverado 4x4 and when I go in reverse not all the time I get a loud bang and I get the same banging noise when I go over sudden bumps or dips in the road I changed the back u joints and same thing happens would it have anything to do with the transfer case thanks

No it just bangs once in reverse but if I hit multible bumps it will bang or sudden drops in the road any bump really it seems to come from the passenger side and I dont hear any metallic sound or grinding cant figure it out had my front end checked nothing wrong there could a cv joint do this or would it bang all the time Thanks Aaron

Its been going on for a while doesnt seem to stop me from driving its just a issue if I hit bumps and it doesnt do it in reverse all the time only when theres a bit of a load on it like going in reverse on a bit of a incline I think its in the front diff? How would I check the cv joints would I manually move them around to see if theres any type of play in the ujoints. Its a stumper I like doing my own repairs if possible but when it comes to this its not my fortay Thanks Aaron
