I have a 2003 Z-71 silverado extended cab truck. I have never had any problems out of it until now and I am worried. When I put the truck into drive or reverse and attempt to accelerate, the truck makes a slight click noise which can be heard and felt inside the truck. I was worried so I took it to a shop nearby and the guy replaced both of my U joints and said that it was fixed and that was the noise I was hearing. It went away for about 2 weeks and now it is back? He said it wasnt my transmission when I was there but he also said that he fixed it and he didnt. Please help me and is it going to be expensive?
