I have a 1986 standard bed (converted to Custom Cab) 4wd, manual tranny and 346,000 miles. I'm the original owner, and this truck is still my daily driver.
It has developed a bad clunk (sometimes clunk-clunk) when hitting even small bumps. It clunks when the front wheels hit a crack in the road or a bump, but the sound seems to come from the middle to rear of the truck. It's a "heavy" sound and not a clink or rattle. The truck steers, brakes, corners, accelerates and stops just fine, so I can't feel any problem anywhere in the driving performance.
I've spent hours under the truck with drop light, hammer and big screwdriver hitting and prying everything metal that looks like it can take it. I've replaced all 4 shocks and the rear spring rear bushings with no relief. I can't find the clunk and I'm almost resigned to waiting until some big piece of metal falls out.
Has anyone had a clunk like this develop? Any hints as to what people have found or had to replace would be a big help. Thanks!
