I have a "87 F250. When putting it into gear there is a "clunk" sound. I presumed u-joint(s) but upon inspection the tech?mechanic said rear end. The pinion is a little loose but he said it shouldn't be a problem. It sounds like it is a problem to me! So what do you guys think? He also said if has posi it could be something to do with that... I don't think it has posi.

And does anyone have a simple way to by-pass the RABS? When I drive the warning light comes on. After I park it goes out and doesn't always come backon for a few days. I'm thinking time to by-pass...
