Hey guys, I just got a new [well, new to me, lol] 89 RS. Supposedly it has 300k miles on the body but only 36k on the engine. Anyways, when I'm driving, I notice that whenever I give it a little gas and let go, I hear and feel two loud thumps or pops from the rear passenger tire area. I'm wondering if it's a problem with the rear end or not. I'm pretty sure it's not the tranny, the tranny slips once in a while and I can feel that right under my console.

Also I don't think it's getting as much power as it should. I mean even though it's not a V8, when I floor it, it's really pathetic. Literally when I floor it, I'm barely keeping up with normal everyday traffic. Another reason why I think it's the rear, the rear isn't catching all the power it should from the engine. My friend thinks that it sounds like the teeth aren't catching or something.

One more problem, when I'm driving there is a sound coming from the rear. It sounds like I can actually hear the tiresspinning, but it's very loud, it sounds like the tires are about to fly off.


Does anyone know if it is a crappy rear end or not, and where can I pick up a nice one for pretty cheap?

Thanks in advance to anyone who responds.
