Ok gang, so like I said, I wrecked my tweaked 300HP 1996 850 TLA and went out and replaced it with a 1997 850R... sweet! Uh... Using cell phones while driving really can cause an accident... Yikes, hard way to learn.

.....
I'm working through the R getting all the mods in place and making sure things are sound and the way they should be.... Here's the rub... or should I say shudder.

As the car comes to a stop, by using the brakes:-), at about 5-10 MPH and lower there is a deep vibration and shudder in the frame. At first I thought the clutch wasn't disengaging, then I was thinking maybe it's a rotor... but now I'm thinking that it's a rouge control arm bushing.

So has anyone solved one of these yet? If it is a control arm bushing, the parts are cheap, but how hard is it to fix and does one have to have the car aligned after replacing them? I assume that it would be best to do all four at once?

Thanks in advance.
