I just bought a 2002 Eldorado ETC from a dealer in Buffalo. 100 miles down the road the rear started squeaking and it is very annoying. I tried spraying all the bushings with no great results. Has anyone else experienced this and what should I be looking for?

Thanks.

As it turned out is was the knuckle bushings on both sides plus the right hub assy. This seems to be a fairly common problem for this year and model. I hope they have re-engineered the part to last a little longer. It sure was a pricy repair.
