'03 GTP 135K mi. I'm about ready to take on my next repair. I've convinced myself I am cable of dropping the subframe and am going to replace the bushings. I haven't had much luck finding options for parts. gmpartsgiant has them, about $75 each front, and $60 each rear. I also found this: DORMAN Part # 924006, for about $30 at rockauto. However, the Dorman part doesn't seem to match GM part numbers and Dorman does not say if it is for front or rear (it looks like front to me????) Has anyone used the Dorman part? Know for CERTAIN if its front or rear? Recommend using or stay away? Thanks in advance to those in-the-know,w/ experience and that share knowledge and experiences!
