I have a 1986 Mercedes 190E 2.3. I am getting a really bad creaking sound from my drivers rear suspension by the wheel. I'm 99% sure that it's the lower control arm bushing. Does anyone have a diagram of how I can lubricate or replace this bushing? If not, then the dealership quoted me $50 for the part and $200 for labor. Please help. Thanks all, Scott Chaffin slchaffin@ou.edu
