Let me vent. My 91 300te 4matic is making the most irritating squeak from the passenger side wheel, turning the steering wheel in either direction creates a terrible squeak, if I hit bumps in the road I get a very minor squeak.
My idler arm bushings are brand new, my sway bar bushings are brand new, all boots on the steering linkages are newish and intact with no tears or oily spots. The shocks and tower bushings are newish (3yrs).
The control arm bushings are old but since the sound is 95% associated with turning I suspect the lower ball joint - but it is newish (3yrs), shows no signs of boot damage...
When I am under the car, the noise from turning the steering appears to be coming from the lower ball joint, I suppose I should replace the lower ball joint but I am not positive that is it...
I have tried pulling back the boot and injecting oil to see if the sound will temporarily go away but no positive results yet.
Ayayayayay!
