[DeTomaso] Suspension bushings squeaking

Sun Mar 14 23:30:15 EDT 2021

Mike,

You don’t lube rubber bushings. Oils will cause the rubber to deteriorate. 

It’s possible your bushings would come apart eventually if they were lubed but that likely wouldn’t cause squeaking. Also, you said that your suspension has been squeaking ever since the work was done.  So I am calling ‘total BS’ on the theory that they separated on day one. 

You keep ignoring the far more likely suggestion, that the sway bar bushings are the culprit? Do you have poly sway bar bushings?

On the other end, there is a larger ring (the outer sleeve)and rubber, with the rubber against the mount. During suspension movement, nothing rotates. That is, nothing is sliding against anything else. Instead, the rubber in between the inner and outer sleeves distorts.

If you make the mistake of tightening everything with the suspension hanging free, it then distorts considerably when the car is set on the ground, consuming much of the available movement.  Further suspension movement then overwhelms the rubber and leads to premature failure.
