[DeTomaso] Removing Poly Bushings

[Thomas Tornblom]

I have Marinos offset poly bushings, which has a round steel insert,  
and it was a fairly tight fit in the bushings. They came with some  
silicone grease which should be applied on the insert/bushing so that  
the bushing can rotate on the insert. The bolt should be tightened so  
that the insert does not rotate on the bolt, only the bushing on the  
insert.

I installed the bushing two years ago, and they are completely silent.

I also installed grease zerks such that I can get grease in between  
the insert and the bushing.

Oh, and the offset bushings didn't make much difference on my car.
