I imagine everyone with the stock caged lower is going to need replace their bushings sooner than later. Others have done this by unscrewing the tribar (left hand threads). I tried this method but no way it would come apart even with excessive heat. This is the solution my friend/machinist brett at Nimmo Machine came up with. He is a genius, I really like how by removing three bolts I can insert new ones if needed again. He said the poly bushing material should be able to pushed in by hand. If it gives you trouble, two fender washers, a nut and a long bolt could be used to pull it into the hole. He torqued the bolts into his inserts to 40 ft lbs without loctite on the threads so I could remove them if needed. He said the rubber held the insert from turning when he tightened them. He did put a drop of penetrating loctite externally. He also made witness lines so I can verify they don't loosen.
It required drilling out the original pins.
I found the poly bushing material I used from a previous post on svtperformance. Do not use silicone as others have found out. It was said silicone cuts much easier. you don't want bushings that cut easily.
