Hi guys - I know how it is commonly done including Ian’s great video. Is there a reason why not to use bushing grease instead of softsoap?
So you want the bushing NOT to move or rotate ones installed? I assume that is a reason but wanted to ask. Thanks. |

If you get a Powerflex bushing to bind you have done something seriously wrong (IMG:style_emoticons/default/laugh.gif)
@mikey914 that's just it, they are never at 0 preload. If every car was exactly the same weight and at the same height for the life of the car this could be true. But variation in weight (empty vs full fuel tank) and height adjustment means they are always preloaded in some direction. The torsion bar doesn't need a return force by nature they create it when twisted. The rubber bushings are a classic "cost vs performance vs comfort" production car compromise. Race cars use pillow ball, spherical or delrin (or similar materials) for bushings not poly unless some special need arises. Bushing technology has come a long way since the rock hard Weltmeister poly bushings of the 80's and a whole lot further than the rubber compounds used in the 60's and 70's. If you're doing a "correct" restoration sure use rubber If you drive your car and want the best handling with little to no change in nvh there are better options available. |
