bushings and links
I dig your prodject....... my 2cents ....It is true that rubber / polly bushings dont hold up on 4 link susp. with more than 10inc. of travel and on an opposed or triangulated 4 link they realy wont last. Its also true that rubber bushings offer a softer and quieter ride... with that I think you have to ask yourself, what kind of a suspention am I gonna build, how much movement will it have at the axle and what is the degree of deflextion on the joint... Heck, last year in MOAB I lost track of how many broken RE joints and JJ I saw... Polly is crap in my opinion no matter what your using it on eccept a race car... Rubber joints are good up to about 10 degrees of deflection and after that they go to crapp, and the faster you drive when the suspention is flexed and the rubber joint is maxxed the fast they go away ... Heck, everything has to give, even your shock mounts... What joints should you run ???? The best ones you can afford ... should you use oversized hiems ??? only if you cant afford a good sphyrical joint, and then use a rubber bushing at the axle and the heim at the frame. Remember, heims aren't designed to take a side load, everything wares out, rubber has to be replaced, and sphyrical joints will have to be rebuilt........
