if its rusty get 6 grade 8 9/16" by 4.5" bolts with nuts. a leaf spring and shackle bushing kit 4.2134G from energy suspensions. new U bolts which i got at a spring shop near me. and a few cut off wheels for a grinder. (**optional** several cans of monster incase it turns into a long night) and what you do on the front bushings is litterally slip the grinder in between the spring and the hanger and burn through the stock bushing and cut the bolt. sounds confusing but one you get going youll understand. then i litterally burnd my stock bushings out with a propane torch. my truck has been in western NY its whole life (we salt the roads
) and it took me and 2 buddys 10 hours (not really 10 straight hours) to flip the rear axle, a job that most guys say 2-3 hours took us from 630pm-430am. 110% worth it though.
