Have 09 1/2 ton and just put on 20's. Came stock with 18's. When i step on the brake Sometimes get a bad vibration. Any help?? Thanks
:word:This is a very common problem.
Take off your back wheels, you'll have lil o-clips holding on the drum brake covers. Take close clips off. These clips are just to hold the drum cover to the drum brakes itself during factory assembly. These are fine to take off.
Factory rims have a counter bore to miss these, most aftermarket rims do not, thus your rim isn't seated flush & vibrates.
