thanks for your reply,I have one side done with a brake cylinder hone.It fits well with a firm thumb push and no play up or down.It just concerned me that so mucn material had to be removed.I read in my service manual that the 1/2 ton trucks use a bushing that is machined to finish size,no reaming required.Is the system used on the larger trucks better,stronger? Or are us larger truck owners just being discriminated against????
