I installed Slee's caster plates and J springs. I have a pretty nasty vibration now. What I'm wondering is if anyone has done the same and not had a vibration? I'm thinking I might need to add a 1-1.5" spacer to compensate for the caster plates. Anybody have any spring spacers they want to get rid of? When I talked to Ben at Slee he said I'd be good with a light rig with Js and the plates. I'm pretty light as in stock other than the Js, L shocks, and caster plates. I still have the Michelins and running boards I'm really not wanting to add a CV front driveshaft to eliminate the vibration but will if I have too. Also, anyone know off hand what shims I'd need to run to run Aisan hubs and go 2wd? They go between the hub and the axle c-clip correct? This could buy me some time while I figure out what to do with the spacer for the spring.
