Ball Joint Spacers

[Hellz]

i would prolly be looking then at your shocks if it is hitting that hard that it is noticable to you.

anothing thing would be your T bars. have you made adjustments recently?
maybe they need to be cranked a little bit higher.

im running the same UCA on my rig, and im not gentle going over speed bumps. if you need to slow down to go over a speed bump, you shouldnt be driving a 4x4 SUV. anyways, i have no issues that i have noticed with noises from my UCA, or my front end really other than a steering pull issue ( another story)

as for the original question, i have never heard of a ball joint spacer. i wont say there is no such thing, as there might be....
i dont know if i would trust something like that tho on our trucks.
i know our ball joints are HD ones, but even still they fit in there snug with just enough room to fit a nut on the end of the spindle. so adding a spacer in there i think would compromise stability some.i wont even go into throwing off the dynamics of steering with them installed.

maybe someone here has experience with them will chime in... /shrug

personally, i would be looking elsewhere for the cause as that is what i think is going on. to me sounds like too soft of front end shocks. if they are original shocks, with the UCA installed, they are prolly shot.

keep us posted on the outcome tho
