I bought a slightly used Rubi JKU, it has 12K miles. Coil over setup and the last 7K miles with 40X15.50X20" Toyos on 12 wide rims and 1 inch spacers.
I know its a little over the top and isn't going to drive like it has 35s or even 37's, but it is what it is and the 40's sure look good. My crude measurements using an iPhone roughly showed 1.5 to 1.9 deg. neg. iPhone isn't perfectly flat with the side button and made it a little worse even though I pushed on it. Its visually noticeable compared to the drivers side, especially to me. Tires are wearing great. Well tonight I pulled the stock ball joints and the upper was frozen solid and I don't know if it should be that way from its design. The bottom was easily moveable with one finger and was well broke in and loose. However, I couldn't find any vertical slop in it even though it was loose. Im a little older and the old stuff I use to work on, well parts didn't get changed unless they were obviously "shot."
Anyway, Im wondering if that plastic bushing in the lower showed more slop with the leverage of the Jeep on it or if its not that bad.
I can't find any tweaks in the C's or the housing. It drives pretty well all considering, but at times it will take a good little hunt usually to the right or passenger side direction and it seems to be that passenger front tire feeling a little loose and it by itself hunting on troughed out asphalt. Interstate at 70ish mph it seems fine and runs pretty straight. Im hoping that lower ball joint is wore and I can get some post camber back and lose that single tire hunt.
Im just wondering if a new set of Poly Ball joints will get rid at least a bit of the negative camber or should I get a set of 1 deg positive offset Moogs?
