Use OEM CV joints only. Yes pay the price. Aftermarket will not work. I know after troubleshooting the CV issues (Okay Birfield Joints). I only had a 2" lift and life sucked with my LC being at the suspension shop far more than with me. Not many LC experts period. Especially in the PNW
Have you had any issues with the steering ball joints binding? On mine the limiting factor for travel is that it hangs off the steering rack. And yes i have a diff drop..weird
