They arent specific, both the ball joints for steel arms and aluminum arms fit in it, the only other part# is the tribeca ball joint which is huge. I talked to whiteline and they've heard of the issue a few times over the years and had no fix for it, seems to be a problem with the knuckle castings. I wanted to do new knuckles, bearings and hubs but i didnt want to do them now lol. Ill set money aside as that will run me 3-400 bucks.
you dont have a local salvage yard? knuckles run like $25 around here with good bearings
Why should we be paying to keep guy's like Chris Watts and Michael Glance alive?
