This is on moms 97 fzj80. Noticed it this morning, been wondering why the steering was a bit off..........now I know! Notice the large gap between the arm and knuckle what would cause the nuts to back off like this? its only been dealer serviced(so that rule me out the axle tube seals and all felts have been replaced at least once, knuckle bearings from what I recall have not been done. Does the lower arm need to come off to do the wiper seals? or for any other reason? I can't figure out why this happened. I can see no shims or anything on that side, the otherside looks like it has shims or at least a seal. Its been a while sense I have done a 80 knuckle.....so I kinda forget what gets taking apart. Something tell me the dealer has the bottom arm off and didn't torque it up right.....and its worked itself loose. Taking it in this afternoon to get fixed, she was just getting ready to drive 200+ miles friday........told he NO WAY! she can take my UZJ. I am gonna assume the knuckle bearing, tube seal are toast, the bolts/studs prolly need replacement. What do ya all think?
