Hey guys and gals. Just wondering if anyone has had this problem. I have a 97 f111 600 and recently the track keeps coming loose. Upon further inspection I noticed the rear axle has worn a half moon in the slide rail on both sides. So after a while of riding the axle slips back into the grooves and loosens he track. My question is can I weld a patch to cover these up or am I looking at new slide rails.
Thanx in advance.

B
