Hi. Sorry to but in. Ive got the same problem with my quad. I just picked it up exactly 3 1/2 hrs ago. It needs valve lash adjustments, and the issue up front. BOTH my front tires are tucking in at the bottom and popping out at the top AND my right side front drive shaft is popped off, not broken though needs the new retainer. The bike looks like an 80's cutlass lowrider on hydraulics lifted up all the way.........that bad. I believe all 4 ball joints quit at the same time.
