check your hubs yet? what days are you off any way? let me know when work for you and ill help you check it out.
with my 521 i could physically shake the wheel with it off the ground it was so bad,but all it needed was grease. spindles were okay.
i work saturday sunday and monday nights. spend tuesdays with kate. so... friday? i live close so i can come to you, instead of having you drive way out north.
if you wanna take a crack at it before, try raising the front end, support it on stands. * you can borrow mine from jake if you need.
once its on the stands and secure, turn the steering wheel back and forth slowly noticing and noises or odd vibrations in the wheel. next check components by simple visual inspection (i.e. bent, broken, loose stuff) and trying to wiggle parts. if something seems loose it has backed itself out and needs to be readjusted or replaced due to wear. i'd be more than willing to help with your valve adjustment too. forgot to give you those feeler gauges at the event. had them in my truck from when i recovered it from work the day before. >_< doh.
