Well I am back. I went ahead and wrote the check (urgh...) and had some much needed work I was going to do on my own but it is too cold in Ohio. I had all control arms replaced and the drive side upper and lower replaced plus a very worn knuckle in the rear. Had the CV pulled and inspected and then differential fluid replaced. Then had a front end alignment and all tires rebalanced. There was no sign of wear in the CV and the all the other components replaced really makes for a stable ride. Much quieter too. But I STILL have that annoying wiggle at 65+mph. I feel it in the seat not the steering wheel and it feels like I am sitting on a cheap vibrating message pad. The mechanic is ford certified who I know very well and trust and I got to see the before and after.
I am stumped. I have less than a year old replacement struts and shocks (done before the wiggle started). Now where do I go from hear. The rims are even less than two years old (purchased new). What is left? Out of round rim, separated tire belt?
