Re: Slight Vibration
I had a vibration in my ute - I don't think I felt it through the seat that much though, it was more something I could hear and feel through the foot-rest quite well when I put my foot firmly on it (and through the gear lever too from memory).
Anyway, I searched around to try and figure out the best wheel place to take it to and settled on one place to try - they did a wheel balance and rotation and most importantly, an alignment (castor/camber too - not just toe). A couple of castor-shims were required, but they got it spot-on - car's been perfect ever since and handles better than ever at high speed.
The point being, that wheel place (the local Tyre Power franchise) said that these cars were particularly 'hard' to get the wheel alignment spot-on and most places don't seem to do it properly (I dunno if he meant XRs or Falcons in general or just AU series Falcons), but anyway, I saw another bloke from interstate had his XR in there a while back and said that all the places he'd been to so far hadn't been able to solve the problem, but the guys there were confident they'd get it right for him and I believe they did but I don't know for sure how it turned out.
Anyway, the moral of the long-winded story is try a few different places, just cause one or two places can't get it right for you doesn't mean you should eliminate alignment etc. as the problem, you may just need to find a place that really knows their stuff for your sort of car.
