Vibration > 65 mph

Having cured various vibration problems at lower speeds through injector cleaning and replacing EGR valve, PCV valve and the MAP sensor, which made a tremendous improvement and made the ride considerably smoother, I still have a vibration problem above 65 mph. At around 65 70 mph it manifests as a vibration which causes anything in the rear view mirror to appear fuzzy (incidentally side view mirrors are fine), but then in the 70 75 mph it is smoother agian, whilst above 75 mph the vibrations are harshest.


Does the front driveshaft sound a likely culprit given above? I should also mention that I have replaced the tyres and rims over the last few years and numerous balancing and alignments so less inclined to think there is any problem in this area.


Thanks

Re: Vibration > 65 mph

Thanks Benn0,

I should have mentioned in my posting that I have a 2005 WK 5.7 Hemi 4x4, although the Hunter Road-force machine referenced in this TSB would presumably eliminate the tyres and rims from any doubt?

Re: Vibration > 65 mph

I have the tyres and rims road force balanced and although two tyres needed adjustment the vibrations persist. Any ideas welcome
