Vibration at speed

[Mitch Spiegel]

Experiecing a Vibration at 65mph and above. Tires were recently rebalanced.

Also had Pinion seal replaced recently, could drive shaft be out of phase?

Dealer replaced the entire driveshaft under warranty on my '10 Limited. Said a U-joint was "sticky" and instead of messing with a replacement said the entire driveshaft replacement would be better. It made a huge difference and got rid of vibration that was there from day one.

Mitch,

Early 4X4 Sport Tracs were known to have driveshaft problems. There was a TSB to replace the old steel driveshaft with an aluminum version when vibration was present at speeds above 70 mph.



It's hard to diagnose a vibration since we don't know exactly where you are feeling the vibrations?



The general rule is if you see and feel the vibration is in the steering wheel, then you either have bad front tires or the tires are not properly balanced.



If you feel the vibration in the seat of your pants, then it is probably a bad rear tire, or perhaps a driveshaft or rear tires are out of balance.

+1 on all above...One thing to check- look inside each wheel for caked up mud, etc. This will through off your balanced tires and cause vibration. Also, just the smallest pot hole/bump can through off your balanced tires.

worn out shocks may cause this as well... my 2(where's the "cents" key?)
