Intermittent vibration at speed 2WD.
Hi all, I am new to the PowerStroke.Org boards.
The knowledge here seems substantial, so perhaps someone can shed light on my drivetrain issue.
Truck: 2001 F250 Crew Short Bed 2WD 7.3L Auto Trans. 170,000miles
Symptoms: Intermittent wobble, apparently from the front driver's side wheel.
This tire is wearing on the outside edge in a rounding fashion (not a taper).
Vibration starts around 70mph and lasts until about 80mph. Taking a corner at those speeds sets off the vibration (either right or left turn). Vibration tends to continue once traveling straight until either a bump or substantial change in speed. However, no significant vibration at other speeds. No clunking noises.
Friends RV shop checked brakes and the front end. They reported nothing seemed worn or loose.
BTW: The problem is completely, predictably, reproduceable.
Before I start guessing and replacing parts. I thought I would see what you all think. I did not see anything in the forums that matches particularly closely. Of course, I may have missed it too.
Thanks for your guidance!
