Hello All. I'm relatively new here. I used to follow the OS pretty regularly. Lost track of it for a few years. When I came back, it was quite evident that the brains of the operation was gone. Took me a while to find this site.
Anyways, I have a very high frequency vibration that I think is coming from the front end - I'd almost call it grinding rather than vibration. It's pretty subtle, but enough that the wife noticed it (she drives the TB most of the time). Through some troubleshooting, I've found that vibration is present when the truck is driven straight or turning right. I can move the wheel ever so slightly to the left and the vibration stops. I can make the vibration start and stop by weaving right and left within a traffic lane, it takes that little of a change in direction. Right = vibration, left = no vibration.
I should mention that I had the left front end apart several months ago to change the differential seal (thanks to this site and off road TB). The vibration didn't start with this repair, it was fine for few months before it started.
From searching this site and reading a lot of other posts, I'm thinking left front wheel hub. I jacked up both sides and spun the front wheels - no grinding sound. Not that surprising since there is very little load on the bearings with the wheel off the ground. Truck has about 114,000 miles on it. I've done no work on the front end other than the left diff seal. There is quite a bit of squeaking and clunking in the front. Sway bar end links are on the list of things to do.
What do you guys think?
