I recently developed a vibration at 40-50 MPH. It is worse when I am braking to slow down and will continue to vibrate until I hit 15 MPH while braking. Otherwise, the only time I feel it is between 40-50.
I recently put new tires on and had it rebalanced twice. The first time was because highway speed vibrations indicative of wheel balance problems. The second time was due to this new vibration and it did not help. And the tire tech said they were all in balance...but he pulled all the weights and re-did it anyhow.
If the tires were out of round I would think the vibration would be there at various speeds, but that is the kind of vibration I am feeling.
I have not looked at the truck to diagnose this issue yet. I plan to crawl under her this weekend. Any tips on what I should look for?
