Truck bouncing when slowing
I have a 99 F150 with 136000 miles on it. I had new tires installed on it a few months ago and the man told me the back rims were bent. I started noticing a vibration in the rear end and when I slowed down the back end would bounce a little as I slowed down through about 40mph. I put new rims on the back today and the vibration is gone but when I slow down it still does the same thing. Could warped Drums cause it to bounce at certain speeds or would it do it all the time? Anyone have any ideas?
