When I drive over a series of bumps--like a washboarded road or a bunch of potholes and patches in a long section-- at a slow speed, the front right tire hops hard and high, uncontrollably until I slow to a stop. At higher speeds I can feel it but it can be ridden through with only a small vibe through the steering wheel. I did have a warped rotor that I replaced because it did the same thing only when braking between
35-45mph. Now, it does not have any problem when braking but when going over a road as described above at the slow speed.
Does anyone have any ideas on what it could be (experienced the same)? The shocks are original. I don't know too much about testing the larger shocks. When I do the "bouncing" test the truck seems to settle fast without much up/down movement.
Any help is much appreciated.
