When going over bumps, or turning at a sharp radius, I occasionally hear a loud clunking sound out of the front end of my truck. Over the past few weeks, I have also noticed a small shimmy coming from the front end of the truck. Today I passed my dad going down a fairly flat straight road, and he told me that it looks like the truck is leaning more than normal towards the driver's side when driving. Does anyone have any guesses of what this could be? The wheel bearings were checked, and re packed last spring, and nothing is visiably wrong with the steering rack.
