Thanks for the tips guys, I will check them out. I figure I might as well replace the shocks since I plan on keeping the truck. I called auto parts and priced shocks. I was told for the heaver trucks they use a new one that is oil filled (like the old ones but better) They are suppose to last longer than gas with a heavy engine. They are $50 each. The HD gas one was over $60. Any thoughts, buying shocks is like buying tires, you want the one that fits your needs, and since this only the second time in my life for shocks I want the right ones.
