Hi, new to this forum and already have an issue. I think this is going to be hard to describe, but I will try. I have a new to me 97 4x4 V6 Ext. cab with 50000 miles and the leaf springs are S shaped pretty bad. Negative arch in front of the wheels with a positive arch in the rear. When driving on the seriously potholed roads down here I get what is kinda like a bucking but not up and down, it more of a short forward lunge and a little like wheel hop (not going fast or spinning the tires either). Anybody have any idea what I am talking about or experienced it too? I am wondering if this is a result of the worn out springs, shocks, a combination or something totally different. Would an AAL straighten out the springs temporarily? Planning on lifting it early next year, just need to get by for now. Any input would be appreciated.
