Although you didn't mention weather the problem began before or after your repair work, your probably suffering from the infamous " Twin I-Beam Suspension Syndrome" (Ok, I made the name up but the rest is true) I actually like the system, however there is one particular sub-part that is arguably under engineered. The Tie rod Bushing (because it comes pressed onto the Tie Rod, I guess rod too). If such is the case, depending on the level of degeneration it can easily cause personal injury to yourself and others. If this is your original tie rod, your more than likely due. 1 way to check is to have someone slowly turn the wheel back & forth (in park) while you kneel down in front of the truck. Look for either tire changing direction before the other one &/or obvious slop in the function of the tie rod bushing junction. Nothing worse than a "Sloppy Function Junction"(sorry). You can also put it up on a rack, grab the driver side tire and wiggle the hell out of it (probably some better terminology out there) to check for slop. Note: I was just thinking, the person you chose to assist you behind the wheel while your kneeling down in front of the truck, should be someone you really trust. Your second choice should be.............. someone you owe money to, alot more than what you have in your wallet at that particular moment. Someone that owes you a lot of money might not be your best choice. A sibling who frequently mumbles under their breath "Mom always liked you best" Pass! Girlfeinds, wives & roommates can all themselves tend to be problematic for reasons nobody likes to be reminded of. Hope this helps! Please post the final outcome & who ya picked. If you don't post again, we'll have to assume you picked the wrong person to assist.
