Hey guys, just signed up to the forum. Been around RAMs forever, but have run into an issue that I was hoping someone here could steer me in the right direction. I have Toyo Proxes STIII's on the truck, 22" wheels. I needed two new tires as the front two chewed through the inside edge really badly. Bought two online, took them to local tire store to have mounted balanced and realigned, since I thought that was why they had the inside edge eaten. They called and said the lower ball joints were bad, but could go ahead and put the tires on but would need to bring it back to install control arms with new ball joints then do alignment. Had the truck back for a few days with the new tires and didn't notice anything strange. Took it back to the shop, they replaced both lower control arms which included the new ball joints as an assembly. We did NOT replace upper ones, if that matters or factors into this issue. They did the alignment and I took it home. Truck seemed to pull bad to the right and vibrated badly at high speed. Took it back to shop, re-balanced all four tires and rechecked the alignment. Vibration went away and seemed to be slightly better on alignment.
Here's the odd thing, truck will steer almost perfectly straight on a flat level road, but when you are on a crown or slant it will pull in whatever direction the slant is in. Sometimes rather severely. I took it back to them and complained it never did that before and something was off. They claim it's got to be the alignment and checked it again. Aligned the truck for the 3rd time and it seems to be the same as before. Will drive straight on flat surface but as soon as you are on an angle the steering wheel will turn slightly and pulls in that direction, left or right, doesn't matter. Like I said, I'm replacing the same tires with more of the same and never had the issue. Do you think I should have replaced the upper ball joints at the same time, could that be causing this? I've checked the directional tires, air pressure, all of that is fine. Any ideas what might be causing something like this to go on? Let me know if there are questions or if I left out any details. I appreciate any help at all. It's just very frustrating that the truck drove perfectly prior and now can't get it back to normal. If they can't get it fixed I'll take it to another shop or the dealer, but I've already sunk too much money in it to start over, but if I have to, I will. Thanks!
