My 2000 Ram 1500 started pulling to the left after replacing both tie rod ends and the lower ball joint on the left side. Alignment was performed. The pull is constant and the steering wheel cocks to the left as well. When I hit the brakes, the steering wheel straightens up and the pull goes away. It will stay straight for a random amount of time (usually until I hit a bump or turn left) then suddenly it's pulling left again. It's a used vehicle I recently bought: I noticed the right brake hose was new so on a lark I replaced the left brake hose which looked original - it was probably a good idea to replace it, but it didn't help the problem. I'm considering replacing the caliper next but it strikes me as odd that the steering stays straight for a little while with no brake applied. I'd figure a bad caliper would always pull no matter what, and the steering would only straighten because of equal pressure on both rotors. Something in the steering mechanism itself perhaps? Sadly, I'm not experienced in that realm. Side note: It does make a nice bad-power-steering-hum during full turns in either direction - say, when pulling into a parking spot (especially when it's cold). I figured I'd run it by you guys before I spend next weekend replacing things and scratching a hole in my head. Thanks in advance!
