My 1500 seemed to want to wander a bit going down the road, sometimes pulling left but usually pulling right. Also my steering wheel was turned about 10 degrees to the left while going straight. I checked air pressure, which was fine, and decided to check the front wheel alignment. Sure enough I had about 3/16" of toe in. I don't know what the official specs are for these things, but all the other Rangers I have owned called for 1/8" to 1/4" toe out. I adjusted to about 1/8" toe out and it feels quite a bit more stable. It also straightened out the steering wheel to almost perfect in the middle.
