I am new here and I have a very perplexing problem. It all started when I hit a full grown groundhog, or something its size, at 40mph on the right front wheel. The impact was so severe I almost pulled over to inspect for obvious damage, but all seemed well in the moments following. Fast forward several months and my dad pointed out outer tire wear and recommended I do an alignment. I did this and the car handled better, especially after new front tires. I assumed the issue fixed, until a few more months went by. The car started to pull to the right as it did before, and so I did another alignment and that fixed the pull. A couple months later it was pulling again, and this time I aligned it and rotated the tires front and back. This time there was no difference at all, still pulling to the right. Three weeks or less from this last alignment, a straight tire is worn enough to need replacement. I don't know what to do, and I have checked everything I can. I checked for tie rod play and found none. I straightedge checked the strut rod and it appears straight. The bushings all seem to be in good shape. I am at my wit's end, and this is my only car. I will soon need a new tire, but I am not going to do that until the pull is fixed. Any suggestions are greatly appreciated.
