The $1,000.00 alignment
So, after dumping a grand into this thing, I took the 4Runner to a new shop in town claiming to be Toyota specialists. i got a good impression from the owner and felt good that his one employee just retired from Toyota after 27yrs. He assured me that he would know for sure the problem before calling me about the truck. He called me about 1.5hrs later and said I had a Caster bolt that had worked it's way loose. He said it appeared that know one changed the caster during the previous two alignments, therefore no one noticed the loose bolt. Glad the truck seems to be fixed, but 3 months without the Runner and 1k spent, I'm still annoyed.
