My friend complained about shimmys and thump noise on his new PA Buick 13000 miles. I advised it was only tire balance. the buick dealer charged him $40 for balance and told him him he needed new tie rods--under warrantee. This is not an off road hot rod driver but a sedate speed limit 75 + year old. The dealer then charged him $3.98 for disposal fee for the old (new ??) tie rods. He is mad at me and the dealer, and is going back to buying Lincolns. Question: is it ethical or good business to 'mickey mouse' a disposal fee on a warrantee fix. Question: anybody else out there with worn out front suspension on Buicks under 100,000 miles??
