49K miles, just replaced front tires in March; need to replace tires again due to bad ball joints, replace ball joints and get wheel alignment. Was given estimate by Firestone for lower ball joint repairs and alignment of $537.60. Called Dealer and being told have to replace control arms, as well, and their charge is $1,047.53. A little assistance, please? Need to pick daughter up from hockey camp Sunday over an hour and half away. Thanks.
