Buick Roadmaster Problem

Visitor, 1996 Buick Roadmaster, 25,000 mi
This Roadmaster is always garaged with 25,000 original miles & original owners still has it. Went to Monroe for a oil change came out with a $700.00 charge for idler/piman arm & they said my wheel bearings were loose & the wheels could fall off. I hope that i wasnt taken for all the work it needed with only 25,00 miles on it.
Monroe muffler went in for a simple oil chang came out with a $700.00 bill for this & a idler arm.
