whats causing this

ok then what qualifies as a qualified shop...

Nobody here can answer that unless they live say, within 10-20 miles of you

NONE of the "big name" stores, Aamco, Midas, Sears, etc, are worth your time. What you want is a local independent shop that's been in business, preferably more than 20 years, and you can actually find local people who have traded there with good feelings.
