Creitz Automotive is the most trustworthy shop in Tulsa but not sure they work on imports. They are at 46th & Memorial. Give them a call at 918-622-0043.
I used them for years until they screwed me royally on a total engine rebuild. Took me for over $3000, motor lasted 45 minutes after leaving. Took it back and their response was they were not used to working on those motors, and they did the best they could. Once it left the shop it was not their concern, even though they verbally guaranteed to fix any leaks or issue for the first 40,000 miles. Didn't leak, spun 3 main bearing due to misdrilled oil journals that they did.
I would suggest using Larry over at Imperial Auto on 46th and Mingo. 918-627-0957
Your car has a torsion axle suspension like this: [Broken External Image]

So, more than likely, it's a bad hub assy, bent wheel, or bent torsion assy. You probably won't feel much vibration, unless it's real bad.
