Try taking it to a Pep Boys or similar chain auto repair shop and see what their response is if it needs work!
My concern is finding a mechanic that can or would work on a FF axle if it was broken and needed repairs. Sure a good 4x4 Shop that is NOT brand locked would do fine with it but, a dealership or chain is unlikely to have someone that is capable of doing a proper repair.
My local off-road shop is great if you own a Jeep but, they will NOT TOUCH a 4x4 of any different flavor. That leaves me with working with the one Independent mechanic locally that does good work. 100's of miles away from home, how do I find someone to fix a FF axle that is 'broken'?
