2016 Mini Countryman

This complaint concerns my 2016 Mini Cooper Countryman S, All-Wheel Drive. About four months ago, I began experiencing wobbling and noise when making turns at low speed. I took the vehicle to multiple repair shops for diagnosis. The first shop recommended replacing the clutch pack assembly ($2,626 + tax). The second shop suggested replacing the transfer case (~$2,928 + tax). Based on that, I purchased a used transfer case ($407) and had a third shop install it ($580), but the issue persisted. I then went to a fourth shop, which again insisted it was a transfer case problem. However, since my vehicle is relatively new with low mileage, they recommended reinstalling the original transfer case. After doing so, I noticed only minor improvement, and soon the same wobbling and noise returned. So far, I have spent the following on unsuccessful repairs: $108 diagnostic fee $407 for a compatible used transfer case (purchased from eBay) $580 for the installation of the used transfer case $1,058 to replace the rear differential fluid and reinstall the original transfer case This totals $2,153 in expenses, yet the wobbling and noise issue remains unresolved.
