Consumer Description

Front differential needing completely replaced at 44,000 miles. Might need a transfer case replacement as well. Original quote of $8,300 and if the transfer case is needing replaced, another $8,000-$10,000 job. I have done research online that a lot of other people with X7's are having this issue. Autobahn BMW in Fort Worth, Texas confirmed the issue and that it needs complete replacement done. There were no warnings, no lights on the dash, and nothing that would indicate there was an issue until leaking starting and I could smell the oil burning.
