I have a 2002 325ci,was wondering what it might cost repairing rear differential on 2002 BMW 325Ci

I hear a loud humming noise from underneath, sounds like from the rear . Which leads me to believe I need my rear differential replaced!

DEPENDS WHERE YOU TAKE IT. BUT I HAD MINE REPAIRED FOR ABOUT $750 AND THAT WAS INCLUDING LABOR. WHEN IT GOES IT GOES SO GET IT REPLACED BEFORE YOU'RE STUCK. AND YOU KNOW THAT HAPPENS AT THE WORST POSSIBLE TIME.
HARD TO SAY UNTIL ITS INSP.BUT SOUNDS LIKE JUST BEARINGS WHICH IS ABOUT 600.00 IF GEARS ARE NEEDED ITS APPROX 1200.00
Good to go, just curious with the worst case seniro. Thank you!
