I brought in my Ford 9" center section (I pulled it out of the car) for a pinion bearing replacement. They called me up the next day stating that everything is bad and they would also have to change the ring and pinion. This unit was not making any noise at all, just the pinion bearing had play. When I asked them how much it would be, they quoted me an outragous price of well over $1000.00. This is for an open 28 spline center section, not a Detroit Locker or Traction Lock unit. When I asked them how much I owe them for the bad news, they want $89.00 for a 15 minute tear down. This is the last time I ever do business with this company. I could get a new Traction Lock from Currie without a core for the same price they want to rebuild my "OPEN" unit.
