| Description of the problem | While starting from a dead stop noticed a rumbling sound coming from the rear end. I had the rear differential fluid replaced, u-joints checked, and brakes inspected. (have had this done 3 times in the last 18 months at a cost of several hundred dollars)i mentioned this problem during a casual conversation with a friend who happened to be a retired ford mechanic. He told me that while he was with ford as a mechanic he replaced or rebuilt numerous rear slip differentials, and that it was a major problem especially with the 2004 f-150, and that i should investigate it further. I went on-line and found many many complaints about the 2004 f-150 regarding rear slip differential with very expensive repair problems. Obviously ford has known about this problem for a very long time, and has done nothing about except to offer lame excuses and charge exorbitant prices for repairs. I am concerned about the rear end locking up at highway speed and causing a fatal accident. Why hasn't a recall been required? |
