2003 Ford Explorer Q&A
2003 Ford Explorer Question: Rear Differential Repair
I just had another front wheel bearing replaced (again) and the mechanic says that he thinks there is a problem with the rear differential, but he can't do it (not a Ford mechanic). He said to take it to Ford, but that the cost might make more sense to get rid of the vehicle. Any idea the price range of rear differential repair/replacement for a vehicle with 67K miles? - Visitor
If the differential needs rebuilding its a 8.3 to 9 hour job depending if its a positraction or not plus parts. But usually when a ring and pinion in the rear end is failing you will hear a howling sound when accelerating or decelerating, So I would call some shops from the directory to find one that rebuilds rear differentials as its still cheaper than replacing the whole vehicle and you can locate a shop here http://repairpal.com/directory?address=02021&car_brand_names=Ford - hemicuda
Would you guess this to be likely less than $1500? I just put over $2500 into the vehicle last year, and while I don't like putting more money into it, I would rather do that since this is all paid off and I don't want yet another car loan right now. But I keep seeing that 2003 was a bad year for Ford drivetrains and don't want to waste anymore.. - jduvel
i would say a rear end for that truck would run you around 500 used - Visitor
It is doubtful, but not impossible to have two nearly indentical failures on the same truck, but it depends on the duty cycle. A truck being operated beyond its' upper load limit, or Gross Vehicle Weight Rating, can impose destructive loads on an axle bearing long before damage occurs to the carrier assmbly. An overlburdened or improperly loaded truck imposes beyond design limits loads on the bearings and that alone can cause bearing faillure. Other factors may include incorrect differential lubricant, an undiagnosed diferential oil leak that allowed the lubricant level to drop below minimum to provide axle bearing lubrication. I was a Ford shop Foreman, and a Master Certified Tech. I begin every repair with an assessment of the causes of the operational concerns, and perform repairs accordingly. I was discussing quality repair yesterday with a junior techand I realized I have not had even one comeback in over ten years. Using the correct diagnostic routine will help direct you to the causes and will lead to a superior fault resolution and is preferred Instead of just replacing the failed parts. This will provide you with long term solutions. First determine if you are actually operating above GVWR, and stop doing it. Verify correct grade and level of differntial lubricant and that you are using the correct tire diameter and pay future attention to weight distribution. - Visitor
I was driving my car tonight and the abs light came on and I heard a whirling sound, more so when I applied the gas. I thought it was related but I don't think so now. The whirling sound continue...
There is a loud roaring sound from the rear end.When on the gas it is loud and off the gas alit...

What does it mean when someone say your differential seals is leaking?
