2002 new ring and pinion breakin?
Question:
Just received my wifes 2002 back from the dealer service. Besides replacing the "main timing chain" they replaced the ring and pinion (and about every other part) in the rear end to correct an obnoxious whine at about 65 MPH. Is there anything special you do (don’t do) to break-in a ring and pinion?

Did the replacement ring and pinion parts cure the whine? DS
Response:
The gear set comes matched… i.e., all ready "run in". Relax…. enjoy… — Jim Warman

Yes and no. Fixed the whine I complained about. Created a new one. The first one was between 60-65 MPH with the worst of it at 63. Very noticable. The new whine is not as loud and occurs between 50-55. I don’t know whether to take it back or just forget about it. I’m leaning toward option 2. My wife drives the thing and won’t notice it. Heck she didn’t even notice that most of the winter (in Minnesota) the warm air would only come out of the defroster ducts. That was a bad vacumn hose it turns out. I went through this same "noise in the rear end" business with my Cobra 8 years ago. I think that rear end was opened up three times in 5-6 weeks. Third time was the charm but sure was a PITA for me and the technician I’m sure.

[snip] Interesting result. The reason I asked it because the differential on my ‘02 also whines around 60-65 MPH. My particular Explorer is 2wd and has the 3.73 LS towing option axle. I have a year left on the warranty and I’m now wondering if its worth the trouble to have the dealer mess with it. DS
Response:
Mine do the same whine and they replace the ring and pinion twice with no satisfactory results. After messing with the dealer they are going to replace the whole differential (3.73 LS), drive axle, damper and both wheel axles for a new ones. They explained that Ford acknowledges the problem and they are going to issue a letter about this and they will send to the customers which VIN# are involved.

Response:
Having the rear end replaced again. Not sure what the final part tally will be but do know at least a ring and pinion is going in. Do you need to breakin new gears. I only remember when I did gear swaps on Mustangs years ago, I had to go through some cycle of driving and cool down for a certain amount of time. Also, would it be advisable to replace the differential fluid at a certain number of miles (like a 300-500) after installing the new parts.
Response:
Yes, the new ring and pinion will run hot for some time. Not sure about the number of miles to take it easy, maybe 1000. Try driving down the road, stop, then feel the differential. It will definitely be much hotter than it will be 5000 miles down the road. Change the fluid wouldn’t hurt, but I would ask whoever installed the gears for advice. Ron
