My 4:10's Are Toast!

[GRAYPNY]

Well I have been fearing the worst and it came true today. My gears have been making a clicking sound for quite awhile now and I had a rearend specialist at my dealership take it for a drive today and he said that the gears were bad. It's odd that with him driving the car and me being the passenger I could hear all kinds of noises from the rear that I didn't really notice as the driver. Whining, clicking and and even alittle howling.

My dealership is pretty good about fixing stuff under warranty on modded cars and that's why I bought there. They are going to see what they can do for me under warranty because I have aftermarket 4:10 FRPP gears and they weren't installed by the dealership.

The tech who has been working on Fords for 40 years said that Ford was getting their gears from China and that they were good for about 12,000 miles before the hardening wore off the ring and pinion. He said he has replaced lots of Explorer 8.8 rear gears.

They are going to try and find another set of 4:10's for me but I might go with a set of 3:73's for something different and alittle better gas mileage. If they aren't going to cover the gears under warranty I will probably opt to put the stock 3:55 back in. I'm just hoping at this point not to pay any labor at $99 per hour. OUCH~

That sux. I wasn't aware the gears from Ford were getting that bad.

ive got about 15k on my FRPP 4.10s with no issue. Perhaps you had the FRPP ones that the part number ended in M? if so those are motive gears and are junk. the ones that end in A are the Ford OEM Gears and will last for a while.

sorry to hear about your prob and good luck getting it covered under warranty!

For once I cannot agree with you. Motive gears are not junk and I have had no problem with mine. I do not believe there is such a thing as a Ron bullet proof part!

there definately is no ron bullit proof part haha. i did break my 4.10s, but that was because i bent the carrier. the gears themselves were ok except for an abnormal wear pattern because of the carrier being out of whack

Mine ended with M. I don't think the installer was quite as good as I was lead to believe and now I am going to put the 3:55 gears back in and pay lots of money to have it done right.

The shop that put them in only had a 6 month warranty on their install and since I didn't even buy the gears through them I thought I was getting a deal.

Remember to adjust your tune for the 3.55 gears! No? You going to be hating it back at 3.55 gears. I think I'll slap in some 4.10s just to rub it in your face! :O
