Message:
my friend is selling his 2000 R/T, and he knows i want the 3.92 rearend. so he said if i want, we can trade rearends before he sells the truck.
i just need to know is there any problem just trading out the whole rear axle? like abs problems, speedo error's, or anything else i should be aware of before starting the trade.

You'll have to get the Speedo recalibrated, because it'll be off. Besides that? Nothing I can think of, should just bolt up. Make sure you replace the U-joint, don't reuse the old one! There are cheap enough.

Uh... you know, it SHOULD match up since they'll be in the same general area, but you may need to do some patching. I don't know, never tried that. It should be close though, since likely they use the same brake systems.

another thing, you may have to change your u bolts and your spring to axle pad. the 8 1/4" rear end has smaller axle tubes than the 9 1/4" used in the R/Ts and also some 2000-01 4.7s with the L.S. rear diff and the bigger rear gears. just something to think about. see ya. oh yeah. 3.92 gears rock!!! you'll love them

I have the 9 1/4 rear end in mine and its not an R/T. kota if your friends rear-end is 9 1/4" as well there should be no problem with it fitting in yours...

Just curious, if you have a 3.92 ratio, but you
don't own a R/T, is the rear end going to be a
9 1/4 or can the same gears go into an 8 1/4
(like in my case with the '00 Quad-Cab)?
Thanks, Al

I'm a little confused because I'm not sure what your truck is(year and motor) but my son just got rid of a '99 R/T and it had the small rear end. The 4.7s have the larger rear end. If the Y2K R/T is the same as yours then the swap is a cinch. Speedo is on the housing reading the ring gear revs and will be correct. Abs SHOULD be the same. All brake plumbing should match up but a quick visual will tell you for sure.
I put 3.92s in mine and now I wonder how I ever lived without them before.
