M1008 rear carrier

[wayne461]

Gentlemen, I'd like to change out the carrier and ring and pinion to 3.73 so the truck is a little more highway friendly. Has anyone done this?

I have, my front end was making noises and found half the rings bolts sheared off and at the bottom of the pan. If I remember correctly it was about 1600 clams with all new internals, front and rear. I did pick up some speed, about 10 mph before the engine said not to go faster. I really do not like pushing engines, so was happy with that. I have not spent enough time driving her to say what type of mileage she is getting now.

Well I bought this truck sight unseen like a lot of us do,and it turned ou that the front axle was toast, so I picked up an axle for $400.00 in Albany. It's a 3.73 gear ratio which is perfect for highway driving. Just wondering if anyone else has changed their ratio to 3.73.

I have and it worked great, I also installed a 700R4 in my M1010 and it was much better.

I put a 700R4 in the M1031 I should have never sold. It worked out well but I never trusted it really.

Did you have to replace the rear carrier? This truck originally had 4.56 gears, but someone put 4.10's in it. I have no idea why, there isn't much difference between the two.

Good eye. But why does that matter?
