how much to put in 3.73 or 4.10 rear end?

[airbox]

anybody done it. how much are parts / labor.

 

[sk1er17]

you have an '03 SOHC and dont even have 3.73's already? Some SOHC's even come with 4.10's stock.

..mine did

I want to do the same but it seems the normal price is more than $1000.00. Don't bother with the 3.73's just go ahead and get the 4.10's, and for the amount of money you'll spend...go ahead and get a good locker.
What i'm wanting to do is find a 4.10 rear end out of a 2nd gen, and a 4.10 front diff out of a 1st so I can get the lower gears and convert to rear disks all in "one" step. And that would be MUCH cheaper than installing new gears. That's the plan at lease

To swap out gears is going to cost you about 375 in labor. per axel

good luck on finding a front diff from a 1st gen with 4.10s stock....from what i hear they are EXTREMELY rare; special order only....although i have seen one of two that were aftermarket here and there.

I never heard of EOM 4:10s in and Explorer only in the 4FX Ranger (I may be wrong). Yeh, expect to pay $350 for gears, $100 install kits, $300-$400 per axle for installation. Its not Rocket Science but if you screw it up it costs a lot of time and money. Go with as much gear as you can 410+. My favorite was 4:56s w/33 tires.

I know they are rare....havent found one yet. I was thikning the other night though that if I were to go ahead and do my gear/brake upgade (3.73 most likely) plan ,I could easily keep my current axles and use them as a "practice" tool. So that some time in the future I could go ahead and do the gears myself. Yes I know alot of special gagues are needed...my father is a tool maker though and has a butt load of gagues, calipers, magnetic stands etc. I doubt there is a gague that he woudln't have. Just an idea, I just don't like the sound of spending 300-400 dollars just in labor...and would like to know how anyway.

Explorer SOHC limited slip tow packages came with 4.10; mine were stock in my '99.

I've still got my ring and pinions for sale if you want 4.10. I'll split them and take $85 + shipping for the rears if that's all you want.

I had a Mustang shop do my rear gear swap. I supplied the parts, and they charged me $150 labor.

it seems as though there is a huge regional difference in gear install labor costs. most shops around here charge around $150-175 for solid axle and $200 for IFS/TTB on an install.
