You might want to be a little more specific on what you expect.

Park it, lock it, forget it.

What I mean to say is, I don't have the money to do 60s yet, what can I do to get buy with my stock dana 44s to make it threw a few trips with out them braking

On road, no problem.

Off road, it can be a big problem.

Steep off camber climbs where most of your weight shifts to one of your rear wheels will result in bent rear axle shaft flanges.

If you bounce much at all while conquering an obstacle, your rear axle housing can flex enough to result in chipped gear teeth.

To run 40s on a stock width front axle, you need 3.5" or less backspacing, and even then, your tires will rub the frame and lower control arms on a full lock turn. So, your unit bearings and ball joints will wear prematurely if you offroad much.

It doesn't really make any sense to build up a stock rear 44 to run 40s when you can buy a bolt-in Currie or Teraflex 60 with 35 spline shafts, starting at around $3500. It makes more sense to sell your 44 and buy the 60 than to buy rear shafts, regear, truss, and/or do a Super44 upgrade to 35 spline shafts. High end aftermarket 60s run closer to $5000 with features like full float, etc.

If you have skills, you can build a junk yard axle for less than $3500, but it won't have the same clearance and plug-and-play features of an aftermarket 60.

Regarding the front 44, if you truss the axle, do chromoly shafts, upgrade ball joints, upgrade to a chromoly tie-rod, etc. you could run 40s for a while. Front bolt-in 60s start at about $7500, but they usually include lockout hubs ($1500), chromoly shafts and tie rods, etc.

If you have skills, you can build a junk yard axle for much less than $7500. However, by the time you do hubs, RCV axle shafts, locker and gears, brackets, etc., it still isn't cheap.

I made the mistake of running 40s on my 2 dr with a 44 rear axle.

I broke my first Rubi locker.

I blew one set of pinion bearings that destroyed the housing and damaged the gears.

I broke another set of gears.

I bent both rear chromoly axle shafts.

So, it cost me:

• labor for gears or locker installs 3x ($1200 labor and $900 for 3 sets of gears and overhaul kits)
• 2 sets of chromoly axle shafts ($1000)
• 1 additional Rubi locker ($600)
• 1 additional rear axle housing ($800)

So, instead of selling my stock rear axle for about $1200-$1500 and buying a 60 for $3500, I spent $4500 on my Rubi rear axle that I could later sell for about $1500 when I bought a barely used Currie 60 for less than $3500.

Hahahaha this is exactly what I was thinking coming into this thread.

Don't take this the wrong way.... you should have bought the axles first. Now you are in a situation where you are going to waste money to run those 40s you have and as PLANMAN said.... you'll end up on a bigger axle anyhow.

I am seeing way too many people trying to run big tires on little axles.... Claiming they are fine. Yet I usually see somewhere where they do acknowledge the fact they are stupid and will upgrade when the time comes... well, when would that time be? My guess... When they are wheeling. Why does that make the person doing it the biggest asshole in the world? Because he/she just ruined everyone else's trip. IDK about where you're at, but just to get to the trail out here costs me a few hundred.... to have that pissed away by "that guy" just sucks and makes me want to punch him for days!

Don't be "that guy!"

My honest suggestion is to put the tires in the shed until you can get proper running gear or sell them.

Thanks got all the input, I will leave 37s on till I have axles!!!!!! What are you guys running for gears with dana 60s and 40s still 5.13 or 5.38??? What lockers arb or Detroit?

TheDirtman

You really needy to be at a 1.75" net bs in order to maintain full steering or run a whole lot of lift and long bumpstops.
