Ok, so this is a far fetched theory I know little about, so take it easy on me.
Is ti possible to weld the gears in the 10 spline 3rd member? Kind of like a locker?
I know it is done quite a bit in yota's and so forth.
I am not an aggressive offroader and run 32's MTR tires. Currently I wouldnt mind having the rear traction aid.
My truck sees minimal DD street driving, I do drive it to and from the trail.

I have 24 spline items to go in the rear, but am saving for a detroit locker so that I can do all that stuff at the same time, probably next year.

I figure that since 10 spline diffs are cheap I can carry one (should i need to) and they are easy to replace on the rear.

Anyt thoughts? I understand that is NOT the proper way to do this, I won;t argue that, but wanna know how plausable it is. Would the 24 spline stuff work better for this?
thanks

That's a Lincoln Locker

Also a spool a lot of yota and jeep guys do this it is cheap but will just snop up 10 spline stuff as quick as you put it in. I can't imagine how fowl it would handle either The differance with turning with my rear Arb on, which is essentially a spool, and without is very noticable and off camber or trying to stay a line forget about it

It will be shitty on road. For your use skip the Lincoln Locker and go with a washer lock. It works more like a limited slip. Just as cheap and easier without the welder.

It is basicaly putting in shims and washers until the gears are so tight that they function like a locker. The plus is that the gears slip on the washers before they break the axels. The minus's are that they do not fully lock and it is a bit tedious to get just the right combo of shims and washers to add. The big plus is that you can still sell the diffs when you are done if you put them back the way they were.

Personally I would wait until you get the 24 spline hd units. Welding the diff isn't a prob there is a tutorial on ih8mud about how to do it correctly to minimize the possibility of it failing. But going with the welded rear or the washer option is not what is going to break its the axle shafts. As long as they look like the ones in my series with the axle shaft getting smaller between the splines and the rest of the shaft. I think they are the same in diameter but not in length not 100% tho.

Anyway the previous owner had a true track in the front with out the hd axles and messed up both front inner axle shafts the long side was sheared in two. We have since put Toyota fj 40 axles under the truck so that we could get more re-gearing options as well as locker options. I'm not suggesting that u do and axle swap but I am worried about the amount of axle shafts you might go through.

Just my .02

Welding the diff is really for rigs that get towed to the trail, they suck on-road and are nice off but very hard on axles. My buddy runs a rear spool but it's on a trailered rig, and I wouldn't want to drive around with one. Detroits will give you prolems on snowy icy roads i've heard

If my RRC goes the full trail truck route, it will have a spool rear and detroit front with non-rover axles because it can be trailered(probally a ford 9' and dana 44)

Alrigh guys, found a local toyota guy who is great at welding them. Been doing it for years, knows his stuff, charges cheap.
I'm getting my 24 spline stuff done and swapping it in. I will also purchase a set of spare rear axles to carry with me.
I really have not much to loose. If I see that the truck is snappign axles lef righ and center, I will just order the HD stuff, and still be saving loads of cash.

I don't drive the rig daily, maybe a couple of days a week on the HWY to work, and never in the winter.
Will post in the sprign when I get it done, and take it wheeling.

Have you driven on the road with a spool yet? It pretty much sucks! I have a full spool and it's awsome offroad but on road it will take a toll on your tires, plus it hard on your axles and it sucks when you try to make a sharp turn.

My axle flange bolts constantly come loose, not sure if it's related but be ready to torque on them all the time. If you still have the stock bolts they'll probably shear eventially since I have already sheared a 7/16-20 grade 8 bolt from constantly re-torqueing.

I would recommend to drive someone elses rig around with a spool before you do yours and if you don't mind it go for it. Don't get me wrong, I had to actually try it for myself too before I realized I don't like it but I've decided it's not for me and that's why I'm going to a Lockrite instead.

DUDE, I DON'T drive the truck daily or in the cold months!!!! It sees barely ANY road time aside from 1-2 times a month on the way to the trail, or 1-2 to work on the HWY.

I am going to try it, if I don't like it, I can always go back and re do it.:D

POST: I am not too worried about on road characteristics, when I drive the truck I drive like a grandma and am extremely careful. I am not too worried about wearing out my tires to much, however, I will take your advice on the flange bolts and order a new set to be made at the local brafasco.
Thanks guys!
I will report back, I should be getting it in late march, early april.

The splines are in the gears inside the carrier. You don't need to do anything (at least, that's what I remember).

By the way.... I am not opposed to hacking the mechanical parts of the vehicle, just welded diff is the rock bottom of white trash/redneck engineering. There's so much wrong with a welded 10-spine basket...
If you want to do something sensible for little coin, try cutting brakes. This is as easy as it gets, just as effective as a locked diff, with the only downside of having to do a little more work. As if you had a manual transmission and had to work the clutch, for example.

I agree that welding a 10 spline diff is a bad idea. Why not just save a few bucks up and get a detriot carrier. You should be able to install it in a 10 spline diff (a 24 spline detriot). Im all for Redneck engineering, but the rover drivetrain is not going to like being welded up with stock toothpick axles. You are pretty much wasting your time and your buddies time (when they have to pull your broken POS out of the bush). Gordo.

People are not reading. LEt me rephrase.
I am gettin 24 spline things welded and carrying a spare set of axles(they take very little time to swap when damaged). IF I notice that I am breaking everytime, than I will invest in HD axles. I am still saving about 600-800$ that it would cost me to get the detroit in the truck.

Axleshafts are still of the same diameter, aren't they?
And you are still using a single-pin carrier. It doesn't matter much which diff you're about to weld.
