welded diff

You weld the gears together inside the carrier, apply heat to the gears first to get proper penetration first though.

Ryna,

If you don't like the idea of welding, another way to achieve the same result, is to drop in another pair of spider gears. You'll have to grind them to fit them in, but once in place they will lock the whole center up. Some say it's a safer way than applying heat and welding.

The best way is to buy a minispool , I wouldnt add things to the carries because they can come out and smash crown wheels, make sure you wash out the carrier properly , then with a very high amp welder ,weld as many surface's as you can in the spider gears . You dont weld spider gears to the carrier , since the carrier is cast.

Also visit the wreckers and purchase lots of axles , since you will twist and destroy heaps

Have i missed something? Why would you want to weld the side gears to the carrier? i would have thought the manufacturer had gone to a lot of trouble putting them in there in the first place!!!!!

If you decide to do this, you will need the proper rods to weld the gears with. They are low hydrogen rods, and they are compatable with hardened steel gears.
I would also caution you that the gears are there for a reason...namely to take stress from the axles and allow steering....if u were building a bush buggy...that would be a cheap traction gain, however, if you are thinking it will be easy to turn on hard surfaces, you will be surprised....I owned a 200b once, and i blew the sungears...welded them up, and to get out of the workshop, i had to do a powerslide...it wouldnt turn out any other way. By the time i got home, i was driving on one axle, and the car wouldnt drive up my driveway (or straight up the road). Have a look at ebay if you are looking for a difflock...there are a few cheap ones there at the moment.

when you unlock the front hubs the welded diff is out of action, so it wont do anything on road, only offroad. Also its a little suzuki sierra, and quite a number of the guys in the suzuki club have welded the rear, and find it perfectly driveable on road
