You dont want to do this to a daily driver. It will cause tires to wear very quickly and if you do it on the front it will cause big problems on the road.Also if the weld dosnt hold wich there is a good chance of if you are driving on the street you have chunks of metal floating in your diff and there go your gears. Its only ok for strictly off road rigs because the dirt will allow the tires to slip instead of the diff,and even then it is questionable. I would strongly suggest spending the money for the lockers if it is to remain a daily driver.

Don't weld it like this...

This has got to be one of the dumbest things I've read in a long, long, loooooooooong time.

I agree. Welding spider gears comes up all the time. As Frank is prone to say, do some research on this forum. There are dozens of threads on this and they all say the same thing. Another good point is that if you haven't got the faintest idea of what is involved, you shouldn't do it.

One more point. There is a post here that the author meant well, but had no knowledge of what is involved. Let us all remain silent unless we actually know what we are talking about.

Welding the spider and side gears is effective but not a good idea on a DD. With the axles locked the wheel on the inside of a turn will be forced to turn at the same speed as the outside tire. This will lead to excessive tire wear.

Welding the front will place a tremendous strain on the axleshafts and u-joints. Steering in a tight turn will be difficult at best.

I agree that selectable lockers are expensive. Have you considered a lunchbox locker?

If you can get it to disconnect, yes although it will pull a little to the driver side. But it is still a really poor idea. It will want to go two directions. Straight forward and straight backward. Off road steering will be nill and trying to change the direction of the wheels without moving significant distances will eventually pull the steering box bolts out of the frame.
