Should i weld my rear end?

I've been thinking if I should weld my rear spider gears (1990 toyota truck, right now IFS hoping to buy axle this week) I don't have the money for a locker right now.

I've heard that with the rear end fully locked it will push on corners and you'll spin out?? That's just what I heard.

I agree some lessons are only learned the hard way by some.

Do you have any idea just how a differential works just why it was needed??

As long as you are on a surface that allows the rear wheels to slip it might last a few hours or so.

It causes excessive tire wear.
When I had a wielded rear it causes hop in turns on the street, But during rain it was great, It stops peg-legging and always wants to stay straight.


I would avoid Lockright and Spartan for V6 diff like the plague, There is just way to much play with big tires and that breaks things and the jerking is really anoying, They might work better in minitrucks.

I had mine welded for several years and did not like it. It hoped, bucked, and chirped the tires whenever turning. Tires on the rear would last 6 months tops. The welds eventually came loose going 65mph on the freeway and I almost lost control of the truck. I was in 5th gear when it came apart and the drivetrain shock caused me to loose 5th gear also.
But it worked great off road!

You'll wear through tires faster, and have lots of tire chirping and hopping around corners. Lunchbox lockers aren't expensive, and work well. Personally I would save my money until I could afford one of those, or a full case locker.

How would a twin traction beam setup help in this situation what so ever?

My opinion is if you can't afford a locker better not plan on SAS right now. If you think a locker is spendy then you haven't really researched the cost of an SAS. Tires aren't cheap either so welding a dif is cheaper initially but cost increases significantly with time.

From what I've seen actually welding a dif to do correctly is quite a process. A broken weld mean replacing the dif. So seems to me that a lunch box locker is much cheaper in the long run.
