Default 8.8. weld it or run the factory trac lock?

my axle seal in my xj is leaking and rather than put money into it i'm going to upgrade to a 8.8. the local junkyard has about half a million exlplorers and i'm sure i have my choice of any gear ratio, disc or drum, and open or factory l/s

it's a xj daily driver on 36's. currently welded and doing fine. i don't want to not weld my rear and have it screw me over from doing an obsticle by not locking both my rear tires.

The one I have has a mini spool in it and does real well so far. I'm just trying to figure out how to get the new disk breaks hooked up.

you can rebuild the trac lock and change the pattern of steel and fiber disks to make it lock up tighter. also you can use a ford lightning preload spring to make it tighter also.

anytime you weld the spider gears in a diff you change the metalurgical properties of the metal. After you apply that much heat to it you weaken it and give it a tendancy to break under heavy load. Ive seen the diff carriers break after welding and also you have to watch the spatter amount that ends up in the axle. Get a mini spool that way your not putting any heat to your components and achieving the same desired outcome and its safer.
