Are you talking about making it a locked rear end? There are lots of ways
to do this, from installing a spool to welding the spiders together. I've
had cars in the past with welded differentials, and from listening to the
tires slip while turning the car slowly it seems that there is a lot of
stress on the axle shafts. If you have a car that will easily break the
tires loose, then a locked differential probably doesn't matter. If you
have a low-horsepower car then I'm guessing a locked differential would put
more stress in the axles than any other conditions.
