i really want one for my wagon. i would weld... but i hear wagons break axels like twigs.

Welding isn't a good idea for the street. Just for fun I worked this out:

 

Assuming the goon has a 30 foot turning circle and is about 4 foot wide (it's actually 50") and has 27" tall tires. (smaller would make these figures even worse.

 

My math says that the outer tire turns at least 13.3 times while the inner one only 9 when turning in a circle. Now if the diff is welded, the inner and outer tires have to turn together so over 4 full wheel turns have to be argued and fought over by the tires. They will stretch slightly and slip suddenly causing a shudder effect similar to wheel hop or axle wrap which puts a sudden overload on the diff. Now the H-190 is fairly tough and can take this longer than the tires which wear, and the axles which will eventually snap.

 

4 turns in a circle would seem like one turn every time you turn a 90 degree corner in town, well close. This adds up to a lot of tire slip.
