I dont really care how it can be done. The cheaper the better.
If all I have to do is weld the spider gears, that seams like the cheapest way.
I just want it to hold up. It's my daily driver.
All I need it to do is get me through the soft stuff. It's a b*tch with only one wheel spinning sometimes.
When I buy a new daily driver, I'm going to pre-run the hell out it. Long travel, V-8, take off fenders and bed, roll cage and what not.
