Hey pill MG42PillBox, NO one said you were an @ss, I look forward to reading other peoples hints and suggestions. That is how you learn, no one person knows it all. I have used a lot of things from this board to help my truck out. I didn't mean to sound rude, If it did i'm sorry
My axles are both stock, It had a posi unit in the rear end when I got the R.C. My good buddy @ Dwight's Place Autobody welded on the gussets and square tubing to the front axle. All I know is never weld the spider gears, we broke axle after axle. I found that something has to give when you are beating things up. I have changed 3 frames in the last 4 years due to bends and cracks. You need a lot of metal to jump these trucks. I also found that the housing is weak where the tubes meet the pumpkin. A good weld around there helps out the most.
