-Spike- said:No problem with the arms. No problem with the tube. I envision problems when the truck weight is supported on the driveshaft, in the u-joints , yoke, and pinion/t-case bearings. Having the yoke or u-joints spinning against immoveable rocks concerns me. I may do a combo, making new arms from .250 wall DOM, re-tubing my bent driveshaft with .125 or .250 tube, and rotating my pinion. I have a spare front 3rd member, so I might try to fit the parts you mentioned above to better oil the pinion bearings. I've never seen them, so I will have to investigate further to better understand what I'll need to do.
The rear arms and driveshaft have always been my biggest worry when crawling over rocks (well, my cat too, but a local muffler shop is confident they can remedy that, so I'm waiting for an excuse) so I'm kind of excited to get this taken care of. What's that saying, 'NO FEAR'?

-Spike- said:Yes, 37's are in my future, but any little bit helps. The tires are a $1000+ upgrade for one inch of clearance, the DC shaft is $450ish, the beefy lower arms are steel cost plus bushings, the pinion adjust is free with the stock shaft if it works and may gain me 3-4" of driveshaft clearance. It's also been my experience that bigger tires just means bigger obstacles, not less breakage. I feel the need to optimize everything, and hopefully spend less time/money fixing stuff I already visited.
Thank goodness the truck is limited to 37's, or I'd be in trouble. It is limited, right? Never mind, I don't want to hear the answer to that.
