Re: First timer with axle questions.
Quote:
For your intended usage either 44 or 10 bolt would be more than fine. The 44 or 10 bolt will handle the weight of your 383 and live with the torque. If you leave the front diff open you will be less likely to snap a stock shaft. If you do go with a limited-slip or locker, upgrade the shafts for sure. I'd wouldn't go past 35" tires with either axle as it will keep the stress on the shafts within reason. Going bigger will require the upgraded shafts for sure. I wheeled my old '75 for a long time on 35's and an open front diff. Beat on it actually with the manual trans. Turned out I broke the 12b rear before the front got any damage at all. The 12b failure wasn't on a trail either. Lost a tooth on the pinion and it got shot out of the cover a block away from my house. Now I will admit in my '91 while it had the 5.3 I did manage to snap an axle shaft 3 times with my D44 8 lug front axle. I am running a Tru-trac up front and it seems to be part of my issue with breakage. The Tru-trac has a tendency to wind up under torque and the auto trans seems to keep the torque applied. Each time I broke I had gone from drive to reverse to back out of a situation. Chromo shafts are on my upgrade list, but the 8.1 project kinda snowballed and killed the budget. Just have to keep my right foot under control until I upgrade.
