    Upgrading rear end in \'98 2wd pickup

    has anyone thought about how to or actually done this? Upgrading the rear end in a '98 2wd 1/2t pickup to a 14bsf??? or any beefier axle for that matter? I dont know much about 2wd IFS crap /forums/images/graemlins/eek.gif.

    Im wondering how you handled the lug pattern change. Did you get custom axle shafts w/5lug and change the brake system? or did you use adapters? do they make 6/8lug to 5lug??? or did you upgrade to 8lug allround?? how did the fronted get converted? are 3/4ton and 1/2ton hubs swapable?


    thanks /forums/images/graemlins/confused.gif

    First of all, I think you put this in the wrong forum. Not that I care, but you'll get a more appropriate audience in the "IFS and new sheel metal" forum - I'm guessing that's where you meant to post this.

    As for answering the question... /forums/images/graemlins/thinking.gif...you do know that the 14 bolt SF comes in both 6 lug and 8 lug, correct? I know that doesn't help you much because your 2wd is 5 lug. How about looking under a 3/4 ton 2wd pickup. That should have the 14 bolt SF, but I'm not sure whether those run 5 or 6 lugs. It might also be a possibility that the knuckles from the rear axle donor truck will work on your 1/2 ton....but I'm not sure on that, I'll have to do some checking.

    You can try to find a 14 bolt sf out of an early 90's 454 SS. Or maybe buy just the axle shafts? Not sure of the measurents, though, and the 4x4 versions of the 14 sf are quite wide.

    Get the wheels, front rotors, and rear end from an 88-98 6-lug C2500 (light 3/4-ton 2wd). That's all there is to it /forums/images/graemlins/thumb.gif

    If you are talking about 5 lug axles, 2wd then find a 454 SS truck. They had the 14B sf I did this to a guy's truck. His was a 94 1/2 ton 2wd. It bolted right in. You might need a trick U joint. I used the driveshaft from the 454 SS. hope this helps.
