    Dropped off a rock shelf and mangled the front drive shaft. I have a local shop that I'm sure can cut the ends and build me a new one, or should I look for a used one. Can they be built stronger? I know nothing will hold up to the weight of the vehicle but... Is there any way to give it some protection besides bigger tires?

    Just consider this another credit in the drivers education class that everyone takes during the game of life...



    Good luck!

    i'd rather have the driveshaft be the weak link, as opposed to tcase or pinion... IMO might as well stick with stock.

    but, as i've heard said here before, i don't know nothin' about nothin' :)

    I believe the U joint is the most desireable weak link, it's the cheapest part. Not to say that you need weak U joints. I would order up a custom shaft and keep that in mind.

    Oh and Chug, get a new avatar already, it's been like 2 weeks, sheeeesh... :D

    while on the subject of driveshafts, how hard is it to make square-tube shafts? is it as simple as it looks?

    square front shaft here. Piece of cake to make, although I got western with it and milled the yokes square to a light press fit for each end of the tubes. I Then welder her up and took comfort in knowing that it was the one piece in my drive train that will not break.

    I also shimmed the inner tube with sheet metal to take up slack in the tubes and now I can go 45mph with out vibs and the hubs locked.

    Nice pic, that looks pretty sick. So how did you keep the sheetmetal on and is there much slop at all. Shouldn't be too hard to get a boot over that to keep it clean right?

    The sheet metal is the length of the inner tube and is stitch welded on in 3 or 4 places down the length of the tube and also on the ends. The welds are ground flush with the sheet. I think the sheet is 16 GA and there is a shim all on 4 sides. There really isn't any slop at all, when I turn it by hand it makes no clunk sound as it rotates like it did before I shimmed it. Make sure you pack them full of grease, lots of folks put 4 zerks on them and pump them up. Most suggest to fun it the other direction so junk will drain out but I opted to run the other direction to keep the actual slip un-mangled for smooth action. I need to drill some holes in the bottom of the larger tube for stuff to drain but I haven’t been anywhere this summer where it has had an opportunity to fill full of stuff. Some people put shock boots on their's, but I could honestly care less.

    I'll vote for the square tubes as well. They put them on one of the heeps in extreme 4x4 sheered the bolts of but didnt hurt the shaft.
