front DS strength

Hello -

I've been reading up on hack n tap SYE installations and was planning to do one soon but a conversation I had with a local 4x4 shop guy has me rethinking my course of action. While talking to him, he informed me that he's never heard of someone using a front DS with a H&T, and that they usually have driveshafts made by a local shop (for about $370). I guess my question is - has anyone here ever heard of a front DS breaking while being used as a rear DS? I won't be doing anything too abusive (relatively speaking) in the Jeep - that's what my MTB is for - but I will definitely be four wheeling it and want to insure that I'm making the best choice under the circumstances.

He also mentioned something about H&Ts causing excess vibration in the T case and destroying it, but it sounded like this might have been caused by a crooked "hack" of the tailshaft, and could be avoided if one was cautious and knew what they were doing.

Sorry for yet another SYE thread - but I haven't found this topic addressed specifically. Thanks for any info.

I feel like being helpful -

if you have a 242 the porc sye won't work, and you'll have to use a hack n' tap kit. if you have a 231 you'll be fine.

From what I have seen there are 2 types of driveshafts, a skinny one and a thicker one. Thats what I"ll be using in the rear of mine. By the way. Porc sells custom made CV Driveshafts for $270 shipped to your door. if you think about it it'll cost you $50-$100 for a used driveshaft shipped to you and then you gotta pay another $100-$150 to have it adjusted and balanced. so you're only savin around $70 and you're still stuck with old ujoints..... Just somethin to think about, the new driveshaft might be worth it. I bought the old driveshaft just for a backup

Make your own-- http://www.naxja.org/forum/showthread.php?t=80289&highlight=yoke . It reuses the stock slip yoke cut down, drilled, and tapped instead of the R.E. hack and tap. This saves you ~$80-90 for the output yoke flange (R.E. H.nT.) and ~$40-60 for Spicer part #211229x. Then just bolt up a front prop. shaft and you're good.

Front shafts are easy to find and cheap. If it doesn't work then buy a new one. If it does, you've saved some money.
