hack n tap

[cbrazor1]

has any one installed the rubicon express sye kit is this a good sye

DON'T DO IT!!! The regular SYE kits with the new shafts are cheap enough to completely avoid this headache.

[TJ Clay]

What is the headache? Unless you're running alot of horsepower or 37s or something i doubt if you need the bigger shaft and you don't have to open the Tcase. What are the drawbacks to this SYE?

What are the drawbacks to this SYE?

The hole has to be PERFECTLY centered before it's tapped. If it's not, really bad stuff happens. You're also reusing the stock shaft and weakening it by drilling a hole through it. It's a difference of like $50 and it's well worth it for the hardened shaft even if it involves taking off the t-case cover. Besides, you can gain some inches of driveshaft with the replaced output shaft.

But, to each their own. I'm just not a fan of hack n' tap.

I'm not a fan either, but I'm wondering what's taking Allen so long to chime in. I know he has it and hasn't had any trouble with it.

swbooking... where are you?!?!?! :confused:

"less Filling!"

[TJ Clay]

I don't know why the hole would have to perfectly centered. The flange that the driveshaft mounts to slides onto the spline of the shaft, the hole is just for the bolt that holds the flange on. I'm not sold on getting one either but for someone that doesn't want to open up their Tcase it could be a good option and don't all SYE's have a hole in the end?

I had never heard of the Hack N Tap but was checking it out and found this page. It has good info and some pics.

Very easy install. Not hard to get the hole centered. Cutting the output is easy. Just lift your jeep, remove DS, start engine, put tranny in reverse to let the shaft spin at idle, use a cut off wheel on an angle grinder and cut at your marks. Very simple. It is a good kit for someone that doesn't want to spend a lot of money.

You got more balls than I do. If any of you do this, please make sure you have a buddy in the cab with their foot firmly planted on the brake pedal while you are under a running Jeep... in gear. **shiver**

No driveshaft though... it's not like it would "take off" on you.

Pull my head out? That's a bit rude.

I know my Jeep has 2 driveshafts. How many does your have? The OP is free to do whatever he pleases. He asked for opinions, I offered mine. Apparently mine is wrong.

[Kodiak Spirit]

I'll chime in; The replacement shaft in most fixed yoke kits is stronger than the stock shaft, in some cases eliminates needle bearings that can go bad, and every time they require you to "crack the case" you get a chance to inspect the guts and fix stuff before things go wrong. I would recommend looking at the parts list before you crack the case and replace stuff that may have worn more than you like while the case is on the bench.

and it really seems crazy to do this yerself, but it really isn't that bad. I did it, you can do it. :2:

[Materdaddy]

Not to scare you too much, but see what can happen if you do end up with a bent transfer case output shaft (non-HD versions are more likely to bend).

Again, read the disclaimer on that thread... that JF vendor has sold many hack-n-tap kits and have no other reports of this type of failure, but it was good enough for me to spend the dough on a real SYE kit.
