I've scaled back my plans so I will do 2", and hopefully won't need an SYE... But that's good to know the general cost

Anyone have any basic measurements on a XJ? Roughly 35"s or so? 97+ drive shaft measurements...

I purchased the JB brand SYE and need to source a DS now

If they are the same as stock they are .312-24x1.170. That's 8mm-24 threads per inch x 30mm.

Where can I get those bolts? I tried buying M8x1.00x30mm, but they don't thread in properly.

EDIT: I think I found them here: http://www.performance offroad center.com/oscommerce/product_info.php?cPath=37_185&products_id=3767 (remove spaces) but its like $13 to ship them

I'd like to find them somewhere else.

EDIT #2: I found the Mopar part #, it's: 6034 966. A dealership should be able to get that, I'll try calling tomorrow.

Ok...this is quite possibly a NOOB question, but I am curious on something.

I have pulled my rear driveshaft off several times to lube it in an effort to correct the "thud" I would here after a stop.

Now then, this is totally hypothetical and just a curiosity question. Could I drill a hole in my skip yoke at stock length and one through the U-Joint flange and basically eliminate the "slip" portion of things. Then attach a front DS to this setup? I'm sure there is a reason for not doing it this way, but I recently pulled a DS off the front of a GC and was noticing how it bolts up...which got me thinking...

I mean is it really necessary to buy an SYE HnT?

This is my take on your question. I think the problem with it is the distance that the joint is from the transfer case. A CV joint ("double cardan") is much heavier than the single cardan joint of your stock driveshaft. Having that weight out that far is a lot of leverage which would amplify any vibrations if not make them much worse. In some cases, the stock output shaft has bent from people not having SYEs. I think in this case due to the weight and leverage it is at more of a risk of bending. You will notice that one thing the hack-n-tap does is shorten the output shaft. A shorter piece of metal is less likely to bend than a longer one.

Ok, the weight makes sense. I know that the front DS is meaty. I've never heard of the DS bending though. Being centrifugal I wouldn't think it could...but maybe during some rock crawling with too much pressure? Honestly, I wasn't planning on trying this I was just curious why it isn't an option.

just so you know there is no such thing as a 2001 FSJ Cherokee. It should be 2001 XJ Cherokee. Welcome!

I'm in the prosess of installing my hack-n-tap SYE from RE, but can't seem to get it to drill deep enough into the output shaft, without burning up the edges of the drill bit tip. I drilled a pilot hole as per instruction, but not sure if it was a 3/16 bit or not(I do know it was a little smaller than 1/4").

I'm not sure if I should A) go get a cobalt bit(not sure the quallity of the supplied bit), B) try a larger drill/tap/bolt, or C) remove the tailshaft and hit it with a drill press(but I don't know how easy/hard it is to do). Any one have any suggestions?

If you were drilling good and then just hit a spot where it won't drill any more, you've completely dulled the drill bit. Get another bit the same diameter, hit the hole w/ some wd-40 or other lubricant, and drill away, should solve the problem. Ran into this when I was drilling out my broken spindle bolts. Got so far and then the drill just stopped going in....switched drill bits and worked great. Going to invest in a good drill sharpener next spring.

Well I've been making a lot of use of my dads Drill Doctor and a can of PB so far, maybe today will go better after some sleep, I gave up last night about 8:30, too tired to think about it and was getting cranky.
I didn't think about the hard spot in the shaft(like I said, I was tired), gives me some hope though, just try to push though.
