Yeah the replacement should be the exact same length as the original one...so when you pull the shaft compare them at that point. IIRC there is about a 1" difference between the two. I believe QD shafts are slightly shorter.

done this plenty of times! never on my jeep though, (mostly wranglers, few pickup trucks) but glad to know if i need to it's real easy. question though, i know on wranglers and some other jeeps the pad snaps into the caliper which makes things real easy when you slip it over the rotor. Is it the same for the WJ? Recently did a brake job on a mazda b2200 and it was a pain in the ***. thanks in advance arlo!

Another question. What kind of poundage would an impact wrench need to get that axle nut off?

The 3 hub bolts are the biggest PITA I've ever dealt with. I had to heat them up with a torch to melt the large amount of thread locker the factory used then they came out.

Theoretically, it's held on with 175lb/ft of torque. But that number can grow immensely depending on rust and scale. I used my impact gun on my '99 and it zipped right off. I think I did let some PB Blaster soak in there for a few minutes beforehand-

I heated the nut almost red hot with an oxy-acetylene torch and a small tip so the heat stayed mostly on the nut.
Let it cool some and PB Blasted it. Then it came right off.

I then cleaned up the shafts, ended up scraping scrubbing them clean and baked them in an oven at 500 degrees.
I then JB welded the shaft to keep down the rust and replaced the u joint.
I greased it all well when putting it back together.

If you want jb weld to speed up the cure to an hour or less, simply heat the part you put it on to around 120 to 140 degrees.

The impact wrench I got can do 240 lbs I think and I got a can of pb blaster as well. I'm probably going to be tackling this in the next week or two. I want to do it but keep procrastinating because I'm afraid of something going wrong . I just need to man up and get 'er done.

Its super simple. It was the first thing I have ever done to my jeep. I was shocked how easy it was. Just soak the bolts on PB Blast or some liquid wrench and they should come right off.

well i just finished the right cv shaft.. those 3 bolts were a PITA, and the hub was seized up real good too.. used A LOT of PB Blaster.

Im not sure if anyone wrote about doing this (i didnt read 10 pages of replies), but to remove those 3 bolts without a torch, i proped the base of the handle of my wrench on the jack and pumped until it was fully extended.. then i readjusted the wrench and repeated.

Just a tip for those that do this - use anti-seize on all bolts as well as the lip of the unit bearing. Makes the next time a whole lot easier.
