CV Joint replacement

Doing some brake work on our 99 Jeep Grand getting it ready to sell - found a CV joint boot torn PS - anyone replace one of these? How hard, how long, any special tools I need. May just take it somewhere but will do it myself if it's not too involved.

Do I need to pull the hub and axle or are you talking about a split boot and gluing?

I just replaced the boot on mine, and cleaned out the joints, umm yeah use the cheater bar, easiest way. And make sure you have a "banding tool". Not having that tool really screwed me over

Thanks guys, I bought the whole shaft and coupler (rebuilt) for $59 already assembled - It's about 3 feet long most it being the shaft going into the axel housing from the coupler, does that sound right? I was expecting a shorter shaft to mate with another shaft in the housing for some reason - this is a 99 with the Quadra Drive progressive coupler in the front.

Never mind, I read the link on installation - it looks like the shaft in that set of instructions so I guess its right. Only bummer is I have the calipers and rotors off alreay for the brake work so I have to reassemble probably to brake the axle nut loose - no biggy - looks like a simple job.

fortunately for me (in a wierd way) I just replaced the hub and bearing on my 3/4 GMC truck, and have all the tools to do the job already including torque wrench that goes over 175, 36mm socket, and a LOOOONNNNGGG Breaker bar. There were bolts on it I had to torque to 220 ftlbs.

does not have a progressive coupler. you have limited slip differentials with the quadra drive. you need to make sure they gave you quadra drive shafts they are shorter than the select-trac axles.

BE sure you have 12 point 13mm socket.

Quadra Drive has the gearator pump that engages more as the difference between the speed of the tires increases. That's not a limited slip is it? I thought that was a progressive coupler (jeep calls it a varilock differential)? My understanding is limited slip engages more as the the temperature of the gear oil increases - caused by friction of the clutches against the spider gears caused by speed difference? Am I wrong? Selectrac is completely open differentials with no clutches I thought. Quadra Drive II has an Elocker with clutches instead of the progressive coupler I thought, they do call it a limited slip I believe with an elocker ?

If I'm wrong, I got the wrong shaft. let me know what you think - is a progressive coupler not a varilock differential?

you're combining definitions.

progressive coupler= the clutch pack assembly in the transfer case

vari-lock= the clutch pack limited slip mechanism in the differential

This is where I read the terms - here they mention progressive diff with the term Varilok for the Quadra Drive system.

Admittedly I am likely confused.

you're seeing "Center Differential" That's the Hi range (all time) of the transfer case.

This doesn't even apply to the OT....


x2 on having teh 12pt 13mm socket. <--do NOT use a cheap socket, or you'll quickly round off those 12 point bolt heads.

I put PB Blaster on the 13mm bolts last night - broke one loose with a wrench and wrench cheater (adding a 9/16 wrench coupled to it) Have craftsman sockets so not the best - hopefully I can get them off ok - I think all my snap on metrics are 6 point sockets.

this is the line in section 4 at the top of the page I was looking at " Vari-Lok front and rear progressive axles"
