outer cv boot replacement

Hi I have read all the post i could find great input from all, but 2 questions, can this be done without removing the axle nut (collar nut)? and if i get to the point of freeing the shaft (A) out of the cv / bearing casing (I), can i just leave the cv casing and bearings in place, re grease them and then try to pop cv shaft back in? went and bought myself a new axle nut in case it does have to come off,

No, you have to disassemble the bearing between (A) bearing housing (I) to replace the CV boot.

thanks for the input , yes i know it has to be split so the boot can fit, but can i do this without removing (i)? and just repack (i) with grease and pop (a) back in? and not take off axle nut not shown here

When i did mine, i removed the axle completely away from the X and working on it. Yes i removed axle nut and replaced with new nut from dealer. I do not recommend you to replace the cv boot just "repack I with grease and pop A back in", it is not my way to treat her. Look at the picture you attached above, remove the axle nut and pull the axle completely out, hold (A) and using plastic heavy duty hammer band down the bearing case (I), install the new cv boot with grease and reassemble, you are done.

I would think that if you tried pulling the CV joint off the axle, you will end up pulling the inner joint out of the differential.

Yes, you should pull the entire front axle out of the differential to replace the outter boot and just leave the inner boot/bearing alone, work on the outter then put everything back.

thanks for all the input spent 2hours with my mechanic, and laptop with pics and got this done will go through in more detail soon, but basically
1.took axle collar nut off (bought new one to replace it)
2.brake caliper and roter removed, caliper hung os spring with zip tie and out of way
3.abs sensor disconnected too and out of way
4. and undid all other bolts or control arm and wishbone and whatever was in the way
5. used a 3 prong extractor tool with pnuematic gun to force the outer cv joint inwards towards engine and away from the hub which we didnt remove
6. this then left the axle hanging and we cut of the damaged boot and started to tap it on the flat section of the 'star' shaped part of the housing that holds the bearings, wouldn't move, then twisted around in different positions and with one tap it came loose, be patient don't give up my mechanic at one point was insisting it would not come off and that it was fused in place!
7.pass retaining clips and the new boot onto axle, cleaned and greased bearing and housing and then proceeded to re-assemble, and not much force needed to put cv joint back together, the c clip on the axle will make a clicking noise once it is seated, diy on home page gives more details
8. pass through the assembled cv joing with the new boot cover into the hub
9.line it up and whack it, and then proceed to loosely attach the rest of the bolts takne off earlier, at this point use a chunk of wood over the hub and pound it until you see the end of the cv joint protrude through, you need just enough so as to be able to screw on the collar but
10. the rest was history, so far so good, took it for a 10mile drive over mixed terrain, both pot holed, mud roads, and highway, checked it and still looks o.

will add more details as soon as i can, didnt take pics as it is all included in the diy and posts by other members.

I know this is a very old thread but just to close the loop on this subject, it certainly IS possible to change the CV boot by removing axle "A" from CV joint "I" without removing the CV from the knuckle.

It does take a knack and a helper (or a third arm) but with the rear control arm disconnected at the sub-frame end and the suitable application of a suitable force in a suitable location, the axle will pop out of the CV inner pretty easily. Slip off the old boot, slip on a new one, re-grease the joint, close up the boot etc...

ok fella good to know, right that mechanic that took 2 hours had never touched an X5 before, soon after one side went the other side went too, I saw another mechanic wip it all off in about 20mins then he went slow motion mode and I decided to leave garage.....wpoll ironic you should bring up this post as when car was on ramp last week during starter removal i noticed some surface cracks in the rubber of the circumference at the smaller end of the cv boot nearest to the the clamp holding it on.....shown with red line in pic.....so I got some bison rubber glue and coated whole circumference of affected area up to top of nearest first below below and also the actual clip holding boot.....ps i also sprayed in past with silicon spray as a preventative measure to prevent dry cracking.....

I personally think the best solution when a boot rips these days is just replace the cv axle.

Axles are $70something dollars at autozone with lifetime warranty. Just isn't worth the hassle to go any other way as cheap as they are now. Just my 2 cents.
