CV boot makeshift repair
I know I know that I am going to get slaughtered for this post
but work with me on this one...
I have aging parents that I must go see in LA this weekend
Friday AM driving from the Bay Area ( 850 miles round trip)
I have a bad CV boot outside right rear. I ordered a new one and it won't arrive until Saturday. If I pack the current one with grease is there a way I can keep the grease in it until I return on Monday. It's not ripped, but separated from the hub side.
It just so happens that the 928 is the only car in my motor pool that is worthy the trip other than my Sunbeam Alpine and I do need to get there.

Well.....In the for what it's worth category...wrap it in saran wrap or something a bit stronger, SEVERAL winds around, then duct tape it, tie-wrap the ends and each pleat and hope for the best. Note that the joint is at the outer end of the boot, so there is no need to pack the boot. I'd just wrap it and hope it does some good. If it's just a single split pleat, many people drive around for years like that and only throw a little grease.

I just heard that there are split boots sold for quickie fixes. If I can't find one maybe
follow Bill's suggestion. I do have few bags of concrete around maybe I can mix up a batch :-)

Has it jsut slipped off the hub or has it cracked around its circumference adjacent to the hub?
If it has slipped off just remove the clamp and slip it back on and reclamp.
If it has cracked around the circumference, purchase some rubber welding tape (self amalgamating tape), clean up the external of the boot with a solvent , get the half shaft in axial alignment as best as possible and then stretch the rubber welding tape and tightly wrap it around the crack extending it longitudionally to give the tape a good grip on the existing rubber boot. The rubber tape will form a self welded rubber seal and you are on your way.

Fast tempory repair , Dunno what it's called in the States , Shrink wrap, kitchen cling wrap, get a roll, wrap it around about 20 times, run some duct tape around for insurance, will still be there when you get back from your run.

Some time ago I set about sorting out the CV boots, one of which appeared to be split. However upon removing the half shafts I found that in fact it was simply leaking from the larger end, which wasn't sealing properly because of damage to the CV joint casing (and the use of cable ties). I swapped the axles to increase CV joint life, but didn't have anyway to improve the CV boot seal.
Last month in preparation for the MOT I bought a Laser 2916 and some steel bands.
http://www.toolbox.co.uk/laser-2916-...t-14273-112666
There was enough room to fit bands to both the inner and outer CV boot in situ, the tool made it such an easy job, I wish I'd bought one years ago, it wasn't even that expensive - I expect Harbor Freight do something similar for under $20.

What a great tool!
There is a Harbor Freight in the UK? The Chinese are loving it.
Thanks all for the tips.
Going to crawl under and make it happen.

Big question!
Today, I received a new CV boot kit from Mark Anderson. A day earlier than expected.
Hurry up and wrench away, easy job everyone says. I made the mistake of only taking off one end (outboard) Pulled the nut off of the axle, but when taking the boot off the
bearings fell out. No big deal... cleaned them off and realized that to get the new boot on I still have to disconnect the half shaft from the transaxle. Ok...everything out. Cleaned and put it all back together and now to re install. (what a greasy mess)
New boot is on and looking good on my bench. Put the transaxle side on first, struggle with the spline, but now it is does not seem to fit. What seems odd to me is that since I have reassembled the bearing race nothing is as flexible as it was prior to
taking it all apart? This easy job has taken a life of it's own. The outboard end
does not want to fit flush to the axle. Where did I go wrong? Do I need to take the race apart again? My rush trip to LA is now in my daughters TDI.

I assume that you can't get the splined end to go fully home in the hub? If that's the case carefully take it back out and clean the splines and the hub bore, then before you put it back together again smear some anti seize on both surfaces. If there's no damage to either it should engage fully.
If you're feeling that the CV is not as free, it could be that you don't have it assembled in exactly the same way. The components tend to wear to fit, if you know what I mean, and mixing all the components up so that wear surfaces aren't matched will cause some loss in smoothness .. and perhaps some premature wear in future as the surfaces wear in again.

if it is not flexible enough check inner to outer carrier alignment. Inner wide part next to outer thin part. The pics (halfway down) on Sharkskin's pages show it

There is also Dwayne's documentation but can't get the link at the moment.

Ah ha!
I see exactly what I did wrong. Thank you very much...
Do you think it's a good idea to do all of them since I am into anyway? It appears to me that it's not a bad idea to do the entire half shaft even though the inboard boot looks Ok. Both sides as well?

I would - I did.
I had a split outer boot - so on the later driveshafts both boots need doing anyway then. Then last night while staring at the underside of my car, I decided to do the other side as well. Might as well use up all the cleaning stuff and get the mess out of the way.
My bigger problem is that I have the tank out also and am having a bad attack of the 'while you are in there'. Keep taking stuff and and do TT bearings, Superclamp, trans and PSD hoses....or put tank and drive shafts back and enjoy the summer and go back in over the winter. One of life's better dilemmas. :-)
