Changing a CV boot

[33grinder]

I need to change a CV boot on the blue 66 saloon and it is the vario end of the driveshaft. The bolts are cracked off fine and won't present a problem, thankfully.

The club supplied a new boot in double quick time which is great, but I've not fitted one before. The boot appears to be sturdy rubber (not the cheap plasticy type) and is integral so not the fit it and glue the joint down the middle type.

All I can think of is boiling the kettle (well, that goes without saying! ;D), immersing the boot in hot water to make it more pliable, before turning it inside out and pulling it over the cv joint in the hope that the narrow end will stretch enough without tearing.

Is this the right way to go about it? I don't have one of those cone things neither. I know the metal clamps are best binned and replaced with jubbly clips though.

I looked on YouTube to see if there were any educational videos and whilst I didn't see any, strangely enough I did encounter this one which, whilst...erm 'titillating' leaves me none the wiser. Any ideas?

Pete is it inner or outer CV Joint?

Outer

Undo the hub nut so that the drive shaft can be pulled out of the centre of the hub, most vehicles require you to undo some suspension mountings to get enough movement. then Use a soft faced mallet and tap the CV joint off the end of the drive shaft should be splined to it. Then slip the new CV boot over the drive shaft small end first and push the CV joint back on, again you may need the mallet to get it home. Push the CV boots large end over the CV joint that you've packed with the supplied grease and jubilee clip up. No need to overlly stretch or to turn inside out

For inners just remove the driveshaft from the vario and tap the CV joint of its end. Repeat as above.

Cool, thanks Paul. I wasn't aware of how the CV attaches to the shaft. I have visions of lots of ball bearings falling out and rolling all over the place.

Bolts are cracked off both ends but will see whether I can remove the cv with the shaft in situ. The split gaiter is at the vario end, btw.

It's not quite that simple, at least on the inners, for these. Rather than using a snap-ring to hold the shaft in the joint (the usual way), Daf decided to put a circlip on the drive-shaft at the inboard end of the inner joints. To make up for that, they were nice enough to have both joints simply bolt into place so you don't need to remove suspension stuff to take the driveshafts off

So, following Page 8-4 below:

undo the bolts holding both joints (inner and outer) and lift the driveshaft out.
Remove the circlip from the inner end of the shaft
THEN tap the joint off the shaft. They say to press it out, but sensible tapping should do the job instead.

Just in case the joint decides to come apart while you're doing this, page 8-5 below shows how to put it back together

Fair does Joe ive only ever changed them on moderns. Seems like a fairly easy job in comparisom to doing them on a VW Polo

[spunkymonkey]

Yeah, it's a pain having that circlip in there rather than a snap ring if you're not looking for it but the bolt-on / bolt-off idea looks like a nice bit of design!

Not quite my idea of a fun afternoon either
But, you have to do what you have to do Pete. But it's not an annual task. ;D Mine were done in 2006.








Be sure to take a "patience pill" before beginning.

I know those metal clamps are perfectly fine if fastened correctly

That's so you can remove the nearside one regularly, just to see if the stub axle nut has loosened itself...

[spunkymonkey]

They didn't use a r/h thread??

[macplaxton]

No they didn't!!!!!

When I took the n/s driveshaft off the 66, I found the nut sitting there....loose

It's a half-height nut or something, with no mechanical locking. Just a high torque (4.5 grunts on the big pole ;D) and a dod of Loctite.
