Look in service bulletins there was one that called up loctite to stop hub spline movement. Look at Bulletin # 0001. CDSRef L8431bu. Issue 2 Date 26/04/2000. Putting an endoscope to your ear is a good one.
Well I'll be a monkey's uncle. That's the symptoms all right. You think the Loctite in mine has just had it through age and allowed some play? A smear of Loctite doesn't seem too robust a solution for a drive-train. Interesting that it says torque the hub-nut up to 340 nm whereas RAVE says only (!) 260 nm. I don't even have a wrench that goes up that far.
Well, none of my local motor factors had Loctite 648 so I checked the Henkel website. None listed there. So, rang their technical support line in Hemel Hempstead (just up the road!). Very friendly and helpful guy in their technical support (industrial). Apparently 648 is not automotive, it is industrial and Range Rover buy it off them in barrels! They also have Loctite 660 for where parts are a bit worn but I'm sticking with the 648. He found me a local supplier PDQ. I mentioned I'd seen some on Amazon and eBay and his instantaneous reply was "I wouldn't risk it on my car. I've no idea where they're getting that stuff." As many of the bottles had chinese writing on I have to agree. Given the importance I'm not risking a £200 hub for an extra tenner. Should be in the post this afternoon.
Will see in the morning if it is cured.
In the meantime I need replacement brake shield bolts (the little 8mm ones), a brake disk screw and probably the brake caliper bolts. The bolts holding the hub assembly weren't too pristine either! Considering replacing the rear disks. I had to hammer the damn thing off and I caught it a ding at some stage and left a slight mark.

Fixed!
Once again no noises and silky smooth. Another one for Wammers!
Looks like the brake shield bolts are M6 x 12mm with a 8mm 6-point head? Screw for brake disc is M8 x 20mm, countersunk? Caliper carrier bolt is M12 x 35mm with 15mm a 12-point head. Or was it 14mm?! My memory is shot already. Might have been 14mm head, now I think about it. beginning to think I might have to replace the 6 hub assembly bolts too. They had a 13mm 6-point head. Not sure what size they were, M8?

Yes, brake shield bolts are M6x12mm - the ones I got a load of were stainless - but had a 10mm head on them - they fit and work though.
I'm not sure about the others as I've been working on the front the last couple of days and I think everything is a bit bigger up there...
So just out of interest... did the loctite stop the excess slop in the hub rotation? or just the clunks? All 4 of my hubs have some play in them, and I have been considering loctiting them... I wonder how much more work it will be to pull the driveshaft out after it's set?

No clicking or clonking at all. According to that bulletin the rears of all cars should have Loctite 648 to stop any play. Doesn't go on the front. If you check the Henkel (Loctite) website it'll have the technical data sheets. I think if you heat the 648 up to 150 C it'll break down so just a bit of heat required to pull them apart again. It says to pull apart in the vice but mine just pulled out with my fingers. No effort at all. Driveshaft off a scrapper is £30 delivered so not going to break the bank if you're already paying £200 for a new hub. After all, why else would you split them unless the hub or bearing was FUBAR'ed?
If you have lots of wear then some of that Loctite 660 looks like it'll do the job. £30 a pop but cheaper than 2 x £200 hubs from http://www.shop4autoparts.net/.
