Clanging sound, goes when clutch down. Anything other than CV stuff?

Happy new year - New year, new knocking sound  :D I have an irregular knocking / clanging sound that came on quite suddenly a couple days ago. Increases with speed but is not uniform. Goes away when clutch is down. I'm guessing it's a CV problem. Just wondered if there is anything else that it could be that should be checked?.

If it came on suddenly I'd probably check that your driveshaft bolts are all tight before driving the van anywhere. If a shaft drops out it will often damage the gearbox (and will leave you stranded)

ah yeah thanks, gearbox was refurbed a few years ago. Can I just see if it wobbles by hand? (There's movement back and forth /in and out which I'm assuming is expected). Or should i actually check the bolts are tight? I'm Just reading the wiki now. I'm looking forward to laying on the floor in the snow...

Check wheel bolts too, have you got factory wheels and hubcaps ?

good point regards the hub caps!

If there's noises then you'll probably feel loose shaft bolts by hand, but it's worth going round with a ratchet to be safe.
It's worth checking them from time to time anyway, they often come loose especially after they have been disturbed.

I've got Mefro steels on. I'll check all bolts and wheel nuts. I did a cursory check of wheels and a quick look at the drivers side cv and shaft. I'm nervous of rounding them off so will probably clean it all up under there first. Gearbox was off about 3 years ago so bolts have been moved 'fairly' recently.
