Hi Guys,
Whats the easiest way people remove the nut on the end of the cv?
Are the clock wise or anti-clock wise to Undo?
Any Tips/Tricks Would be great.

Rattle gun. Can't remember the thread directions.

I use a large breaker bar with a pole off a trolley jack slipped over it for leverage. Get a friend on the brakes and put your back into it. thread direction is normal, Left = Loose, Right = Tight.

32 mm socket, normal thread. Jack the wheel off the ground, remove wheel. Remove split pin, put screwdriver in slots of rotor so it rests against the caliper and use a breaker bar on the socket. Sometimes the nuts are tight, but the manual says 200 - 260 Nm, which is only twice as tight as wheel nuts. Some people - eg previous owner - do them up real tight, which isn't good. Wheel bearings take their preload from this nut, overtighten it and the wheel bearings can suffer. (HINT: most cheap torque wrenches go up to 200 Nm, buy and use one. lol)

Umm, arn't you meant to put a 5 foot bar on it and stand on it when you tighten it, that is what I was told by someone and then when I asked about the torque I was then told that I do not know as much as this person, hmmmmm
Seriously, as above, this is exactly what I do, generally I will use the rattle gun to remove but I always use a torque wrench to tighten them
Oh and a pet hate, they are BRAKES not BREAKS lol

Yep, Madmagna gave me the method of jamming a screwdriver in the rotor, used this method recently and it works a treat. lol Manual says to have no load on the wheel bearing when you undo the nut, so the wheel has to be off the ground anyway. No need to stand on the BRAKE pedal at the same time. lol
I bought a second hand set of drive shafts off a TP years ago, wrecker who pulled them off the wreck said he had to use a breaker bar 3m long to shift the nuts, and one of the threads was stripped. Slightly over torqued, me thinks! lol
EDIT: Use a 1m breaker bar, if you must. lol
If you weigh 100 kg. and stand on the end when you do that nut up you are applying 1,000 Nm of torque. Just a little overkill there. lol
Standing on the end of a 30 cm long 32 mm ring spanner gets it there if you don't have a torque wrench, as long as you weight about 85 Kg. lol
85 Kg X 10 X .3m = 255 Nm lol (But the spanner has to be horizontal.)
