castellated nut

has anyone out there used a paper or leather washer behind their castellated nuts at the end of the CVs. I have had a sh#t of a time getting one of them undone and was thinking that to avoid this problem a paper washer might make it easier next time. I have always used a paper washer on the chuck of the lathe as it is subject to the same type of shock loading , and it means you can always get the chuck off, without damaging the lathe or the chuck.

The 36mm nut is easy to undo...attach socket on long breaker bar, put car in reverse and slowly let out clutch.

Not quite so easy at a wreckers or on a not-running vehicle. Big breaker bar and plenty of force...

36mm socket 3/4 drive breaker bar, not an issue, torque spec for the nut is 196Nm, 144 ftlb.
No point in putting anything soft under the nut.

Like they all have said they are always tight make sure they are lubed when you replace them etc. Use a longer lever. I have peice of 50mm stainless tube that i use over my 3/4 inch socket handle as a longer lever to (crack)the nut before i jack it of the ground (bigger socket Drive= bigger Jumps on lever(without Breakage)). Always needs to be tight as they make funny grinding noise if loose

I wouldnt do that kind of thing because it'll wear down and cause free play then one day you'll hear funny noises and will drive you crazy. I do recall seeing washers and no washers behind the nut, always used breaker bar while the car is on the ground before I do further work on the car.

ok i get the message use more leverage, I just found that there was one really tight nut and it got me thinking about what I do on the lathe to prevent really tight chucks.
