which tools?
 

what size nut driver do I need for the ballcups on a b4? obviously it will need to go over the ball inorder to get to the nut aswell.

also which hex for the pinion grub screw?

Thanks

Pinion grub screw is 1/16". Bit confused about the other one, do you mean ballstud? If so it is 3/16"

sorry I mean ball end.

pinions can be 0.050 or 1/16th if imperial, if metric generally 1.5mm

never seen a driver for the ball end

yeah..the things that turnbuckles fasten too.

Yes you mean the ball stud, and yes it's 3/16"

ballstuds 3/16", pinnion 1.5mm (unless you have crazy American pinions which are 0.050" usually).

If you are replacing tools, in my opinion, Hudy is unrivaled in quality,and RW are excellent for the money.;)
