Great work and I will be doing similar to mine but have one question how much steering lock is lost (or rather unusable) on high grip serfaces with locked front hubs so as not to destroy the cv joints?

None at all. You have a diff in the front axle.
The issue of transmission wind up which stops good steering when in 4wd on a hard and grippy surface comes from there not being a centre diff.
As you are not in 4wd the front prop is not engaged in the transfer box so if free. Thus no wind up is created.

Its also similar to a "field bodge" you can do when they fail off-road. Undo the hub with a Torx, pull the centre out into the locked position, drop a small nut from your parts box through the centre of the hub and jam it in behind the slider (this prevents it unlocking accidently).
Its a real bodge but I have used it to stop the hub failure ruining an off-roading day.

2003 M13 early KAP build.
3" Trailmaster lift with 1.5 Spacers on front
Customised winch bumper and roll cage
235/85R16 Maxxis Bighorns on 16" Rims, 4:1 Rocklobster, Rear ARB locker and on-board air
Corrected arms all-round, rear disks, Recaro seats and harnesses
Twice it has happened to me that my hubs have not disengaged after a period in 4wd and on both occasions the car behaved as if the front brakes were stuck on if full lock was attempted I thought this was due to the cv's as once I have got them disengaged by putting it in and out of 4wd a few times I could use full lock again

Advice given by PM and thread tidied back to original topic.

I have some spare vac hubs and my locking hubs need a service as they no longer work. So I am going to attempt this today/tomorrow and test it out during the week.
