Still sounds like CV to be honest. Were they new axles fitted?

worn rack bushing make knock sound so do faulti stabilisator bar bushes and rubbers when the force in the bar knocks on metal instaed of getting dampened. Fastest way to find that is to rock the car back and forward on the roof

Maybe the steering is turning too far in one direction. You say it locks up, which means the car doesn't want to move forwards ? It sounds like it's in the cv, and if they are good ones, it could be caused by the steering angle being too great for the cv to handle. Did it do this before the new cv's ? And so that's why the new cv's were fitted ?

What locks up? Just 1 wheel?

You say it can be "turned back forcibly". So do you mean that the steering wheel locks in the turned position and it requires great effort to straighten it up again?
If so there is something binding up in the rack, tie rod end or similar IMHO.

yes did it before cvs where fitted, thats why they were replaced, yes steering wheel locks in turned position requires great effort to straighten it up again. am just relaying what shes told me am yet to have a look myself, apreceate the feed back as its giving me a good idea where to start

If the steering goes around to too sharper lock, the angle between the steering rod and steering arm can go over center, and then the wheel gets jammed onto hard lock. I've seen it on quad bikes that had lots of wear. in a car I'd suspect that whatever is meant to prevent the steering going to too sharper angle, is missing or damaged. The noise is probably the cv, but only making the noise because the lock is too sharp. Check if the lock angle is the same left and right turns.

I'm guessing it's an auto. almost guarantee it's torque bind from the gearbox/centre diff.

you mean 4wd uneaven tyre wear low pressure would stress the system one of the worst is toyotas . One of the best is haldex used by vw

Is this just another dig at Toyota or can you explain which Toyota systems you consider to be "one of the worst" and why.
Do you mean the part-time system as used for example on the 70 series, or full-time 4WD with a locking centre diff, or full-time 4WD with a viscous coupling and locking centre diff, or full-time 4WD system with a 'Torsen' T3 (torque sensing) centre diff?
You say how wonderful the Haldex system is. Early Haldex systems were pretty horrible until Generation 3 as used on 2006 on Freelander.

My legacy had that locking ,binding noise on full lock ,I fixed the problem by putting a tube of tranny fix in the auto it fixed the problem straight away.You buy it from any BNT shop ,also you can put the car into 2wd by fitting a fuse into the empty fuse holder under the bonnet by the brake booster ,the fuse holder has AWD written on the cover put the fuse in and see if the problem goes away .
