I'll have to think about the possible correlation between braking, tyre wear and the steering box for a minute but generally a steering box fault will upset both sides.

Clive, braking is more than likely a sticking caliper on the left hand side. tyre wear will be tracking is out. Steering problems are usually during all driving conditions.

I'm yet to work out how your MOT test came up with play in the steering box causing the brakes to pull to one side.

Hi Clive, hope you're okay.

It may be worth checking the upper ball-joint on the offending side if the tyre wear is right on the shoulder (See pic). You'll need to check this with a bar as there's a lot of weight/pressure on that joint. A visual check at the back of the joint is advisable too.

If there is more widespread wear across the edge then your tracking or track rod ball joints or swing arm bushes may be worth investigating.

I believe you are able to adjust the steering box itself to tighten or loosen the steering, but this will be an unlikely cause of the uneven wear.

You can adjust steering boxes but it can be a bit involved to do correctly. Adjusting the steering box only adjust's the play in the box and travel on the steering wheelnot on any of the lower steering joints, these can be done indidually on each steering link arm.

I have to agree with Andyp, I can't see how the steering box can cause the  problem you mention. If the steering box wears the normal symptom is excessive play causing you to have to keep moving the wheel left/right to travel in a straight line.
The steering box is power assisted and I remember reading somewhere that sometimes fluid pressure in the box can become unbalanced and cause the steering to be biased more one way than the other. I would think you could prove that by jacking the front of the van up so both front wheels are off the ground, run the engine and see if the steering centers ok or tends to drift to one side. You don't want to adjust the steering box unless really necessary as that can unbalance it.
The MOT test should have shown up any wear problems with the ball joints, brakes and possibly idler arms but tracking isn't part of the test so you could get that properly checked.

Nobody's mentioned it, but as an honourary 'old bugger', I will....

A worn steering box would behave in a similar fashion to worn kingpin bushes in the old days. You would have to juggle the steering wheel to keep the car going straight. It wouldn't affect just one side.

Also worth remembering the difference between driving on the right & the left. Front suspension & steering alignment is set up so that the van naturally steers to the left (a bit) when driving on a road cambered to the right. (as in the USA)
Our roads are cambered to the left (of course) so the steering is always slightly out of line, so it should be worth a thorough alignment check, caster, camber & toe-in/out.
The natural inclination of the van is to drift to the left, so in the UK you're always trying to counteract the (slight) pull to the left.
Worth a check, any good alignment technician should be able to sort it out.
George
