Access to the steering box for adjustment (gen 3)

Yep, I think you want a jumbo 300mm+ slotted screwdriver. If you have an open end ring ratchet that would maybe help you turn the locking nuts whilst holding the screw in place (e.g. www.amazon.co.uk/Flexible-Spanner-SUPERT...atchet/dp/B07R1VPL17 ) but might be too tight for it and it has to be long enough.

I couldn't actually figure out what what size the locking nut was though! Something like 16mm but nothing felt like it would sit nicely and then it started raining so I went inside Anyone know the size for sure?

Pic for reference (pls ignore my yucky headlight rust, it's what I do).

Yes it is an awkward method and makes it tricky to do precise adjustments, but it's better than the alternative of disassembling half the front end to get proper access.

Woohoo, managed to get in and do the job! Super pleased with the results so far, she feels way less floaty / sloppy. My steering damper actually feels like it's doing work now. It obviously always was but before this slop / wear meant it went from super light steering to heavier, that has 80% gone now. I did a 1/8 turn on the screw, nothing super aggressive because I am wary that you can damage the box and you do want to leave some give.

As for the job itself. The locking nut was really tight, even after some WD40 a few days ago but got it off with some oomph. Think it was a 17mm socket on the locking nut and then a universal joint + extension. I also partially unscrewed the lower 10mm bolt that slightly obstructs, not sure if it was totally necessary. Used a massive screwdriver - 9.5x450mm to turn it (could probs use a shorter one but saw this on Amazon so why not). You can kinda worm your left hand in at the bottom to feel what you're doing whilst tightening which is helpful. I must have looked very graceful with a LIDL torch in my mouth and a massive screwdriver in hand.

Very happy now. I will be interested to see how this makes handling in higher winds because before it was a real bum clencher (the slop obscured minor adjustments you want to make as you get blown about). Honestly the car feels like a new vehicle from when I got it. New tyres / brakes / wheel alignment / box tightening + a steering damper

Oh, and a wee photo of course.

 

I need to do this.  My significant other is complaining about the steering being a bit baggy (I've explained they're all like that to some extent, even when new).

What's your year and mileage? For reference mine is ~70k / 2007 and I had a really obvious improvement out of that 1/8 turn, definitely not placebo. I've never driven a new one though and wear can creep into the steering from so many different places so it could be something else in your case.

But the box adjustment has been great, was just driving earlier today again. I think the way it is interplaying with my steering damper is very nice because I am barely getting wobble over bad surfaces now. What I am yet to test is going up to motorway speeds but I think it will be good.

And for someone who isn't a noob like me it'd probably only take 10-15 mins to do. I recommend taking a picture before / after so you can be sure you haven't over tightened and can see the locking nut is back in position.
