Why do you want to remove it?
I understand it is loose but simply cleaning, adding some sealant, re-tightening should do the trick.
The back of the 'Wheel box' has a mounting plate which clamps to the tubes the drive cable runs in so to remove the wheel box pretty much the whole wiper mechanism has to come out.
If you still want to take it out I can explain the sequence and some tips for re-assembly.

It sounds like you've got a different wiper mechanism from me Steve. It's not a cable and box type, there are metal rods that link across to the motor on the left and the offside wiper on the right. The rods connect to a triangular plate, the third point of which is on the shaft that connects to the wiper arm. This shaft passes through the body in a tube/bush, and it is that tube that is loose.
The problem is that there's a fair bit of lateral force applied each way in turn as the wiper goes back and forth, and the tube rocks slightly side to side. This alters the wiper's rotation axis as well as being a potential water entry point. Adding sealant could fix the latter point but the tube would still rock.
But there's no play in the direction in/out of the body, and I can't see how the tube is mounted to the body.

If you have the early type there's a nice picture of all the bits if you scroll down this old thread and look for glenrobbo's post.

Thanks Mick, I hadnt seen that.
Yes, that is the earlier type S1 wiper system with crank arms, rather than the later cable type. There is some overlap but it appears the crank type had gone by August/Sept 1988.
Be **** careful not to put your hand under the dash when it is working, it will cut your fingers off!
The original appears to be obsolete ACDelco used on Vauxhall/Opel and at least one Peugeot.
The problem is caused because the system has a slight angle on the S whereas it was designed to be straight, that puts a rocking load on the left hand pivot, I take it is that one which has started to move? If it is left it gradually damaged the grp and the spindle.
I am sorry but this may not be an easy fix.
With the arm off there should be a thin brass nut holding the spindle into the sleeve, that should release the spindle to pull out from below, but not easy to do. Once the spindle is out it is then a question of securing the sleeve. Two choices, re-engineer it completely so it can be secured mechanically, which would need a machine shop. Alternatively you will have to clean very carefully above and below and remove any damaged gelcoat or grp then use a generous amount of a very good quality epoxy to 'glue' it back into place. Grease the spindle well when you put it back and make sure the ball and socket pivots on the arms are free and greased. Also make sure the motor mountings have not come loose as well.

Phillpot - thanks I'd not seen that thread before so I've saved a few chunks of text as well as the photo.
Greymrj - thank you too for the info. I can do fibreglass work but was hoping it was something easier. Yes it is the left side post that's loose. I've already removed the motor and link rods. The motor was firmly mounted but its bracket was rusty which is why I removed it.
