It's described in many threads - and yes I have done it without taking the wheel off at the side of the road just before the start of a Rally - when told there will be rough roads ahead. In that case - I was raising the suspension. Low is fine for the track - high is good for rough roads!

Few hand tools and a hammer - easiest with two jacks but can be done with one jack and a brick........
basically you have to separate the front suspension lower arm - only the rear part is splined on the T bar. Of course it's under load - so you have to hold it on a jack (or a brick....) and either lower the jack - or raise the car until the load is released - then knock it back on the splines, move it one spline up to lower, or down to raise - hammer it back up the splines - re-apply the load, and connect it back to the front half arm. 15 minutes a side once you know what you are doing. Obviously - first time may take slightly longer. Douse the splines with release oil for a day or two before you attempt the job.

Where will you support the car - on 2 point car lift?? Not a good idea - do it on the ground - where you can unload the T bar safely.

from looking at that diagram i raise the car , then support the hub, remove the bolt at the front of the torsion bar, lower the support on the hub and the torsion bar should pop out then i rotate the torsion bar by 1 spline reposition then redo up bolt and loower car down?

Err -not quite!! The T bar doesn't pop out of anything!! You need to undo the fixings holding the rear arm to the front arm. The front arm remains attached to the king pin (so brakes/wheel can stay on) and the eye bolt . Put the jack under the rear arm, and jack the car upwards, easing the lower trunnion away from the rear arm as you do so. Then you lower the jack till the load has gone, then just slide (more like hammer!) the rear bar backwards on the splines till it comes free - move it up or down - slide (hammer) it back along the splines, jack it up again, fit the trunnion back on and do up the fixings again. Simples!

The Moss diagram is by far the best - shows all the parts in relative positions. If not sure - don't attempt it - there's a LOT of energy stored in the T bar.

ive done torsion bars before on the back of a mates renault clio this was to lower it but that was quite simple.
would i undo any of the bolts on this picture of the torsion bar (not my car btw)

No! None of the bolts you need are shown there. Lowering the Minor couldn't be any simpler! You need to remove bolt 90, nut 112 and nut 96. That's all.

I'm with you Roy - if you're not sure LEAVE IT ALONE!! At least read up on it thoroughly with the manual and the car in front of you. The load on the bar is very strong and can cause some damage if you aren't careful

X3 If you haven't worked on the suspension before this is not the smartest place to start!

I also agree, unless you know what you are doing, and if you did then you would not be asking, do the job properly with the car supported on axle stands. You can do a lot of damage to the car and yourself if the suspension slips under load. By the time you have read these posts you could have removed the wheels anyway.

I think the wheels are the least of the worries here.......

With all due respect, are you really sure that you understand what effect it will have on the handling of the car, both in normal use and in extreme circumstances, such as heavy braking while cornering? There are contributors to this board who have the knowledge and the experience to feel confident that they could stand in front of a judge, or the coroner, (or the Procurator Fiscal) to explain why they knew better than the people who designed the car, and there are some who just hope they'll never need to. They're probably right, it's very unlikely...
Roy and the others are dead right about springs. They go with a hell of a bang if you get it wrong.
