Can anyone point me in the direction of some guidance on replacing the steering shaft on an S2 please? I managed to remove the pinch bolts today, but getting the UJs off the splines proved impossible

. It seems that I need to create some slack in the system, but how?
Also, can anyone advise on removing the nuts to the caster mount eccentric bolts. Either mine have seized, or they are on bloody tight! I've soaked them in WD40 today, and will try them again once it's had a chance to penetrate, but any advice gratefully received

.
Phil
