Quick update.
Beating it over an anvil worked a treat. Hit, hit, hit, still seized

, then suddenly, it turns easy


. Much appreciated tip, and one I'll remember for a long time to come.
So, within 20 minutes this morning the track rod was back in place with two new ends. One of which doesn't want to let the nut do up (just turns in the socket) but I figure I'll leave that for a bit until the wheels are straight and try again.
The drop arm ball joint is another matter. I've spent hours today (until the better half called time) trying to get that fecking thing done.
I rigged up my own version of the tool that flat put me onto. A bolt, a 16mm socket a round piece of 5mm mild steel plate with an 8mm hole in the middle and a couple of different sized nuts. Pushed the upper doobrey thingy out no problem, (got my socket stuck for a minute but managed to bash that back out).
I then used the a small grinding stone in my drill to hone out the drop arm casting, which was pitted and lumpy inside. I've then spent the rest of the day trying to squash the inner parts of the kit and get the circlip back in. Fecking nightmare.
I just can't get it to squash in far enough. I've bent up a three way G clamp, then fecked around with a normal G clamp, got drenched twice in the rain and tried using a bottle jack to push it in place. It just lifts the landy up and still not enough of a gap for the circlip.
Missed my opportunity for a weekend MOT retest, and well and truly fecked off with it.
