No disrespect to anyone but when I asked for assistance I meant actual physical assistance ie someone being here.
I understand written help is useful but I can't do this. :( I've tried but I am really struggling.

Looks like its off (Facebook). Bottom ball joint goosed too!

Yeah , just spotted that myself. At least fitting a full arm and bush should be straight forward although those rear bolts can be a bit of a tinker. Been there and done that so only use quality parts if you don't want a repeat next year.

Excuse me. Where do I find this ??--( Facebook. 0

I find it hard sometimes to read these types of post as I've been in similar positions, and helped plenty of others in similar predicaments where possible. It does prove the wealth of observations and techniques on how folks do things and how sometimes these cars push us to the edge of our limits.
So the member removed the item in the end, but was no better off in the long run based on the fact of the joint being passed it, surely you don't save time leaving the arm in situ to replace the bush ?
A few more bits to undo, then its off and can have all kinds of techniques applied to remove even the worst of bushes - Just my observation and not looking for praise or recognition, just simply stating something obvious !
But here is the bottom line for jobs like this -

If it can be done without disturbing the lower ball joint and the lower strut clamp ( both of which can be a mare to remove and assuming that they were serviceable ),then I would just remove the bush but it is personal choice. In this case, the ball joint needed replacing, so the arm had to come off in the end.:shrug:

I have been luck with help but if there is no one in your area to help surely written help is better then non is it not ????

Re - reading his post , I've realised that he wanted someone to remove it from the car for him. His Facebook post stated that a mobile mechanic had to be called to remove it and noticed a ball joint was worn so it would have been a waste of time just knocking off the bush.

Personally I check everything to see what needs doing before starting the job, and if it is just the bush that needs replacing then I find it easier and quicker to leave the arm in place - with the right tools they are a doddle, but each to their own. :}
