UPDATE 1.
removed lower arms and commented to replace bushes using 'C' clamp type tool. This removed the large flat bush but I could not press a replacement in... so got two new lower arms. Pressed out the lower ball joints, quite hard work, the hardest breaking the joint between the ball joint and lower arm, tried all sorts of techniques ( not heat), pick axe worked best for me.
So arms, ball joints, link arms new pads ( serviced slide pins) and re -assemble. Note- put the lower arms in first making sure the tie bars are in the correct upward position. Getting the ball joint into lower arm was fiddly as the joint is tight when new.
Test drive - laden vehicle at various speeds - all good, quiet over minor pot holes, like new!
Sone tips I used. There's no need to remove wheel hub ( danger of damaging ABS sensor) , detach abs wire from outer wheel hub. Detach hub from drive shaft and strut, rorate 180 degrees loose blot one hole of hub back onto strut and support the, now facing downward,disc on axel stands. This allows you to wind the pressure on the C clamp extractor tool to press the ball joint out and back in again.
Don't put anything on slider pins that will attack the rubber dust boots and don't put to much lube on the pins.
