Sods Law

I've just been out for a blart, the weather is so inviting .Have developed a rubbing/slight knock from the rear ,mostly off load and when turning left The offside DS is not right ,bottom wishhbone caked in oil,clunks when rotated back and forth ,also the caliper is sticking like mad Would the caliper drag have speeded up the DS wear I knew it was a bit tight but hadn't really looked at it
The only solice I can take is all my now sold bits where nearside I think
DG 710 mm DS is offside
