Have purchased a new set of springs, I take it it is just a case of undoing the top of the shock and the wishbone should drop enough to remove the spring.
Your ideas would be appreciated.
I take it you mean car on stands then a jack underneath the wishbone and undo the inner bolts then drop jack. Reverse to refit.
Do I leave the outer end/ball joint connected or leave on and lower the inner.
Yes. lower the whole wish bone, using a trolley jack or other.
Many do it that way when they do not have a MB spring compressor
