All done, satifying job
Tricky getting the top securing ring on. Bottom is easy, just put it onto the boot first then slide it on to the balljoint.
Top one was another matter, finally had a brainwave, I had an old piece of plastic waste pipe just about the right size to slide the clip over, place it over the boot then gently ease it off the pipe and onto the boot.
Time for a bath and listen to TMS, should be declaring soon.
