I'm doing my rally 1964 'S' which has had the same cones since I built it in 1994. At that time, Hi-Lo's were not allowed on Group 2 rally cars, but they are now, so as I'm going to drive on another rally, for the first time in many years, I decided to fit new cones and Hi-Lo's all round.
Yes, I think I'll take the top arms off and check the bearings whilst I'm at it.
Today I removed the rear cones and struts ready for the new adjustable ones. With twin tanks I'm glad I built it with rectangular access holes in the rear seat back panel. I got both dampers undone in 10 minutes and the entire suspension removed in 45 minutes.
Lots more re-prep work to do as well.
Thanks for the advice,
