A work colleague has just bought his first van to try out vanning it is a 1990? ACE Jubilee Rallyman ? what chassis will this have because it seems one corner steady when wound down doesnt 'hold' so I suspect either the shaft or the nut that moves along it are damaged.Whilst i have removed these myself in the past it was over 20 years ago so remind me how to take it apart,does the steady have to be removed from the van and are parts available freely.
