for the last few months the rear arm would only work 1 lever at a time today theres no control as soon as you loose pressure it drops right away
been told its the spool valve
do i have to remove the valve block from the frame to replace rubbers or can i do it in place

I wonder if you can get some pressure tests carried out? If a spool is damaged it will generally be unrepairable. The spools rely on a close tolerance fit with spool and the chest.
