I've taken apart my power steering column on my 2600 to correct a steering issue. Last time I took it on the highway it would make dramatic lane changes. Scary!! I sensed that the problem was in the control valve area as all other steering components were tight. After removing steering column I disassembled it. Sure enough, the spring washer has self destructed causing excessive play. My probem was that after I removed the control valve the pistons and springs etc fell out. What I'm looking for is a diagram of the correct placement of the components. Any good pictures to refer to? Thanks...Per
