Yesterday took the 69 351 For a solid drive, during a very windy road the power steering was completely lost at idle (700rpm) when I got idle above 1000 it came back to normal.so:
still the same when cold
belts tight, good condition no oil on them ….so no slippage
No obvious oil leaks and quantity okay .
Do I just buy another pump or is there another thing to try first …..with thanks John
