i just bought 99 4rnr sr5 and had to replace front right side strut,ball joint and cv axle.2days later i noticed steering fluid leaking from rack and pinion,checked the fluid level and it was boner dry and the fluid leaking was dark.can that be caused by the pump taking a crap?because i tried to pute some in and it took a little under a quart.just wanna know if its shot or how to tell? thanks fellers!
