About 2 months ago my power steering fluid went ow, so I filled it back up, now my power steering is holaring again, and the fluid is low again. The car has had a leak since day 1, any common weak spots?

the seal around the shaft is a common leak point on gm power steering pumps. other than pressing the pulley on and off, its a very simple job to swap one out. two lines and three bolts and it's in you hand.
