Power steering pump replacement
 

I pulled the 4 nuts on the power steering pump and it did not come off the accessory drive that the 2 vacuum pumps are attached to. so I pulled the accessory drive with the power steering pump. I can't get them separated, can anyone tell me how to get the pump off?????????

Thanks.

PS this is a 1991 non intercooled, dual vacuum pump that is gear driven .

you need a press. i took mine to the loca 4x4 shop (my press is leaking hydraulic fluid) they did it in about 10 mins and charged me 25 bucks) i just took in the pump and they pressed it right off
