I would p/u a rebuilt unit at the local parts store rather than trying to rebuild it.
Changing the pump is pretty straightforward, not too cramped. You will need a pulley puller and you will need to bleed the system after install. Don't forget to change the belt. Tip: if you register @ autozone.com, they offer step by step remove/replace instructions on most common part including the power steeringpump for your Astro. Hope this helps.
Hello altgraph1: My name is Roger and I can help. The power steering and the brakes are directly connected. If the power steering pump fails you will also loose the brake assist. This vehicle does not have a vacuum booster you have a hydro-boost brake system. This unit uses the power steering pressure to assist the stopping of the vehicle. You will need special tools to determine if the power steering pump failed or if the hydro-boost system failed. Most likely the power steering pump failed. How ever to be sure it should be tested first. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger
on the astro vans they used a hydroboost power brake booster which is driven off the power sterring pump. If you are having brake and steering problems you should check to make sure your belt is still on if it is you probably need a new powersteering pump. You may also check your power sterring pump pulley.if this helps please rate
Mine just did same (2001). Have them check the power steering pump--shaft broke in mine. This affects the brakes as well since both power brakes and power steering run off same system in Astros. Broken shaft messed up the booster system.
