need new power steering pump on 1999 Chevrolet Express 1500

How much should it cost to replace a power steering pump and power steering gear box on a 1999 express van. A mechanic is quoting $900.00. This seems high to me.

According to the repairpal estimator link on the home page the pump is $300 to $485 and the gearbox is $350 to $775 depending on where you live. These estimates to not include taxes, disposal fess, etc. Some of the work will overlap with the bleeding of the system. Maybe even better access for the gearbox if pump removed and will have the hoses at each one off. May be a good guote. Get a second opinion.
