Let me know if this helps. Also, if you look at pic 16 (last pic) I included an exploded view so you can see how the power steering pump ties in with the brakes. I highlighted the power steering pump and brake master cylinder.

Take care and let me know if you need anything.

You are very welcome. Let me know if you run into trouble or have questions.

Take care,

No it does not come with with one. you will have to change it. Is the shaft coming out with it? the power steering shaft could be broken. or the pulley is worn to much.

This video shows you how to remove the pump and pulley

Please run down these guides and report back.

There is also a rear support bracket, you will have to remove the lower nut to get the pump off

See diagram below

Hydraulic System Bleeding.

1. Fill reservoir to correct level. Allow fluid to settle for no less than 2 minutes. Start engine and run for 30-60 seconds, then turn off. Check fluid level and add fluid (as necessary). Repeat procedure until fluid level in reservoir remains constant.

2. Raise and support vehicle with both front wheels off ground. Start engine. Turn wheels right and left, lightly contacting stops. Check fluid level and add fluid (as necessary).

3. Lower vehicle. Turn wheels right and left, slowly from lock to lock. Turn off engine. Check fluid level and add fluid (as necessary). Lt fluid is foamy, allow vehicle to sit for a few minutes and repeat bleeding procedure.

Okay, yes it could be but before I replace the pump. I would flush the system completely as it may be debris from the fluid.

I would get about two gallons of fluid and flush the system. You need to remove the return lines from the pump and put them in a bucket and run the engine and add the fluid as it is running. Run it until the fluid is clean and no debris.

If that does not resolve it, then yes, replace the pump.
