Steering is very stiff. I have bled the lines and replaced the fluid. Started doing it just now and then and now it does it all the time would it be my pump?

When you bled the lines again did you get air?

Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

Replace Power Steering Pump, seals are blown. As for your brakes, lines need to be bled and adjusted. When bleeding power brakes DO NOT Bleed While Engine Is Running! Doing so will result more problems. Suggest it be done by a certified mechanic at a brake shop such as Pep Boys or even Midas. If brakes are still hard then it may very well be your hydraulic pump ( big circular object connected to the brake master cylinder on the fire wall ) is no longer functioning and must be replaced (rarely happens but....)

The brake calipers need to be bled of the air in the lines or you will need to check the brake fluid.

It really sound like you are going to need a new clutch. If the slave or master cylinders were bad they would feel loose, a stiff pedal usually means something came apart in the pressure plate.

Try flushing the fluid,which you should be
doing every 3 years
Add a bottle of Lubgard for power steering or
what ever the dealer has
Use the correct MFG Fluid

Eventually you will replace the pump,
when you can no longer stand the noise.

Then steering rack most likely is about to fail
from not changing the fluid and is causing stiffness
and high pressure thus the noise

When you put p/w steering fluid in did you notice any leaks on or around p/w steering lines? Have you had to replace the fluid on a regular bases? The clicking noise while turning could be cv axles have you checked them?

It sounds as though your fluid is burnt
I would like to tell you,if you flushed it with new fluid,you would be good to go,but burnt fluid is the result of some kind of damage, that has to be corrected.
The pump my have gone bad,but what concerns me, is that the black fluid,will most certainly take out the steering rack.
When the fluid is burnt,you lost the ability to remove heat. ( I hope you do your trans fluid every 30,000 miles,I used to own a trans repair shop,as well as P/S Fluid)
The growling ,is either a bad pump,a pump under pressure,because the rack is shot and stiff,or now both.
Tip--Install a magnetic inline power steering filter,on the return line, after cooler and before pump,after you replace parts and absolutely have to flush out the burnt fluid and debris you now got.

the rack and pinion unit may have a pinhole leak

try checking solinoids
