If your Suburban has "hydroboost" brakes then the problem might be in that unit. Look on the firewall where you would add brake fluid. If there is a large round disk with a vacum hose attached to it then you DON'T have hydroboost. If it has two lines that come and go from the Power steering pump, then you do. You might just need to bleed the air out. With the engine running, turn the steering wheel all the way to the right and then all the way to the left about 10 times. Then look at the resevoir on the pump.

Why does my Steering whine and difficult to turn?


Power steering pump. If the gears in the pump become worn or "galled" the pump will whine and it will be harder to steer until the pump is replaced. **Check the power steering fluid level first. If it's low add to the correct amount. This may help if it's just low on fluid. If this doesn't help it is probably new pump time.

Lost power steering, then car wouldn't start


What is the condition of the serpentine belt? Is the belt free of oil or coolant? Is the belt tensioner working correctly? If the spring inside the belt tensioner becomes worn. It can not apply enough tension to the belt. Also if the tensioner is corroded it can become seized and cause the same problem. I hope this helps but if not please try to give more symptoms or details. Good luck.

Sound like you may need a new power steering pump or rack and pinion. Have you noticed any leaks from the vehicle? If you've had the vehicle for 21yrs, then I would have to go with the power steering pump is begining to fail. Hope this helps.
