SOURCE: power steering pump blew a hose off and now whines.

Have you checked the level of fluid in the pump? If it is full, you may have damaged the pump with it ran low. Try a Power Steering Lubricant first but if it is full and still making noise it is time to replace.

There are a few models that use the power steering pump at the booster for the brakes, but I doubt that yours is that. Look at the brake master cylinder. If it has this big round black drum, you have a vacuum assist and there is no correlation. If it has a couple of hoses going to an item behind the master that look like the hoses on your power steering there may be a correlation. Most of the diesels had the power steering booster.

Hope this helps

How do I align the power steering pulley with all other pulleys on 2.8 liter Chevrolet engine?


Align it? The power steering pulley is pressed onto the pump assembly and should not need alignment. If it appears out of alignment, inspect the pump for proper mounting. I have seen the power steering pump shaft break internally inside the pump and cause the shaft/pulley to walk out. You can test for this by removing the belt and pulling on the pump pulley. If the shaft comes out. you will need a new pump

Power steering pump shaft broken again


When you place the wheel in a hard lock position ,the power steering pump relies on the pressure by-pass valve to operate instead of the valves in the steering box to open and allow the pressure to by-pass back to the reservoir.. When you hit hard lock and you hear the motor load up just ease on the turn and the pump will operate as designed. The turn will still be the same -just that the pump is not under full load . Breaking the shaft is a sign of excessive load and a misaligned pulley so check that the belt is directly in line and the pump is square to the belt line.

Does power steering pump have check valve,the hose from pump to coolant keeps breaking


Some of the SUVs/Pickups did have pressure relief valves, yes.
2002-2003 Envoys have a history of substandard steering pump quality, often with broken shafts involved. Recommend both pump and hoses be replaced. Some years had a formal recall of these components for power steering hose leakage/breakage as well. The leaks most often occur when braking while the wheel is turned all the way to one direction.

Power steering went out on a 2002 trailblazer. the serpentine belt was slipping off so I replaced the serpentine belt and pulley tensioner, still out. Pulled the steering pump, pulley shaft was broken....


Have you checked your tie rods? Possibility one is either bent or broken, I've seen it before on TB's. That pulley shaft is a common problem to break, especially when cold out. PS pumps/pulley shafts and tie rods will snap if doing donuts in the snow with the steering wheel cranked, or off-roading. The PS is completely mechanical, no fuses or relays.

Power steering not working tried adding power steering fluid didn't work.


The Pontiac power steering pump run off a shaft driven and not belt driven. This means that when the steering system is stressed instead of the belt slipping it puts a lot of stress on that shaft and could cause that to break. If nothing seems to effect the power steering I would have to guess that this is what happened and the power steering pump will have to be replaced.

On my 20001 chevy silverado 1500 Z71 engauged 4x4 and then steering wheel got hard so hard to steer desangauged still the problem persist


Sounds like a steering pump or steering gear problem. Remove Power sterring pump cap while engine is running and see if fluid is moving. GM's are bad about PS pump shafts breaking. If no fluid movement, Replace pS pump
