Re: bad p/s pump, or possible clog?
Pump itself is pretty simple, fluid it uses is really light. they don't clog that i have ever heard of unless something gets in there that doesn't belong there, kind of hard to imagine but there have been folks that just drive around with the cap off, forgot to put it back on or something like that. obviously dirt, sand, stuff like that can kill a pump. if you have some kind of underlying issue affecting your steering that would make the pump work really hard that could make a difference in how long it lives or suddenly dies. if you do have some other steering problem that pump is not the only place you will see it, you will have uneven tire wear even though tires are properly inflated, pulls to one side, stuff like that. hope that helps.

The power steering pump has its own dip stick the transmision dip stick has nothing to do with your steering if you lift the bonnet and look straight at the engine the power steering pump is on the front right hand side black screw on cap the power steering repairs run roufley at this pump recon around £150 the steering box recon is £199 if you buy good second hand ones you can half that price possibly 3-4 hrs work depending on garage £30 per hr ish hope yhis helps ivan
no noise when turning and stiff steering is usually narrowed down to 2 things. a bad power steering pump or bad rack and pinion assembly. the rack and pinion is most of the time leaking fluid when it is bad, but you stated the fluid is good. I suggest to remove the power steering reservoir cap , start the engine and look inside the reservoir. the fluid should be swirling if the pump is working especially when turning the steering wheel. if the fluid isn' t moving then the pump is most likely bad.
YOU HAVE AIR IN THE POWER STEERING SYSTEM.YOU NEED TO BLEED POWER STEERING PUMP FIRST BEFORE DRIVING VECHICLE.CHECK POWER STEERING FLUID LEVEL ADD MORE POWER STEERING UNTIL REACH FULL COLD MARK..RAISE VECHICLE FRONT WHEELS OFF THE GROUND.START ENGINE LET IT IDLE WHILE TURNING STEERING WHEEL LEFT TO RIGHT NON STOP DONT LOCK OR STOP STEERING WHEEL KEEP TURNING IT SEVERAL TIMES CHECK POWER STEERING FLUID IF LOW ADD UNTIL YOU GET COLD MARK ON DIP STICK DONT OVER FILL POWER STEERING PUMP BLOW A SEAL.IF POWER STEERING FLUID LOOK TAN COLOR SYSTEM FULL OF AIR.TURN OFF IGNITION LET CAR SET FOR A WHILE CHECK FLUID LEVEL.IF STEERING WHEEL FEEL STIFF HARD TURNING DONT DRIVE CAR UNTIL YOU HAVE NORMAL STEERING.IF STILL HAVE AIR IN SYSTEM BLEED SYSTEM UNTIL AIR IS OUT.
If you have power steering, check for the following first:
Check for an adequate level of power steering fluid.
The power steering pump is bad, or the belt is broken.
The steering cylinder has bad piston seals.
In any design version, bad alignment, worn or under-lubricated front-end parts can increase steering force. These problems are more noticeable with manually-powered steering. I have not heard of any hard steering caused by a problem with the steering column, but I suppose it is possible.
CHANGING POWER STEERING PUMP YOU HAVE TO PLACE A DRAIN PAN UNDER THE VECHICLE. SIPHON OUT POWER STEERING FLUID WITH A SIPHONER DONT USE YOUR MOUTH TO SIPHON SWALLOWING POWER STEERING FLUID CAN BE FATAL MAKE YOU SICK.WHEN ALL POWER STEERING FLUID IS REMOVED FROM POWER STEERING PUMP.REMOVE DRIVE BELT.THEN REMOVE THE POWER STEERING PUMP.THEN YOU HAVE TO REMOVE THE POWER STEERING PUMP PULLEY THE NEW POWER STEERING PUMP DONT HAVE A PULLEY YOU HAVE TO HAVE REMOVE PULLEY FROM THE OLD POWER STEERING PUMP.YOU NEED A PUMP PULLEY REMOVER AND A PULLEY INSTALLER.YOU CAN TAKE OLD POWER STEERING PUMP AND NEW POWER STEERING PUMP TO A MACHINE SHOP.THEY WILL REMOVE PULLEY OFF OLD PUMP PRESS IT ON NEW POWER STEERING PUMP.THAT WOULD BE CHEAPER THAN BUYING THE PULLER AND INSTALLER.GO TO AUTO PARTS STORE BUY NEW HIGH PRESSURE LINE O RING GOES TO PRESSURE LINE GOING INTO POWER STEERING PUMP.ONCE YOU GET NEW PUMP READY PULLEY BEEN PRESSED ON.TAKE POWER STEERING PUMP HOME PUT IT ON. BLEED POWER STEERING SYSTEM.WHAT YOU DO WHEN YOU GET NEW PUMP INSTALLED HIGH PRESSURE LINE IN PLACE.PUMP BOLTED IN DRIVE BELT ON POUR POWER STEERING FLUID IN POWER STEERING PUMP UNTIL FLUID LEVEL STOP DROPPING AND YOUR LEVEL ON POWER STEERING DIP STICK AT COLD LEVEL.NOW START CAR UP LET IT IDLE FOR 3 MINUTES.THEN TURN OFF ENGINE CHECK POWER STEERING FLUID IF FLUID LEVEL DROP ADD LITTLE MORE UNTIL LEVEL ON DIP STICK ON COLD MARK DONT OVER FILL.NOW SAFELY RAISE SUPPORT FRONT OF VECHICLE. START THE ENGINE.TURN STEERING WHEEL FROM ALL THE WAY FROM LEFT TO RIGHT DONT STOP LOCK WHEEL .GO LEFT TO RIGHT SEVERAL TIMES.THEN TURN OFF ENGINE CHECK FLUID LEVEL.IF ALL IS GOOD LET VECHICLE BACK DOWN LET IT SIT FOR A WHILE CHECK FLUID AGAIN.DONT DRIVE VECHICLE IF POWER STEERING PUMP MAKE NOISES OR YOUR STEERING FEEL STIFF HARD TO TURN.JUST MAKE SURE FLUID LEVEL RIGHT AND DRIVE BELT TIGHT GOOD LUCK.
COULD BE A SIMPLE CLOG, AND THERE WERE SOME ISSUES WITH THE PLASTIC NIPPLE WHERE THE HOSE CONNECTS TO THE PUMP CRACKING OR EXPLODING IN SOME INSTANCES. IF YOU HEAR A WHINE OR FEEL VIBRATION THAT MATCHES THE SOUNDS WHILE TURNING YOUR PUMP MIGHT BE BAD, OR POSSIBLE THAT ANOTHER PULLEY BEARING IS BAD. REPLACE PUMP AND IM GUESSING YOULL HAVE YOUR TAHOE BACK THE WAY IT SHOULD BE.
