SOUNDS LIKE A POWER STEERING PUMP NOISE, IF THAT IS NOT IT THEN IT IS THE FRONT PRESSURE PUMP IN THE TRANSMISSION.

SOURCE: 2004 chev silverado ext cab. No Power steering

Hi Hollings,

You description was very good, I need to ask for a specific.

When you turn to the left, the wheel is stiff like the engine is off or does it turn smoothly but the vehicle doesn't turn or seem to respond.

I'm trying to rule out broken mounts,

Also, if the wheel is all the way to the right, is it difficult turning back to the left the whole way, or half way. See where I'm going.?

Please comment back your findings

Best regards
Mike

normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.



oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.

Has to be a drive axle,most likely an inner joint,should be able to feel the play if one is bad (jacked up to let the wheel spin freely).
Also. If the front suspension is weak,or lowered, the CV axle will bottom out in the inner plunge cup and make a terrible vibration.
