have an 04 disco with 57300 miles and recently noticed a weird high pitch noise coming from the front end of the truck. the noise tends to get worse when i turn the steering wheel and is worse when the truck is cold just after startup. sounds like a straining loud high pitch sound everytime i hit the gas and turn the steering wheel. just noticed the noise about 2 days ago. any ideas? thanks in advance.

 

power steering pump,,,


try changing the fluid and see if that helps,,,

im betting you dont know if it has ever been done

 

Go look at your belt, good possibility would be a bad betl and with your mileage a new belt tensioner and 2 idler pulleys, all of which do fail and cause a whine.
With your mileage, it is time for a 60K at which time you should flush the p/s fluid along with everything else.

 

dang,,,,mike

i forgot the belt and pulleys. are the pulleys shot by the 60k mark?

 

Can be, I got mine replaced under my factory warranty while doing the 45K.
