Hi I'm new to the forum I have a 05 Chev Silverado Z71. I been have a noise that reminds me of a power steering noise, but that has been replaced also the waterpump has been replace along with belts & tensioners as well to no avail still have the noise. The only thing i can tell you is that when accelartion occurs the noise picks up faster and slows when decleration happens. any ideas the guys at the shop don't know they waiting on tech guys from GM.
thanks

 

Could be the alternator or A/C compressor whining.... other than that I don't know. I have heard alternators start making whining racket when the bearings in them go bad.

 

Thanks 72 charger i have to get those items checked out will post later what happens

again thanks for the ideas

 

hey 72 charger i just got to checking to see if it was the alternator or aircondition compressor and well it appears to be the compressor. thank you very much you have helped me in few days, that the shop guys couldn't figure out in almost 3- 4 months any thank you again.

Happy new year to all
