Re: Whine noise on acceleration
alright so update ……….
I took the belt off . While off, I started the engine to see if the noise was still present and it was . Then I unplugged the alternator with belt off and started the truck just to see if the alternator was playing any part in the whine but the whine was still present. I changed the belt put everything back together but the same whine is still present . The whine happens in PARK , DRIVE, REVERSE …. It is very faint while idealing and you probably wouldn't even notice If you were riding in it. As soon as you hit the gas in idle the pitch rises with the rpms. It absolutely sounds like a super charger.
I don't know what a transmission pump whine sounds like , but I posted the video to youtube and that's what someone was suggesting .
Im new to FJs but do they have any issues with timing chain guides? coming from an Xterra they were notorious for the whine from the guides and it sounds the same...
any suggestions ?
