Default 98 3.0 humming noise

Hey,i have a 98 XLT Super cab 2x4 with a 3.0 ,has only 59k on it.Have a humming noise (similar to a low p/steer whine) that i hear at idle and slow speed.This is not the fuel pump,the noise sounds like at rear of engine or bell housing .Sound travels into drive shaft which has me stumped.Could this be a bad cam synchronizer ,I'm a Auto Tech and i know they usually chip.Any ideas ,Thanks !!

cam sync for sure, do not get the dorman kind, they are chinese brands and you will continue to have failure with them, You need to pick up the Cardone make as they have a great reputation and a high reliability, their is a write-up (How To) and the item location is held down by a single bolt and sits in the rear passenger side of the engine.

You just joined this site on the 3rd, and this is in no way making you look good on here by comments like that.
You have to give some people time man, SOME of us work and cant get on the computer, or maybe someone is trying to help you out by doing some research. There is no need to be like that, this site is good for advice and reccomendations, We are not here to be YOUR online mechanic. There is no need for insults and if you want to learn more about your ranger get some manuals and open the hood and take a look, because that how you learn through manuals, advice, and overall getting off your butt and looking yourself

Hmm, i've never heard of a cam sync humming. I thought it was usually a chirping because of the wobble. Is there even a way for the cam sync to hum?

The cam sync. didn't fix the noise.This is a humming noise that must be coming from the tranny ,if you put your ear to the driveshaft it sounds like it's coming from it.I'll try to record the sound and post it.Now i hate i got a dam automatic.

Sounds like a bearing howling .Only does it when it wants to,sometimes faint and sometimes loud at idle or low RPM.Have heard driving but at very low speeds.If doing it at idle it will only be heard around 800 to 1200 RPM.
