My friend's ranger has been squeaking (seems to be from the back part of the engine) for a while. It really only happens when you lightly accelerate on the freeway (without downshifting, just lugging the engine), and it's quite faint. The heavier the load, (turning the wheel, ac, etc.) the louder the squeak. It kind of pulses and as soon as I let off the accelerator it goes away. We already replaced the belt, idler pulley, and tensioner (however, I have read about de-glazing the pulleys, not sure how to do it or if it is even a consideration for the solution). We also replaced the camshaft synchronizer because IT was squeaking extremely loudly on a cold start and it even caused the car to surge, stall out, and every warning light on the dashboard to light up. It was replaced today by our local trusty mechanic because no matter how we tried, we could not get the new one to line up like the old one was removed (it would not slot down onto the oil pump shaft even though the body and notch lined up). Finally, the fuel trims are about +6% on both banks and I think this is causing the light surging and random misfire below 1500 rpm. I also believe that this combination of issues is causing the transmission to wait a long time to shift and kinda stumble into the next gear. I know this is a lot to ask but I have been after these fixes for a year to no avail. Any input or suggestions are greatly appreciated.
