So I have recently brought a manual 2006 Hilux, which is now creating a loud engine drone/ vibration.
It happens under load, between 1500 - 2000 rpm, only in gears 3, 4 and 5. It is the worse in 4th gear.
I have taken it to my mechanic, and he thought it would be the engine mounts, so I have replaced them, where nothing was resolved. Ive also recently had the diesel injectors replaced. I have had all new oil in the difs but the vibration is still there?
Does anyone have any idea where this vibration could be coming from??
