Hey guys,
I'm trying to track down a noise and am wondering if anyone ran into this before:
I've got a 2005 and almost always drive it in AWD. Lately I noticed a rumbling noise that seems to come from the driver's front corner at highway speeds (over 100kph/60mph). Sounds like driving over rough pavement.
I checked the front end contact points and everything seems tight. Tires are nearly new and look fine (I will be rotating them soon but I don't think they are the issue).
So then the other day I switched to 2WD on the fly and the noise went away. Switched back to AWD and the noise/rumbling comes back.
I did some searches and found the exact opposite (noise in 2WD, goes away in AWD).
Just wondering if anyone had a similar problem or some suggestions on what to check.
Any advice much appreciated.
2nd EDIT: Done more testing and the symptoms are indeed as above. When cruising at hwy speed in 2WD, I switch into AWD, feel a bit of a load on the truck, and the noise starts. Switch back to 2WD and the noise goes away.
I'll be reading up on the AWD system to understand how it works, but in the mean time, if someone can suggest any pointers for what could be causing noise in the AWD system, that would help. Does the front driveshaft turn when in AWD (and no slippage) or only when slippage is detected? I'm wondering if maybe the cause of the noise is the u-joints (I checked for play and couldn't find any, but they could be on the verge of seizing).
3rd EDIT: I replaced the u-joints and the noise is gone.
