Hi Everyone. I've got a lurking issue that I hope someone here can help identify...
2012 Limited. 4WD. 3.31 gears.
Grinding noise when rolling... like wheel bearing, but more steady and does not get loader when loaded in turn - BUT did get loud when I hit pot-hole on pass side.
Noise gets MUCH louder when switched to any 4WD mode.
Had a drip from pass front axle seal that was metallic - so i thought it was obviously the source of my problem. Took pass side apart and replaced bearing and seal on output of front diff (changed oil)... noise still there
Soooo, the metallic drip still makes me think something in the diff... but the diff is fully 'disconnected' in 2WD? So why still grinding just not as loud?
Could it be a wheel bearing and just doesn't sound like normal failing wheel bearing?
Could it be a bearing in center diff?
Is front diff still driven, just hubs unlocked, in 2WD?
Thanks guys. I just don't want to tear into the other axle if I don't have to.
