Outer Limits 4x4 Board

Okay, after an extremely muddy trip offroad, Ive given the jeep a bit of a clean (still needs attention), ive encountered an annoying squeaky sound from my front drive shaft.

Weird thing is, it didnt start making the sound until after i cleaned under the rig.

Please listen to the recording. Click here to listen
Thats me spinning the passenger front wheel to get it squeaking.

Anyone know what this could be? Dirt or grime? Its it fanged?

By the way, this is what it looked like after the trip:







Cheers,

pump some grease into the unis, bet there full of water.

Sounds like a case of "angry sparrows" which commonly nest in the front driveshaft carden joint - although your sound file sounds like a chirpy happy little sparrow Reasonably common on TJs. Stock TJ unis are not externally greasable. You can try and wash the mud and crap out with a hose and apply some spray on lube but it may be case of pulling it apart and cleaning / greasing. I've had mine done a couple of times now.
