Aftermath from trip...

Well, after driving my truck for a few days I have began to notice a creeking noise from the front-end. It's only on acceleration in four-wheel-drive and it doesn't matter whether the transfer-case is in low range or high, it still makes the noise. I'm thinking that it may be the u-bolts loosened up and they are allowing the front axle to shift slightly on the axle perches or it could be the soft transfer-case mount that has maybe sagged enought to allow the double-cardan joint of the front driveline contact the transmission crossmember under torque. Either way its got to be fixed and I will this week find the root of the problem and try to correct it.
