clutch squeal on 1998 Toyota Tacoma

Truck is 4wd model. For the last 8 years the vehicle has been making an occasional squeal when engaging the clutch from a complete stop.
Never hear it when shifting while moving. Sounds like a dry bearing. This happens more often when going uphill. Had a co-worker with same truck and he said something about having his transmission split from engine and something retighten/retorqued. Also this problem does not seem to occur when vehicle is in 4wd, and happens more often the colder the temperature.

I have come across a similar problem usually starting off from dead cold in the morning, possibly intermittent. The pilot bearing in the end of the crankshaft that the input shaft of the transmission goes through goes bad. The bearing is about an inch in diameter.
