There's a chirping noise coming from the front driveshaft somewhere near the transfercase. There isn't any chirping sound when I jacked up the rear and spun the back tires. Does this sound like a bad joint, or driveshaft?

Also, is it safe to drive the vehicle when it's making this noise? I won't be able to take it to the driveline shop till Monday.

Pull it off and take a cap off. Look for scorching, or damage to the metal, or missing needle bearings.

I never had screeching before :confused:

I just changed the universal joint on my 85 4runner and before it went it was screeching like a baby. I still drove it around for about two weeks before I changed it though. Those needle bearings were toast. The squeeking is most likely a lack of lubrication and alot of rust (as mine were).
It is very likely your U-Joint.

Almost always you get a vibration before the chirping.
The chirping is your needle bearings turning to dust.
Grease wont help now.

If you can't feel slack in the u-joints by hand (in nuetral wheels scotched)
Take one end of the shaft loose.
and move each u-joint back and forth.
If it's hard to move in one direction, that's the joint with the problem.

BTW I had a vibration in mine for the last week, just didn't know which joint was bad. I pulled 2wd drive chevy up the hill yesterday in the snow. When I turned around you could hear it chirping. So last night I pulled the rear shaft and my upper was bad.

An idea you might try too, is to put a "witness" mark on the caps and yolks, and that way you can quickly and easily check to see if the cap has spun in the yolk.

take the front shaft off and replace the joints, mark ur drive shaft so u can put it back on the way it was so u dont get a vibration. and that should fix your problem
