What\'s that squeak?

I hear a squeak coming from under the chassis in the rear while I am coasting at around 35-50mph. The last time this happened it got very loud and I had to get my rear drive train rebuilt. The drive train was checked and it is OK, but I still hear the squeak and it is ANNOYING!

Any advice on what to check?
Thanks in advance.

>>>>If the squeak speeds up and slows down with the speed of the vehicle it is probably a driveshaft universal joint on its way out. A dry bearing cup is what starts the squeak and this turns the bearings into dust and eventually breaks the joint. Try lubing it, if it is greasable, or check for play in the joint. Warning: a bad joint will be very hot after driving on it-be careful. Laters.

Seems like a lot of people overlook this, but the front (double cardan) u joint has a hidden fitting near the center, which can only be lubed with a good needle nose attachment. If it goes dry, it squeaks like crazy and it burns up the centering ball. Result: rebuild the driveshaft. The fitting is not an ordinary zerc. You really have to look for it.
