Well there are 2 joints and the propper way to check them is to take out the d/s. If the jiont is seized, you won't feel it by checking it installed in the car. Could be something in the diff as well.

Yea i just checked it on the car.

You need to take it off and check it. You won't feel a frozen joint on the car.

Is there something that usually goes bad in the rear end??

soulds like you may have a posi issue..adding a bottle of fiction modiflier should cure it

Yea the fluid in there is prob from '91. It still works tho, just tested it out in a parking lot the other day.
