Bly,

A thought for you. The clutches in the diff. only slide past one another when either one wheel spins, or when you are going around a corner. Going straight in and out of the garage, your wheels are both going the same speed, so the whole differential assembly rotates as one piece. Not even the spider gears move.

I'd have a look at your universal joints if I were you. A note for you on ujoints. When installed, the angles of the universal joints must match at both ends of the drive line and be absolutely in line with each other. First draw two parallel lines on paper, say an inch apart and 3 inches long. Next, draw a diagonal line from one to the other. Look at the angles, they both match. That's how the angles work. Next, look down the drive shaft like sighting down a rifle barrel. If the joints are not dead in line, there's a problem.

You have a pretty short drive line in your car and less margin for error than say a passenger sedan or a pickup which have long drivelines.

Put the rear end up on a floor jack and rotate a wheel too. Then you can look and listen at the same time. Don't get under the car though, unless you have axle stands under the axle housing.

Hope this helps,
