I was really curious just how much this hunk of junk axle and torque tube setup weighs, so I bought a 700 pound scale to hang off of my engine hoist point in my garage ceiling (I planned ahead when I built the garage). I weighed both the 1957 Buick set-up and the 1994 Jaguar IRS.......

Guess whose completely different differential, driveshaft, braking system, suspension system, blah blah blah, made in 2 different countries (USA vs England), 37 years apart, weighed within 3 pounds of each other??? Take a wild guess...They couldn't be any more different.... and yet one weighs 350 pounds (Jag) and the other one (Buick) weighs 353 pounds!!!!

NO WAYYYYYY. That is seriously crazy! 3 pounds! You couldn't have done that in a million years if you told 2 engineers to design completely opposite assemblies but they must weigh within 3 pounds of one another.

Hey, at least I'm saving 3 pounds.
