Reply to "Driveline vibration after lowering car?"

Glad you nailed down the source of the vibration. I never meant to imply that U-joint can't work but that CV joints are more forgiving system. I don't know Pantera cars as well as others here but I doubt 0 degree camber is the optimum alignment for cornering using radials. Radials typically like at least a little bit of negative camber. If your car is just a cruiser without emphasis on cornering you're probably OK. Just be careful on those off camber high speed highway on ramps.

A powerful car with rear weight bias should have a rear suspension properly set up for the tires being used. Just my 2 cents.
