testing center diff

[Brett Dikeman <brett@pdikeman.ne.mediaone.net>]

Any way that a drivetrain/alignment shop can test the center differential
to make sure it is working properly?  Just curious...Boomer is going in
for a full alignment/on-car-balancing/check of all bushings...a general
checkup of the suspension system(I've asked them to look into the
clunk/play in the drivetrain; it's pretty bad...the car lurches if you
accelerate, then slow, accelerate, then slow...and each lurch is
accompanied by a clunk noise.)

Thx!
