Guys, a newbie needs enlightenment.
Yesterday, I raised the rear of my vehicle (two wheels on jackstands off the ground, front wheels on the ground). When I turned one rear wheel, the other moved the opposite direction. I read somewhere that this was normal because of the viscous coupling in the differential.
Today, I did the same procedure on my dad's 1969 mustang. I noticed that turning the right rear wheel also turned the drive shaft, but the left rear wheel did not move at all. When I rotated the left rear wheel, neither the right rear wheel nor the drive shaft moved.
Is this normal? if it is, can someone explain to me why? If this is not normal, where could the issue be?
additional info: both cars are rear wheel drive.
Thanks in advance!
