I've got a question, not sure if it's a problem or not but I would rather address it now than find out that it was. I had my car on the lift last night to install a fuel pump, and my cousin was turning one of my back tires. After about 2-3 rounds the tire stops freewheeling and you have to use some force to turn it. Not a great deal, but it's not easy either. After a little more turning it freewheels more until it hits the spot again. Is this a potential problem? I had 3.73s and the trac-lok replaced at the end of may last year, and some moser axles put in around july. No problems thus far out of the rear end, no funny noises or anything. Just a slight leaking where the axle tubes join the differential.
