A differential problem?

[KQS]

Hi All!

I'm a '89 Corvette owner in Hungary/Europe. During the last winter my car was stored outdoor under a car-cover due to free garage space limitations.. It was well below 30 F when i first time tried to get out my car from the ground. I've noticed the the rear wheels were sunk into the earth about 1-1,5 inches. When i tried to reversing i noticed that my left rear wheel didn't rotate! I left the car there, and next time i tried to get out (about 10F outside) was everything OK. Does it mean that somethig wrong with my DANA 36 diff or it was simply the cold weather?

I ask it now because i've just noticed that my right rear tire are totally worn but the left (which didn't rotated in february) is still has some patter (about 3-4 mm).

Any idea?

Thanks for the help.

Not park brakes

I never use the park brake on my car... The Park function of the automatic transmission is enough i think on a flat ground... I also think that something frozen in during the winter...

Does anybody knows any methot to check the diff works well?
