I just bought my first Subaru about two months ago. It's been running well so far, it only has 56k on it. Any way, to the problem. I had it out in some snow the other day and got it stuck. While stuck I noticed only one tire on each axle was spinning. I was under the assumption the rear had a limited slip in it and would engage when the front began to slip. Am I wrong to assume that all 4 tires should be spinning, at least a little? It has a manual transmission.
