Sounds like you have a 4:56 and it is a limited-slip. one wheel turns so far and then they both lock for traction to both.
Pproblem with the Dana/Spicer rear ends is that if they start to move the side bearings, the differential side bearings can start to wear the sides of the case, making it a piece of scrap meatal as it would be cheaper to replace the whole rear end than to have it machined :rolleyes:


There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!
