Reading the Shop Manual it indicates that the rear end axle oil capacity is 2.5 qts (5 pints). Last night while I was refilling I pour 3 qts of oil and I am still under the fill plug. I am expecting needing approximately 1/2 a quart more. Granted that the center section is now a Truetrac instead of OEM, but I don't think this should make much of a difference in oil capacity. Also, I know my car when in the lift is 1" higher at the front, but again, I don't expect this too make such a large difference.
This probably explains the problem I had last year. Last year after I refilled it my pinion bearing went. I was expecting to need 2.5 quarts and at around that level I got a spill so I thought it was full. After the bearing went, I checked and I was able to pour one more quart in it, which showed me that I had underfilled it. I was confused because I never had a leak, but ultimately I had made a mistake when refilling it.
This said, could it be that my rear axle has a larger oil capacity. Since I bought my car 4 1/2 years ago I don't know if I have the original axle. I think the center section is original because it had the buck tag that matched the 3.00 gears that came with the car. Thoughts?
