Thanks Grigg,
I don't remember reading about the 2 factor, that should be a lot better. I left my truck up on my jack stands. Both wheels are up. When I turned the wheels with both wheels free, the axle would turn slightly and then just quit turning, so I stopped one wheel and did the test turning the axle several times getting the 1.50 ratio, so I just double that and I have it. I'll also check it again later. Thanks a lot, I really appreciate your help. So, the weakness in pulling may not be a torque issue, it may be from lost hp in the engine, like I said, it needs rebuilding, black oil coming out of passenger side tail pipe.
Again,
Thanks alot
Joseph
