Another can of worms

[LSGarage]

While everything was out of the drivetrain I decided to change the fluids in my differentials. Just to make sure I had 4.10's like the PO said I counted the ring & pinons. I have a 3.40 in the back and 4.10 in the front. This may have contributed to the original problem I had with the TC not wanting to stay in 4Hi. Everytime I open up something else its another can of worms. The 4.10 up front looks in better shape than the 3.40 out back but I would rather go with the lower ratio. Had to get this off my chest, no one around my house wants to hear another said story about my truck.
