Depending on which rear axle you have the capacity is between 3-3.17 quarts and does take synthetic gear lube. A torque wrench would insure that all the bolts are tightened the same amount for less chance of leakage.
The bolts are to be torqued to 30 foot/pounds
I have not looked yet, but will I be able to acces thefill plug or will I need a pump?
How do I know which rear axle I have? Bought truck at auction for y 16 year old son. I paid $3,800 -it has 132,000 miles. I a just trying to fix it p for him.
I am not familiar with cars or terminolog,but very handy - carpentry, plumbing and electrical work mostly.
Three weeks ago I changed the upper control arm and ball joint on the passenger side. Also did front wheelhub bearings and breaks and rotors all around. I watched a You Tube video! then took the truck to get new tires and an alignment.
the fluid bottle usually come with a top you can attach a small piece of hose to in order to fill the differential back up.
There should be a tag in the glove box with a bunch of option numbers on it. The parts store should be able to tell which differential it is from the option number.
Sometimes YOU TUBE can be a big help!
