A few axle swap questions

[tracker8wr]

I am swapping in a rear with 3.55s mine had 4.10s. Do I just plug the harness into the VSS sensor on the new axle or do I have to swap out the sensor.

Next filling the oil, where do i put it in and where do i I check it to make sure it is full. I pulled the cover and there is no fill hole on the cover. Do I put the oil in through the VSS plug. Any help would be appreciated.

Oh and why r the cover so dang thin if u hit anything Ur gears r done.

There is a check/fill plug on the driver's side of the case. Sensors should be the same.
You can install a '08 and up aluminum cover and ditch the stamped steel one.

thanks for the info went out and found the fill plug. Plugs r the same on the sensors. i will plug it up and see how it works. to remove the rear hub do i need a special tool for the rear nut. I asume it is something like what is used on a front axle with the four prongs sticking out of the socket. Is there a torque spec for this nut or just until its tight and spins freely.

same socket front and rear and the drivers side is reverse threaded (at least on mine it was)

k thanks. i am going to replace the seals and bearing in the rear before i put it in the truck. also check the backlash. looks good.

Most parts stores should have the socket, looks like this:



From the Service manual: torque spec:
Critical Torque Information: After tightening hub nut to 75-88 N-m (55-65
lb-ft), ratchet back eight teeth or notches on the hub nut (1/6 turn).
Eight clicks must be heard during this operation in order to have
performed it correctly.

So how about a question about the front 60 swap. What off of my ttb 50 can I use on the 60. I'm guessing spindle, hub and disc brake. Anything else.
