Changing front and rear diff fluid
My truck has 130,000 miles on it now, and has been through some rough wheeling, and lots of 4wd use during the winter. I think its about time to change the front and rear diff fluid, along with the Tcase fluid.
I have done a lot of searching and reading on how to do this... I found a nice how to on the changing the tcase fluid, so Im all set with that.
Now, from what I understand the front diff has a drain plug, and the rear does not. The front, I will be able to simply open the drain plug and the fluid will drain out, and i can screw the plug back in, and fill up fluid into the fill hole until it starts poring out, close it up and be all done.... Right?
The rear...I have to take off the cover in order to let the fluid drain... Right?
So after the fluids drained from the rear, I simply scrape the gasket (rubber? paper? liquid seal?) off of the diff and off of the cover. Then I purchase a new gasket from autozone and replace it and bolt back up the cover and fill with fluid from the top fill hole? ...Right?
Or is it different.... when I take off the cover is it a gasket that I replace? Or is there a "mote" (thinking of the trench around a castle" on the cover that will be filled with gasket sealer stuff, that I have to get out and refill.
Do I use locktight? What kind?
And Im assuming that all of the fluid types and capacities will be in my owners manual right? (not service manual)
Thanks for anyone who had the time to read and respond...I just want to make sure I do it right and dont have any problems its my dd and I have no spare vehicles, or money to pay a shop.
