My 96 is leaking gear oil into one of it's rear brake assemblies. How involved is it to change the seal on it. It's an automatic so I'm guessing it's a Dana-70 but not sure. thanks in advance for any help, cd

 

It's a very easy job.
There are some excellent instructions here for trucks with rear disc brakes.
Drums aren't much different, in fact they are easier.

You will need a 2-9/16" axle nut socket, most auto parts have them for a decent price.

 

And do yourself a favor....If you find a deep groove where the seal goes..Spend the $80 and get two speedy sleeves...I screwed around with cheap and expensive seals and it still leaked because I was being cheap...After wreaking a couple of $10 and $20 seals,brake pads and the time to take things apart...I learned to do it right the first time....
