gonna be changing front and rear diff fluid and transfer box oil this weekend. I have the mobil 1 syn. fluid with the extended nozzle. Is this all I need or am I going to have to use the pump like the tranny fluid change?
Just trying to have my material set up prior to starting.
Thanks.

 

The diffs are fine. But the Tcase can get messy and most use some kind of pump. Do you already have a pump? advance auto parts and sears sells some good pumps for under 10$.

 

X2 on a pump for the transfer case! Also, make sure you can open the filler plugs BEFORE draining. You'll have a problem if you drained and can't get the filler plug open...

I had a hell of a time opening the transfer case filler and took 3 trips to Autozone to get the right tools. Ended up using a 1/2" wobble extension connected to a 3" extension to get past the brake housing.

Secondly, I have read people braking the filler plugs on the diffs since they are plastic, so you either want to have some (brass) spares or just be careful not to mess them up. New O-rings are generally recommended as well when doing that job...

 

thanks. have everything but the O rings. will have to pick those up today!

 

You can use thread sealer tape on the drain plugs.
I highly recommend replacing the DII plastic fill plugs with metal ones.
Just take one of your drain plugs to The Home Depot and buy two of the same thing, plumbing supplies.
