I looked for that at harbor freight based on your advice, but I could not find it. Having the 4 year old in tow complaining how bored he was did not help locate it.

 

Havent thought of a sprayer. mine holds a gallon. Did you warm the oil ? how long did it take?
On my front diff I connected a hose to the bottle ( just topping off after seal leak) and the lovely mrs. Slabrat held the bottle above the radiator and squeezed while I held the hose in the diff.
I am going to try your method. the 04 is due. No Mrs. involved

 

sprayer works great you can reach right over the transfer case to fill it from the rear.
them you put all the old stuff in the sprayer and spray the inside of your frame rails,
I did need to park on the grass for a couple of days.

 

Am I the only one seeing this sig and laughing at it?

 

I kind of let it slide

 

wow, didn't see that. in sig. ha.

also could get creativ. As a youngster, we created something like this.


made quick work of transfers, but got a little sloppy when oil got low and air would foam up the last bit and sputter and spray.
