Rear Diff fluid change

Took the Forum advice - I ordered the Ravenol 75/85 Diff fluid and plan to change front and rear fluid as soon as the 100 degree Humidity take a break .

Is there enough room to refill the Diffs with the Ravenol spouts or do I need to figure out a pump system ?

Thank you for any and all help

 

Rear diff can be poured directly from bottle. Front and transfer needs a pump.

 

I used a pump on the front a rear diff. O the TC, I used the ravenous spout and it worked perfectly. The rear would be easy with it.

 

Transfer case you can do with the spout easy

 

If changing at 30k i just use plain jane oil. How many owners of the big 3 ever change diff oil? I did on some of my Fords at 100k if they made it far.

 

I used Red Line and had a tough time in the rear because of the bottle shape. Might as well pick up a $5 pump while you're getting your gear oil.

 

The problem I see is the Ravenol Bottles are a weird size top and a traditional pump isnt going to fit . What have others done when using the Ravenol products ?

 

I recommend getting a halfway decent pump for the job. I bought a cheapo pump off of Amazon when I did my front and rear diffs and it took sooooo many pumps to empty each bottle. My forearms looked like popeye by the time I was done, it was miserable.

 

This^^^^^

I used a transfer pump for the diffs using Penzoil and was slap wore out. To my luck, the Revenol is a different size so i had to use the spout in the bottle. SOOO Glad it dit. It works great. For reference, it is a flexible tube that extends probably 4-6" from the top.
