8 3/4 Diff install fluid and friction modifier question

[robl72]

Just installed my rebuilt 8 3/4 sure grip In my Charger..

When filling the fluid and modifier I spilled about a little less than 1 ounce out of the 4 ounce bottle of modifier.. Will the small amount of missing modifier make a big difference?

If It does and I need to buy another bottle can I put the whole bottle in or is too much modifier bad?

Also what’s the total amount of fluid needed for a completely dry 8 3/4 rear end? I put 2 quarts in and it does not appear to be up to
the full plug

Thank you!

You should be fine.

I ended up needing 2 bottles in my Bee rear end to get it to stop "spooling" on tight corners. Run what you've got and if have issues just suck a few ounces out and put another bottle in.

BTW... for next time..

I forgot to ask how much total fluid should the Diff take if it’s dry

Sorry, I just fill it 'till it starts dribbling out. I have a 5 gallon pail of gear oil and use an old pint squirt bottle to put it in.

Use the Ford Friction or Dana spier version only. You will know if it is correct will smell like ****, it is whale oil.
