diff fluid

[jdmustang82]

hello i was just trying to find some info on what type of diff fluid i should use for the front and rear axles on my 1970 bronco, i can get royal purple from work for a great price but is it okay to use 70w140 or should i use 80 90?

Hi JD.., welcome....

What Bronc76 said plus....

Do fill in your signature info. (see mine below) so as to rec. accurate future help.

For example., it's unknown what axles you have so it's "assumed" they're stock.

However., they could have "POSI" in which case, they need the additive to the 80w90.

The sig. should contain all that you know about your rig.., & can be updated at any time.

It will show automatically on all your posts. >< <'>
