Rear diff fluid

If you are certain that the bearing is toast then just change it, no reason to think anymore about it. Then refill with the right oil.

BTW, I just changed my diff oil last month and syth 75-140 was 17.99 per quart. More than double the synth 80-90. Both Mobil1 products.

You can get Amsoil 75-140 for $11.70 a quart with preferred customer pricing!!

I can't be the only one who read the spec sheet in the manual...it says Dana 80 take 75w90, so you have it right.

Sorry to hijack but I'm about to replace my diff juice and I would like to be sure how much I need, what rear end should I have and how can I know for sure? How much oil should I buy to do the front and rear? Thanks!

In a pinch, I just put back in what was availible at my buddy's garage, which turned out to be 75/90wt. Took almost 2 gallons, and a dash of Posi additive.

What I want to know is if this is the right fluid, (I'm thinking it isn't, should it be 90/140 sinthetic?) and if I'm hurting the diff running the lighter wt fluid.

The reason for the fluid change in the first place was a noisy pinion bearing. I had the truck up on a lift to try to find drivetrain noise, and using a mechanic's stethascope, found the pinion bearing quite noisy. There was no metal in the fluid I drained out... looked real good. So I filled it back up with what we had there that nite.

Thanks for any feed back...
