How much gear lube does my rear end hold?? I was thinking of filling it with Amsoil:--)

Just shy of 3 qts. With a Mag-Hytec is gets up around 7 to 8 quarts.

I think it's a little more than that, especially if you have 4X4. (Although I don't understand why the 4X4 takes more. )



See the following:

Referencing the URL above once again, what is meant by "carrier split 3. 73 and down, 4. 11 and up"?

jlccc As the gear ratio goes up ( numericaly ) the pinion tooth count usaully gets smaller as does the overall diameter, so the ring gear has to move closer to the pinion to make contact. Instead of having a really thick ring gear the manufacture will use different series case's with the ring gear flange in different locations to optimize how much ring gear material is used. The metal for the gears are more expensive and are very high grade,it is cheaper to make multiple carriers and use less gear metal.



I hope this helps.

Good luck finding lube for it. Royal Purple seems to be popular on the TDR. Napa is supposed to sell it but when I went in and asked for it, they did one of these...



Amsoil is popular too but when I checked on a group purchase site (wwcd2) for it, they said they don't make it for the 80.



You can always go to the stealer...

You can use the same lube for the dana 60,70 and 80. I'm using the series 2000 amsoil,so HTRDHLR you can use the amsoil 2000 series. I forgot to mention that I use the 75-95w. I wouldnt use the 75-140w unless you live in constant warm temps and if you r tow really heavy.

 

[HTRDHLR]

This stuff?

Yes,that is what I and a bunch of other people I know are using. happy hauling!

 

[HTRDHLR]

[HTRDHLR]

Hey I dont need any friction modifier in the rear end with the synthetic?? Do I

 

[Floor It]

No you shouldn't,it has it in there but some people have had some minor noise and put some in later. I wouldn't put any in right off. Drive it awhile,you'll be ok. If it starts to make a popping sound when you go around a corner then put some in.

The fill plug in the cover is located at a lower position on the 4x2 vs. the 4x4.

I have a thought on why the four wheel drives come w/ the fill plug in a higher location. It could be that the extra gear oil is needed when the truck is off road ( side hills or off camber situations ) and the gear oil goes down one of the axle tubes. The extra oil still keeps the gears and bearings wet and protected where the lower oil level in a two wheel drive might starve the gears of oil if it were in the same situation.

Just a thought .
