What type of oil should I put in my Dana 60 rear axle? It is not a limited slip. 80w90? Does it make a difference if I use synthetic or not?
It's for my 73 F-250 with 8100GVWR.

Thanks,

ps how many liters/quarts do I need?

 

I believe it holds 3 quarts. I use synthetic 80w-90 in mine. Just make sure you park level and fill it up until it is level with the fill hole. Some people will park it down hill and "overfill" it, this is detrimental and will build excess heat so do not do that.

 

yup 3 quartz or six pints or 3/4 of a gallon. In this cold weather it is going to take forever to pump in. I like to jack the truck up really high on one side and remove an axle shaft then pour six pints down the tube.

 

I won't even ask how you change your motor oil lol.

 

LOL. I do that normal......I know the procedure is a little weird but I have done this enough in winter weather to know you can save about a an hour pouring it in over hand pumping it. that 90w is thick at these temperatures. In fact I just did it last week

 

Thanks,

Removing the shaft seems like a lot of work to me to, why don't you just warm up the oil in its cannister before you pump it in?

ps synthetic or regular, does that make a difference, except for the price?

 

I have nothing to warm a five gallon bucket of gear oil with, and I would be killed if i brought it in the house.

I would be willing to bet I can remove a axle and pour it in faster than you could pump it in by hand. It's really not that hard to pull a shaft and since I do a lot of towing of a 10,000lb trailer, i like to inspect them occasionally.

I run regular in mine. But I'm cheap. I would imagine that the synthetic is better, as it probably has better heat resistance/protection.

 

synthetic vs. regular. Well I've just replaced all of my gear oil from regular to synthetic, I can tell you I notice it in the tranny and transfer case because it shifts much easier in the cold. I have not had any increase in mpg, I have not had any increase in "leakyness" lol and I will never go back to regular gear oil. I'm certain it helps during cold weather lubrication as it flows a little easier. Plus the synthetic doesn't smell as bad either.

 

hahahahaha roflmao

 

I just replaced all my fluids in both my front and rear axles, tranny and transfer case. Used Lucas synthetic 80-90 in everything. I notice a big differance in the easy of shifting as well.
