F-250 rear diff change today

[FiremarshalRob]

I recently purchased a 2006 F-250 w/ 6.0L Diesel.
The rear diff had never been changed, so I went ahead and changed it today. Man it was pretty nasty and the drain plug had PLENTY of metals on it.

The owners manual calls for 6.9 pints of 75w-140. I replaced with 3 qts Valvoline Synpower (did not need added fricition modifier per Valvoline's website)and the level is high enough to where I can dip my pinky finger in the fill hole and reach the gear oil.

Do I need to go out and purchase another 14 dollar qt and fill to where it begins to leak out the fill hole, or just let it be with the 3 qts. I pull maybe 6 times a year. Is it going to overheat? Squeal?

 

[Jason2007]

I think you would be fine.

 

[VK56VD]

I fill mine up until fluid starts coming out.

 

[Jason2007]

if you must, just top it off with whatever is the cheapest you can find.

 

[hate2work]

Yeah, truthfully I think you would be fine. But if it was me, I'd fill it all the way.

What you might do is go ahead and buy the extra quart, fill it all the way, and then you'll have 1 pint left for the next time you drain and refill it, which you might want to do sooner than later because it was so dirty.

 

[Jimmy9190]

It will be fine the way it is. If you fill it all the way to the bottom of the filler hole it will saturate the plug and cause a leak. It won't leak much but it will leak and you will need a new plug. Happened to me a year ago.

Some rear axles should be below the plug threads. Go to Amsoils application guide on the right side of their website. Try to identify your axle in the guide. It will say if it needs to be lower than the lower threads.

Some rear ends must be more sensitive to fill levels. All I know is it's a pain to have to fill to a spec of 9/16 below fill plug. The dana Dodge I just did required that.

I used to just fill them till they started flowing out when I worked in shops. Never had anybody complain. But that does not mean it was the best to do on every rear end.

One thought is the level that is higher has more chance of leaking out of axles seals or seeping out of fill plugs like jimmy9190 mentions. +or- 1/2" might make a difference?

SERVICE INTERVAL

 

[Steelhead]

would you run permanently run your crankcase 2 quarts low on oil while towing?

add the last pint. save the rest of the bottle and change again in 15k.
examine again for high wear metal flakes. if bad, have a UOA run on the old lube and have a diff. shop examine diff for excessive wear and what is wearing.

a qt of diff lube is less than 1/50th the price of a ring/pinion replacement with setup labor.

 

[FiremarshalRob]

Thanks for the info.

I'll go ahead and purchase another qt and fill er up completely.
