What weight gear oil? I'm looking at popping the cover this weekend as well due to a weeping from the pumpkin. Or, how do I find the preferred weight of gear oil? 2000 Dodge Ram Van 2500 standard length.
I would put 75/140 in it if it were mine. Probably calls for 80/90, if you go that route make sure it is GL-5. Inprefer the Synthetic myself.
I run 75/140 in the rear and my Jeep and 75/90 in the front. Maybe it’s 80/90 I forget just know it’s 90. Front doesn’t see the shear loads like the rear.
Depends on what kind of fitting it is. If it is the bolt through the brake line that has a washer no. If it is a tapered pipe fitting the yes, either pipe tape or a suitable silicone. (Not all silicone is suitible for gear oil)
So, axle BOM translates to a Ford 70/267, non limited slip. Interestingly the owner's manual says it's a 70/273... manual calls for 8.3 pints of 80w-90. Who can I ping to see if that's accurate or if Ford has updated that recommendation, and do I trust the manual given the axle ID doesn't match up? Also, anyone got the torque specs and pattern for the Dana 70 diff cover I could steal?
Just fill it close to the bottom of the fill hole. Torque the rear cover? Naw, just use the german torque wrench. This is where sealant works better than a gasket and why we use it.
Sweet, got a Lubelocker Dana 60 cover gasket as that's what they advise for a Dana 70... Don't fit...
So, story time... Ford lists the axle options the E450 could have shipped with in 2006, including a Dana 70 in 4.56, no limited slip. Axle tag matches that description so a gasket was ordered based on that. As posted, gasket doesn't fit. A bit more digging, the Dana PN stamped into the cover is for a Dana 80, try a Dana 80 gasket, lines right up. Ford never offered a Dana 80 on this rig. At some point this RV got an axle swap to a Dana 80, and whomever did the swap moved the axle tag over to the new axle. If I find that bastard I'll percussively re-educate them...
