Oil level in 14 bolt?

[RodsRVF]

I have installed a 14 bolt rear end in my Blazer. I had to cut the pads and reweld them to get the angle right for the 6 in lift.

The question now is how much oil do I put in it and also what to do about checking the level since the "Fill to" hole is angled up quite a bit?

Thanks for help.

id just fill it until it comes out.... that is about it....

back it up your driveway and check it. Should be level enough

If the axle angle used to be parallel to the ground you would fill until the oil came back out the hole. Now that the hole is angled up, would I not be over filling it if I fill until it comes out of the hole?

if you back your truck up a hill or driveway, the pinion should be close enough to being parallel then fill er up. Its not going to matter by that much anyway.

Jack up one side of the axle, to get oil to the hubs, then the the other. Jack the right side up last and fill it with the right side jacked up. Should be around 4 quarts.

I say fill it to the fill hole level. Your pinion has bearings in it, it sits higher now, thus you need more oil to lubricate it...

I put 5 quarts in mine before it went under the truck. We filled it by pouring it in the diff housing while the cover was off. Since the bearings are lubed by the gear oil traveling down the axle tubes I do not feel you can overfill a 14FF unless it is coming out of the vent.
