Changing out my stock Aluminum diff with JBA's new Steel D30. This one's built with 4.10's and an ARB air locker.

Nice....

Worth it?

autoboy454 · May 15, 2010

is it just me, or should the fillport on that diffy be up higher... If it is a steel diff modeled after the D30A (we'll call it the D30S

) then isn't the fill level (bottom of fillhole) higher so that the passenger axletube has some gear lube in it to lubricate the outmost bearing in there?

Just an observation from a passerby...

The new fill is at the same height as the original fill hole (on the right). This is the center section from a D30S.

That will be one of the next mods I do.

Thats kinda my point exactly. I'm pretty sure the fluid fill levels are different for the D30A you find in all KJ's compared to a Dana 30 front axle found in Jeep YJ/TJ/XJ/...and the list goes on and on and on... lol.

Not quite getting your point. are you saying the the fluid level for a straight axle d30 not adequate if its re-purposed? The intermediate axle comes in at the same level as the full axle. The axle tube is exactly the same, just shorter. If the bearings were adequately lubed 2 ft farther out why wouldn't they be adequately lubed if they are little closer?

ThunderbirdJunkie · May 16, 2010
