Before I get flamed for a question that has probably been answerd somewhere on here let me start by saying I searched and found a coupld of different answers and would like to know which I should follow...

I just got my Solid Diff Covers and would like to know how much and which type I should use in my front 30 and rear 44...

I found on Solid's site differnt numbers that I found on the forum and just want to get things right.

Thanks.

 

What he said but 44, 44.

 

this write-up should help you out:

be sure to read the comments towards the bottom as they list exact amounts needed.

 

I was talking to the mechanic working on my Jeep today - he was wondering if we needed to overfill my rear diff since the pinion is changed. He was concerned the change in angle wouldn't allow the gears to throw enough fluid towards the front of the diff. Any ideas if we should, and if so what amount?

 

if you have an aftermarket diff cover like a solid, then you do not need to worry about this as the fill hole takes into account the change in pinion. a stock cover would be low and it would be hard to fill it to where it needs to be.

nope, royal purple is good stuff but it is expensive. i like to use it myself

 

I wasn't concerned with the fill hole location as much as the coverage inside the diff - we were just a tad concerned that maybe the new pinion angle would affect the gears being properly lubed. Obviously the gears naturally throw the lube around, but I wasn't sure if the angle would affect the coverage since it changes where the level sits inside the differential. Am I making sense?

 

As long as the ring gear is getting into the gear oil, rest assured, EVERYTHING in that housing is gettin sloshed REAL good.

 

Flame me all you want, I fill mine til it comes out of the fill hole...

 

Is that exactly true. I was told that some oil had to be flung forward to lube the bearing where the pinion enters. But I don't know if this is true or not.

The question as to how much comes up with the ARB covers that I have because the fill hole is high and it has a dipstick. I like them becaause of the dipstick since after running in water I can pull the dipstick and chck for "milk". The shop that put the gears in put the covers on and they put a notch in the dipstick at the level of the factory fill hole.

Does it hurt to run a little extra, go a little higher on the dipstick. I've also been thinking of changing to Royal Purple. My understanding is that no additive is needed for Rubi's; only for JK's equipped with the Trac-Loc limited slip.

I just looked in the manual; it doesn't even give the amounts needed for the axles, transfer case or auto transmission. Does anybody know those amounts?

 

Thats what I figured too - but the tech had concerns, so I thought I'd run it by the committee.
