Unhappy ARB Diff covers 2011 rubicon unlimted

Hi, So I am trying to find some diff covers. Have the Dana 44's that came with the rubicon.

I found these: 0750003 - ARB Competition Differential Cover for Dana 44 Axle Assemblies - Quadratec

but they state: Will not fit Jeep® Wrangler Rubicon


Not sure if there is another version I should be looking for?

So I just got off the phone with ARB tech and they said the covers dont fit the DANA 44 on a rubicon, the lockers and ring and pinion may hit the cover.

I JUST got off the phone with ARB and they said it would require at least some griding to ensure you dont destroy the insides. Which is why they say NOT to install it on a Rubicon, since it could (and HAS) destroyed pieces inside.

I'd believe Dave @Northridge4x4 before a factory guy. Dave builds them like crazy over here and he'd be the first to say if there was an issue. Since he said no issues....

I understand what your are saying, and I am sure Dave is correct, nor am I doubting his knowledge or ability.

But the manufacture of the product, and their tech department, says not to install it on a Rubicon, due to recorded damage done to the stock lockers and electronics the cover has and can cause.

So I am supposed to not listen to them, because a few people here say they work fine, yet ARB says otherwise?

Maybe ARB is wrong or maybe it only happens under certain situations, or even worse, they are lieing just so you put in their lockers.

All I know is ARB told me on the phone, and he was reading off damage reports, the cover can cause damage.

Thats funny because when I bought mine the application showed 2007-2012 Wrangler (including Rubicon). I have had mine on for over 4k miles now and I did not have any fitment issues. This doesn't make any sense as the ring gear is what will come in contact with the cover and the ring gear is going to be the same size no matter whether it has a selectable locker or not.

ARB Diff Covers on JK Wrangler Rubicons

Hi guys,

I'm not sure where info to the contrary came from, but our Dana 44 diff cover does suit JK Wrangler Rubicon models as indicated in our application guides on-line. If anyone can attest to that it would have to be the boys at Northridge 4x4. They have done as many as they claim.

For the record, years ago we issued a cautionary press release to our stockists because we had some reports of broken electrical lines on factory Rubicon lockers and we wanted to investigate the issue. This was fully investigated and found to be attributed to one of 2 failure modes:

1 - blunt force trauma occurring during the cover install (literally snapping the electrical junction off accidentally while the cover is off and everything is exposed)

2 - dirt ingestion into the factory e-locker needle bearing causing the magnet housing to seize to the diff body and rotate the electrical junction into contact with either the housing or the cover (depending on what direction you were driving).

In either case, if you get somebody who knows what they are doing to fit your cover then you won't have a problem.

I hope that clarifies things.

I remember those threads a while ago, but haven't seen anything about it for a while (until now). So you didn't have to make any slight design modifications to make it for properly?

I am glad to hear this. And Based on the responses I was getting on the forum I assumed this had to be true, I will now order these.

What concerns me then, is why the people from the ARB Tech department do not have current information.

I am sorry if I have brought out mis-information, but in my defense, it was mis-information given to me by both ARB Tech and Quadratec.

We had some aftermarket panhard rods that were conflicting with the logo deck height, so we angled the logo deck back to add more clearance. That was external contact only and it was years back (2007). It didn't change the inside shape of the covers at all.

We have bolted them onto JK Rubicons for our local Jeep dealerships down here several times.

As I recall it was only a few people that complained, and it was only Rubicon owners, and they said their lockers were damaged.

Glad to hear it's a non-issue.

In regards to the ARB dana 44 differential cover for a 2013 jeep Rubicon. I'd like to purchase one, but I don't know the fluid volume of the cover. I understand that it has a dipstick to check and verify it is at the correct level, but I'm uncertain if the volume of the oil at the correct level is the same, greater than, or less than the factory volume. Factory volume being around (2.3 quarts) for the rear differential I believe

They need to make these things with a fill plug in the center and forget about the top plug.No worries over filling one that way.

is that even an issue? I honestly have not looked at a non lifted JK in a while but I dont see how it could be an issue. is the e-disco really that big?



yea the distance from the diff cover to the sway bar is probably measured in feet, are you sure you arent getting swaybar confused with drag link or tie rod or track bar?

Just to clarify I am talking about the rear diff cover!!!!!!!

Ok the bar directly behind the diff cover, I thought that was the swaybar. I spoke with ARB this morning and they say there cover uis about an inch thicker than the stock one. On some other forums I have read it tight but it will not interfere with thr up and down travel on the suspension. ARB did say that on the Rubicons it shopuld only fit withe atleast a 2" lift due to hitting the front of the ARB cover.
The ARB cover is aprox 3" thick.

What is the bar called that runs directly behide the diff cover???
