ARB Diff cover oil level

[1Seekingzen]

ARB Diff question. Not long ago I had an ARB Diff cover put on my 2024 Mojave to help reduce towing temperatures. The installer it DID NOT mark the dip stick, so I have no idea of the correct oil level. Does anyone else have an ARB, and how far up the dip stick should the level be?

I have the Yukon and I filled it to the edge of the fill hole. Right or wrong. We will see I guess lol. At least it’s fresh fluid now. The old was burnt and black looking from breaking in new gears.

ARB cover fill hole is probably 2"+ higher than what it is on a Yukon cover. He would probably blow out axle seals filling it that high.

So it looks like the level would be to the top of the bolt head directly to the right or left of the lower fill hole. You'll have to hold up the dip stick at the same height it will be when installed, and estimate where to file a mark. A little bit off probably won't hurt.

How would the ARB cover help reduce towing temps? Generally speaking, ARB covers hold less oil than the factory covers. I would think you would want to switch to an aluminum cover with cooling fins.
