Hey I do have a question we're is the rear differential breather and filter. How would you access them, do you need to remove anything while the differential is installed to access the breather line?
Primarily I am doing wading improvements and want to raise the location of all the breather filter and hose inlets so when submerged in water they don't suck in any water on cooling down.
Happy to help. The breather is attached to the fuel filler neck. To access, you need to remove the rear, passenger-side splash shield. There was no filter on mine, but it should look like the one under the hood by the coolant overflow.
The splash shield is the only thing you need to remove. The breather line is pretty accessible on the top of the rear diff if you want to replace the whole line. I ended up just using an ARB-knockoff breather and used the stock line.
As far as increasing wading depth, and if I remember correctly, the breather is as high as it can go--without getting creative or moving the breather into the cabin.
You may be able to run an air line down from the fuel filler compartment and install the breather next to the gas gap though. That would gain you about 4 more inches. Moving it into the cabin could be as simple as extending the line to the rear bumper and routing the line up through one of the rear tail light grommets.
I hope that helps!
