OEM axle upgrade

[Mattgo6]

Hello,

I have a 2021 Jeep Wrangler Unlimited Willys. It currently has the M186 conventional differential front axle. I wanted to upgrade to a little more heavy duty axle with a locker. I was told about OEM part number 68585731AA which appears to be a standard width (non-Rubicon wide) front axle that is an M210 with locker and 4.10 gears.

Does anyone know if this axle would bolt in under my Jeep? I know I would have to get a switch and run power to the e-locker since I do not have the controls for it, but otherwise, would this fit?

My VIN is 1C4HJXDN5MW576605.

I don't know, but here's what Mopar parts catalog says that axle will fit.

@Mattgo6 It will only work if you regear your existing rear axle to match the 4.10 ratio of the one you want, or buy a complete set of M210/M220 axles in 4.10 ratio. Yours are currently 3.45, font and rear and you can't have mismatched ratios. There are no stock/mopar axles with 3.45 and lockers, front or rear, that I am aware of.
