It’s the same size as the Jeep’s axle nut, maybe 34 mm IIRC. If you have done your wheel bearings or changed a CV before, you already have it.
Just replaced the one I did eight years ago. (47,000 miles on the Jeep in that time.) I can confirm it is 34 mm. This was only the second time I've had it out of the toolbox! :D
