Monthly for me and mine stopped once and I noticed somehow in the Jeep Uconnect app it listed my Jeep twice which jammed things up. Had to call them to get one of them removed and things went back to normal. And I think the duplicate happened when I extended my coverage after the 1st year
35’s and 4.1 you are ok and don’t really need to re gear but if you go bigger then I would and I’m actually going to go from 35’s back down to 33 on my Mojave when these wear out
I used to have one of these and it’s super light
