Hey Mike, thanks for reaching out!

To replace the electric drum brakes on your 2021 Cherokee Grey Wolf I recommend using the etrailer Electric Trailer Brakes - Self-Adjusting # AKEBRK-35-SA so you only have to make the initial adjustment to the brakes and then check on then from time to time to make sure there is a slight drag when you spin the tires by hand.

If you're also needing to replace any of your hub drums I recommend the Easy Grease Trailer Hub and Drum Assembly for 3.5K Axles # AKHD-545-35-EZ-K which uses the common 5 on 4-1/2" bolt pattern.
