Welcome to the forum.
Can you provide the part number for the entire rear knuckle assembly?
I can't figure which part is the bushing.
We have had a discussion about front steering knuckle ball joints and people were getting Moog ball joints.
I went to Mopar Online Parts and can't find what you are describing.
Refer to this Web site: Select Parts Category - 2014 Jeep Cherokee | Mopar Parts
Generally when Mopar sells an entire assembly it is because repairing it is not cost effective for the Jeep repair facility.
They also don't want to provide every "piece part" separately.
Sometimes we just have to spend the big bucks and do it the FCA way.
We have some Canadians on here that speak French if that helps.
Found this Web site: Polyurethane 240sx/Skyline Rear Knuckle bushings (pair)
Maybe you can find something that works.
Here is an adventurous link:

Apparently Moog makes bushings, maybe you can find one that fits.

I don't need it personally, but please provide it to other Forum members.

Sure looks expensive: 2014-2018 Jeep Cherokee Rear Knuckle, Left 05090073AE | Mopar Online Parts
According to my interpretation the bushings are not available separately.

Go to moparonlineparts.com and specify your VIN and then find the part you are looking for.
The site will say 'this part fits your vehicle'. Then you will be good to go.
Or, go to your local Jeep dealer and have them look up the part based on your VIN.
You will be able to buy the part online for a lot less than the dealer, even with tax and shipping.

What are you guys doing to wear out rear knuckle bushings?
I have 122k miles on my 2014 TH and go off road on some really bumpy terrain. I go really slow, 1.8 MPH using SSC or slower for the really bad spots.
I think my bushings are ok, how would I know if they aren't? Should I do a 4 wheel alignment and check the suspension? It has been awhile.

Thanks for the update. My tires have never worn unevenly. My Jeep dealer makes sure my alignment is done correctly.
And, I am really surprised the front and rear tires almost wear the same.
My Firestone tire dealer will rotate my tires fairly inexpensively, possibly free.
I replace my tires when they get down to 1/2 tread depth, I need really good traction on rocks and mud on my trails.
The suspension is firm and tight and doesn't make any 'funny' noises even when driving over the rough stuff.
When I go down my steep hill using HDC the brakes do a lot of moaning and groaning, I can tell they are working really hard.
