Grand Cherokee OWNERS: Service 4x4 System? How I fixed mine after blowing up my rear differential

Go give my IG   / iambigsteveodiy   a follow for behind the scenes and new content alerts!

I have been plagued with "Service 4x4" codes on and off for a year and a half and I just completed the next round of fix attempts to hopefully put this issue to bed. I replaced the motor for the ELSD in the rear diff, super easy as you will see.

In this video I talk about my story and why I am getting this DTC C148F1D code and the journey I took to fix the issue. It's a low-level technical talk which is good to keep in the back of your mind, but if you are facing a "Service 4x4" code on your dash, then this video may help you.

I bought this stuff with my own money, but using the Amazon Affiliate Links below will offer a kickback to me if you buy this product.
