Replacement Fender Liners
I am not sure if this is the correct forum so please be patient.
As you might deduce from my other post, I have been speeding a few hours under my 99 Jeep Cherokee and discovered a couple of things. A fairly minor but potentially important thing is that at some time in the past, someone has cut a significant amount of the liner away. Not so much as to allow mud to get under the fender but water will now have direct access to the body cavity under the door. This is true for both driver and passenger front wheel wells. Unfortunately I have not found a supplier for these liners. I have found my local used parts suppliers to be rather unreliable.
