Nothing goes as easy as the video's
The product is great but getting the old liner out can be a challenge. Top two hing liners came out with little resistance but the two bottom liners were not happy to leave. I couldn't even get the removal tool to work on them I had to use a small screw driver to chisel and peel them out. 2003 TJ don't wait too long to replace the liners.
Good advice Cebe, the sooner you can tackle these on your Jeep the better!
