Finally got to installing the hitch last night. The WD40 worked perfectly. I have the 11 Journey and the Curtis 13335 (i think that's the number) hitch. Here are my comments:
- the two back rubber hangers and the two front are easy to get off; its the two inside rear ones that are trouble as the spare tire cover limits the room
- once the muffler is lowered, the installation of the hitch is easy and i was able to do by myself. I rested the hitch on the spare tire and loosely installed the passenger side first by screwing on the middle bolt first.
- the driver side was a little tougher as their is a wire harness that gets in the way. I had to pull this in towards the center of the car
- to reinstall the muffler, i started at the back and got the outside ones on first; then the two forward ones and finished with the rear inside ones (again hard to get too!)
- final note was that the spare tire doesn't go straight up anymore....the hitch gets in the way. What I did was pull the tire forward and up and over the hitch part that gets in the way. Then tighten it up all the way
Hope this helps!
