I had an issue with my Spare shaking pretty badly once I installed my spare tire relocator that I fabbed up. I thought had anticipated on everything but, I was wrong. So I am going to show my resolution and maybe others will want to use the idea. I started with the stock bumpers and a section of PVC pipe inserted into them. They weren't staying in place due to the rubber being so soft and flexed really easy on a bump. Next I ordered a set of the Daystar bumpers and they too were to short and to my disappointment they tear really easily due to the foam material. So I wetted the split area and glued it with Gorilla glue.

 

Then I got the idea to cut them in half and cut the ends to fit inside 1.5" PVC. Before I inserted them in the pipe I wetted the cut side and put glue on the PVC. I let them cure and tested them on the tail gate and Viola' they worked great. So I pulled them out and gave them a shot of Truck bed liner and currently waiting for them to dry.

 

radiator hose slid over the factory isolators works like a champ

 

Interesting......got pics? debating on whether just plugging stock isolator holes with ACE bumper or trying to rig something up. Here's a virtual beer dedicated to you for the idea though.......

 

sorry no pics. I did this back when I had 33's on my 2007. I now have the Teraflex hinge.
