Hey guys, so I just got back from my camping trip... Thanks for all the responses! I decided to take the VX with me on my trip because the vibration went away and it was starting to go back to normal. I noticed that when I was on a hill at a stop light and going upward, I hit the gas and then the whole issue just went away... really perplexing. I'm thinking that the issue had to do with the 4Lo not being completely disengaged as was previously mentioned in this thread. Along with that, there is no vibration or whining noise anymore. I'm going to look into the front end before I ever use 4Lo again just to make sure it's lubed up good.

I don't have manual hubs as this VX is bone stock. I just thought that, by adding the switch, it would take care of the pulsing feeling. I don't think that this TOD switch really did anything though, as I found out that the switch was incorrectly wired in the first place and was still only connecting the blue wires together anyway.... hahaha.

Just for interest sake, what is the size difference between the 3 tyres, and the spare??
I believe that the spare I have on here is about 1/2 to 1 inch smaller than the rest. Plus, the tire place installed it on the rear passenger side... I asked them if it would be a better idea to install on one of the front sides because of the TOD system but they said no.. They were the stupid ones in the first place to puncture the original tire...!!
