2013 Express 2500 extended cargo. about 183k miles.

A few weeks ago, I drilled some holes into the floor of my van and installed plus nuts (basically riv-nuts). I thought I was very careful, and I really do not think I hit anything. I zip tied one wire out of the way temporarily.

A week later, I took it on a drive and noticed that the whole back of the van was vibrating pretty bad and the service stabilitrak warning light came on.

Today, I noticed my right rear was badly bulging in the middle of the tire. When I removed that tire, I noticed that a wire harness that was zip tied to something was loose. I zip tied it back but didn't look too close at it and put the spare tire on.

Took another ride, the vibration is 95% better, but the light is still coming on.

Anyone know how i can read the code/reason the lights coming on? Any chance it's related to that loose harness by right wheel? Any other suggestions/tips?

Thanks!

 

Alright, so I replaced the tires and the Service Stabiltrak warning has gone away.

I suspect that bulging tire was just rotating at a different speed than the other 3, which set off the stabilitrak light. Installing the spare didn't help since it was a basically an all terrain with full tread vs my worn all terrains that were down to 4/32nds.
