I was driving down I64 in Virginia (75mph) passing an 18 wheeler when I hit some rough pavement. My truck started to shake and vibrate bad. I somehow made it to the right shoulder without an incident. I got out and inspected all my rims and tires (ok), front right and left suspension (ok), no play in drive shafts. I climbed back in and finished my trip to include towing my wife’s horse to the vet. The truck drove like new. I have 44k, and have 6ply Brigestones( wife hated Michelins). The only other mod to my truck is a 250 front bumper, but it has been on my truck for over a year. Anyone have this happen?
