I've had her about 2.5 months now but finally got around to getting a level and some new tires on it last week. Went with a RC 2" level and 33x12.50x20 Cooper STTs.

Rough Country 2" leveling kit, Cooper Discoverer STT's 33x12.50x20.

I have noticed the same problem this week, and I'm at 2600 miles. Though I generally here it whenever I am going over a bump that torque the rear of the truck side to side, like pulling out into a road where there is a little rain ditch between the sidewalk and asphalt. Tonight I heard a louder pop and a slight jerk/vibration from under the bed when I started slowing down for a red-light. Got home and checked under the truck, didn't see anything out of whack and it had rode fine the rest of the way. Going to take it to my dealer tomorrow.

My seat has been doing the same thing as the OP's. Just started doing it about 100 miles ago (650 miles on the truck now). I'll try this and sees what happens.
