Truck developed what I now know to be the Death Wobble. Front end would shake violently when I hit a pothole or was on a bumpy road. Took it to the dealership for inspection and asked them to check the wobble. They said the driver's side strut was leaking and needed replaced. It was covered under my extended warranty, otherwise it would've been about $450. That fixed the problem for a while, but then it started to come back about 6 months later. Had it to the dealership again for a recall and asked them to check the other strut. Said the other strut was fine. Traded the truck.
