smlducks

So i have noticed here lately whenever I am around 50-52 mph i start to feel a bounce. It comes from the rear of the truck, not the front and ceases as soon as I go 53mph or higher or 49 mph and lower? Does anyone else have this same problem? Any fixes?

My truck is an 04 with 87K miles and brand new tires and stock shocks.

stock shocks at 87k??? most likely you need to replace those already.... most shocks in the market come with 60k miles warranty.... you have to inspect those every 10k miles or so and how long it last would depend of basically how you drive and where you drive

is it possible those are due to the bounce?

Taildragger

87k? Yup, it is time for shocks, but that is not the cause.

smlducks

what else could be causing that then? is bounces while on the gas and off. New tires, properly balanced. 5.5 foot bed with toolbox and bed mat. Nothing else weird.

my 04 does it also. 79.5k on it.

ugh, its driving me insane.

Most 04 and up have a vibration around 50mph, due to imbalance of the drive shaft.

I have had two xcab and one supercab and they all had the problem. A coworker took his back to Ford with the same problem, Ford replace the drive shaft. I just live with it.
