At about 35 mph, the front end of my truck starts to bounce. Not extremely rough, but enough for it to be annoying. Im thinking its the front shocks. Any ideas on what could be causing it and what could fix it?

 

Check u-joints, wheel balance, brake rotors

 

How worn are your tires?

 

Less than 6 months old. Barely worn at all.

 

when you are braking or accelerating, or at cruising

 

Just front? Are the front tires balanced right?

 

Does your truck ride like a trampoline? When hitting a big bump, does the truck bounce more than 2 times? Do you see any fluid leaking from the shocks?

I think he's referring to the front bouncing up and down, not a resonating vibration.

 

He said at around 35 mph.

 

Just from driving and starting around 35 mph though? What would bounce the shocks like that (as far as the truck itself, not road condition) while driving that speed?

 

About 6 months ago I got the front end aligned, new driver side upper and lower ball joints, and a new steering gear box. It bounces more than its supposed to when I go over bumps, but not more than twice. It bounces at 35mph and quits when i accelerate or brake. Its only at 35mph though, not any other speed.
