Could be. Jack the wheels up and give them a wiggle with your hands at 12 and 6. Have some one else looking under to see what's moving.
Could be wheel hubs.
Could be sticking calipers.
Could be a track bar. The brakes causing a weight shift....

Could be tie rod ends.
Could be control arm bushings.
Could be steering box.
Could be a midget under your truck smacking something with a hammer when you hit the brakes... Hey, you never know until you look right?

Yeah, it could be any number of things. Could even be the bushings in the control arms.
I'm assuming 4wheel drive here...
From what I know, here's some things to check.
To check ball joints:
1. jack up truck and place on jackstands
2. place a 4x4 about 6" away from the wheel
3. lay a prybar across the 4x4 and under the tire.
4. press down on the prybar putting pressure on the underside of the tire.
5. if there is vertical movement (not suspension compression), you got bad ball joints.
Track bar bushings: (This is tricky)
1. idle truck forward.
2. jab on brakes
3. have someone lay on ground next to truck so that they can see the pumpkin.
4. watch for the axle to twist when you brake.
Steering box:
1. with truck on the ground, start truck.
2. have someone saw the steering wheel back and forth about 1/4 turn each way.
3. watch the sector shaft that comes out of the steering box. It should twist, not tilt side to side.
Drag Link / Pitman arm
1. with truck on the ground, start truck.
2. have someone saw the steering wheel back and forth about 1/4 turn each way slowly.
3. watch for slack, etc in the drag link and pitman arm and even tie rods.
Wheel Bearings: (also see tie rod check procedure)
1. Jack truck up and place on jackstands.
2. grab tire at 9 and 3 o'clock.
3. alternate pulling from side to side.
4. if it moves, there's wear in the wheel bearings.
Trac Bar:
1. You shouldn't be able to move it.
Tie Rods.
1. While checking the wheel bearings and ball joints, have someone wiggle wheels and check for play in teh tie rod ends.
U Joints:
You'll know. clack clack clack...
Steering shaft:
I have no idea
Hope that helps.
