Suspension, truck keeps on swinging side by side when driving through a bump or going up speed?

Hi,

Have you checked to make sure there are no issues with the sway bar bushings (front and rear) and the stabilizer links?

I attached two pics below. Pic 1 shows the front and pic 2 is the rear. Check those things and let me know what you find. Additionally, let me know if you have checked the steering components as well.

Take care,

Joe

See pics below. Note: Sorry about the pics. The last two are correct.
