i have a suspension sweak in the rear.. it is only when i hit bumps at a slow speed, or when the truck is on the rebound after braking.. i replaced the shocks last year, and just a couple of months a go, it started squeaking.. any suggestions on how to stop this noise?

 

could be a spring shackle. could be a bad shock.
or it could be the springs squeeking.

have someone stand in the bed and jump up and down, get under it and figgure out what it is.

 

if it make a difference.. i have a 1990 ranger ext. cab 2.9 4x4.. could it be the leaf springs?
