If it is the radius arm bushings, here you go.
Raise and support front of vehicle. Support axle.
Disconnect lower end of shock absorber from shock lower bracket and remove front spring.
Remove the nut from rear of arm.
It is easier to replace the bushing if the arm is off the truck, so remove the front mounting bolts. If the rear mounr had bolts in it, remove the radius arm mount and replace the bushings there. You may need a jack to help manuver the arm.
Remove the arm and remove inside bushings.
