How To Replace Leaf Spring Bushings

Leaf spring bushings allow the leaf springs to rotate and absorb the energy of vibrations. The bushings are used as a consumable for the leaf springs and we need to replace them in time to avoid wear and tear on the leaf springs as well as the tires.

LUEN will show you how to replace leaf spring bushings.

1.    Block the front wheels and raise the rear with a jack under the third member, lowering the vehicle onto stands under the frame.

2.    Keep the jack under the rear end. Do one end of a single spring at a time, removing the bolt securing the spring into the front pocket and/or the leaf spring and frame bolts on the rear shackle as required. This keeps the rear end properly located.

3.    Remove the bolt and lower the jack completely to perform the repair described below.

4.    Install the new rear shackle assembly, lower the vehicle, and torque the nuts/bolts to the specification found in the vehicle-specific repair manual for your car. Repeat on the other side.

5.    Assemble the Advance Auto Parts loaner suspension press on the leaf spring/shackle with the small end offset and pressing against both the inner and outer sleeves of the bushing but centered on the cup end.

6.    Crank down on the press with whatever you've got, whether that be a wrench, socket and ratchet combo, or an impact driver, until the bushing is released. Adjust the position of the press as needed as you go.

7.    Clean the inside of the shackle/leaf spring with fine sandpaper or a ball hone on a drill.

8.    Using the grease supplied with the kit, lube, and push the two poly bushing halves and inner sleeve into the part. You may need to squeeze it some with the press.

9.    Lube and press the OEM replacement bushings into the part by reversing the press used above.

10.    Reassemble the rear leaf spring/shackle assembly using the jack under the axle housing to raise or lower the housing as necessary to insert and tighten the bolt.

11.    Lower the jack completely to load the suspension. Torque the bolt(s) to the specification in the vehicle-specific repair manual for your vehicle.

12.    Go back to Step 3 and repeat Steps 4 to 9 as required to finish the job.

13.    Remove the stands and lower the vehicle. Double-check the torque on the leaf spring and shackle bolts. It's a good idea to recheck torque after about 200-250 miles.
