Install/replace Auto Leaf Springs

Signs That Your Truck or Trailer’s Leaf Springs Need to Be Replaced

If you’re experiencing a bumpy ride, or if your truck or trailer seems out of balance, it could be time to replace the leaf springs. Other signs that your leaf springs need to be replaced include:

Visible cracks in the metal

Broken leaf spring on trailer

Sagging in the back

Slouching on one side

Corrosion

Excessive bounce

Squeaky sounds while in motion

When replacing leaf springs, the front end of the leaf spring is installed before the rear end:

1. Raise the front end of the leaf spring to a level between the forward mounts.
2. Slide the bolt into place and secure it with the locking nut.
3. Bring down the back end until it makes contact with the spring and put the center into alignment.
4. Put the new U-bolts into place.
5. Tighten the nuts and bolts with a torque wrench.
6. Reapply the shock absorbers.

Here are some other tips for replacing leaf springs:

• Check the nuts and bolts again after about seven days to make sure they are tight enough.
• Repeat the steps on the other side.
• The type of vehicle and the type of leaf springs it uses will determine how often they should be replaced.
• Leaf springs may need to be replaced in pairs if the undamaged leaf spring appears to be aged or worn.
