Reasons to Check Your U-Bolts

Although extremely important, U-bolts may be one of the most overlooked components of the leaf spring suspension system. These invaluable pieces of the suspension can mean the difference between a well functioning system and failure that can lead to damage of the leaf springs they hold.

How Are U-Bolts Used?

A U-bolt is a bolt that is threaded at both ends and is shaped like the letter “U”, but can come in a round U shape, a square U shape or a semi-round U shape depending on the needs of the suspension. It is one of the major parts of the leaf spring suspension and provides a permanent tie between the spring leaves. U-Bolts go around the axle and hold the leaf spring bundle tightly on the underside of the axle.

This is especially important if the leaf springs do not have spring clips to securely hold the leaves together in the bundle. By tightly holding the leaf spring against the axle, the springs can then absorb the shock that is applied to your suspension when your wheels go over rough terrain since the shock will be transferred from the axle to the springs.

What Can go Wrong with U-Bolts?

Like any bolt, the biggest problem that can happen with a U-bolt is for the nut to become loose. This is made easier by the fact that the suspension system and the U-bolts within it are constantly subjected to vibrations and jolts when you are driving. When the nuts become loose, a couple of things can happen. The first of which is that the U-bolt itself can start hitting against the axle. It is designed to be tightly held against the leaf spring, and this constant striking can lead to bolt breakage.

Secondly, even if the bolts are not to the point of rattling around, they can become slack resulting in the shorter leaf springs within the leaf spring bundle to move sideways. If caught early, you can tap the leaf springs back into place and re-tighten the U-bolts, but if left unattended, this can allow your leaf springs to become disassembled.
