How to Install an Alignment Bolt in a Nissan Frontier

The alignment bolt or adjuster bolt connects the truck's torsion bar to the rest of the suspension. The exact installation of the bolt is pivotal, as it determines the ride height of the vehicle. The ride height of your Nissan Frontier has to be within a certain range for safe handling. The procedure and specifications can vary depending on the year of the truck and whether it has two- or four-wheel-drive. Talk with your mechanic beforehand.

Instructions

1

Raise the truck and support it on jack stands.

2

Lubricate the alignment bolt's threads with grease.

3

Raise and slide the torsion bar over the cross-member, slide the bar into the torque arm, then slide the bar backward and connect the anchor arm to the cross-member with its bolts and your wrench.

4

Slide the alignment bolt through the bracket holes on the anchor arm and the cross-member and screw it into place with the wrench. Install and tighten the bolt's pivot and adjusting nuts.

5

Lower the truck off the jack stands and then bounce the the truck on its front end and shake it to stabilize the suspension.

6

Measure and record the distance from the lower control arm's pivot bolt to the ground, then measure the distance from the ground to the rearmost bolt connecting the tension rod to the lower control arm.

7

Subtract the second measured distance from the first one to get the truck's ride height. It needs to be between 38 and 42 mm on most Frontier trucks.

8

Tighten or loosen the adjuster nut on the bolt as needed to get the necessary ride height.

9

Connect the lock nut to the bolt with your wrench.
