Installation Instruction for My 2007 4Runner Sway Bar

The Toyota 4Runner utilizes a sway bar for both the front and rear ends of the suspension. These are also called stabilizer bars or roll bars, as their purpose is to keep the vehicle stable so it won't roll over when making sharp turns. The most important components include the bar itself, the links that connect it to the frame and the bushings. Installing a sway bar on this unit can involve replacing the bar itself or installing the old bar with new bushings. The installation process is very similar for both ends of the truck.

Instructions

1

Make sure the truck's end is properly raised and supported on jack stands. If the rear end is raised, make sure the front wheels are blocked.

2

Insert the rubber bushings onto the sway bar, positioning them right up against the bar's bushing stopper.

3

Connect the stabilizer bar's support brackets to the bushings and then mount the bar onto the frame (front) or axle (rear) using the brackets, tightening their bolts with your torque wrench -- 30 foot pounds on the front bar, 22 on the rear.

4

Fasten the stabilizer bar links to the bar at each end, tightening the nuts to 52 foot pounds.

5

Connect the sway bar links to the steering knuckle for a front bar and tighten their nuts to 52 foot pounds, or connect them to the frame for a rear bar and tighten those nuts to 132 inch pounds.

6

Lower the truck off the jack stands.
