STEP 01

Assemble both sides loosely

Safely support the car and remove both original links, holding a spinning stud with the 5mm key. Assemble the sway-bar joint with a washer under the bolt head, the link, another washer, then the bar, flat washer, lock washer and nut. Grease bushing faces that contact washers.

STEP 02

Align at ride height

Use the corresponding illustrated stack at the control-arm end. Snug the hardware, lower to normal ride height and check that each link is close to vertical. Use the supplied additional washers to correct lateral offset rather than forcing the bushings sideways.

STEP 03

Torque and maintain

After alignment, torque the upper joints and then lower joints to 35–40 ft-lb. Check noises and hardware after the test drive. Future lubrication must use the specified Energy Suspension grease on sleeves and bushing faces.
