READ ALL INSTRUCTIONS BEFORE STARTING INSTALLATION 

Step 1: 

Remove the emergency brake cable and thread it out of the stock control arm 



Step 2: 

Use a Jack stand to support the axle and disable movement (NOTE: only remove and install one LCA at a time to allow less axle movement and easier installation) 


Step 3: Remove the rear LCA bolt using the 1/2in ratchet and the 18mm socket (Note: the inside nut has its own stop and will stay in place.) 



Step 4: 

Remove the front LCA bolt using the 1/2 in ratchet and 18mm socket. This time the bolt will be towards the outside of the car, and the fixed nut will be towards the inside or midline. 


Step 5: 

Install the front end of the new control arm. Use the ratchet to get the control arm snug. (Note: The wide end of the control arm will be in the back while the skinnier portion will fit into place in the front.) 

Step 6: 

Install the rear end of the control arm into place and get the bolt snug. 


Step 7: 

Torque both the front and the back bolts to 130 ft pounds using a torque wrench. 

Step 8: 

Run the emergency brake cable under the control arm and fit the cable back into place using the retainer 

Step 9: 

Use a ziptie to hold the brake cable to lower control arm. 


Step 10: 

Follow these instructions for the other side. Keep in mind to only do one side at a time, and to disable axle movement by putting a jack stand under both sides of the axle.
