IMPORTANT :
BEFORE ATTEMPTING TO DISMANTLE YOUR VEHICLE FOR THIS
INSTALLATION, PLEASE READ THIS INSTALLATION GUIDE IN ITS
ENTIRETY, AS WELL AS ALL APPLICABLE SECTIONS OF YOUR
VEHICLE MANUFACTURER’S SERVICE MANUAL.
1.1
Pre-Installation Preparation
This booklet is to be used in conjunction with your vehicle 
manufacturer’s service manual. ARB endeavors to account for every 
possible variation in vehicle model when publishing its installation 
guides, and guides are updated regularly as new model information 
becomes available, however, the rapid and globally varied release of 
some vehicles makes it difficult to insure that your vehicle model has 
been accurately accounted for. In the case of any technical 
discrepancies between this guide and your service manual, we 
strongly advise that you adhere to the specifications and techniques 
as documented in your service manual. 
 
Although your ARB Air Locker comes complete with all the step by 
step instructions you will need to supplement your vehicle 
manufacturer’s service manual and install your new differential, ARB 
recommends that you have your Air Locker installed by a trained 
professional. Many ARB distributors around the world have been fully 
instructed in Air Locker installations by ARB, and have gained a wealth 
of experience and skill from years of performing similar installations. 
 
Once you begin this installation your vehicle will be immobile until all 
steps of the installation are complete. Make sure your Air Locker kit is 
the correct model for your vehicle and that it contains all of the parts 
listed on back cover of this booklet. Also be sure you have 
appropriately equipped yourself with all the necessary tools, parts, and 
materials to complete this installation (see Section 1.2 Tool-Kit 
Recommendations), and that you have allowed for an appropriate 
amount of vehicle down time. 
 
HINT :
Place a
mark inside each of the
symbols as
you complete each step. It is very important NOT to 
miss any of the steps!
