To fit ARB lockers, you need to drill and tap the Diff housing for the air supply for locker activation.

Step 1: Make a punch mark where you want to drill


Step 2: Drill a pilot hole with a small drill bit +- 3mm


Step 3: Drill the final hole to the size indicated in installation manual


Step 4: Insert the correct size tap, and lubricate with light oil or cutting fluid


Step 5: Rotate the tap to cut the thread to desired depth


Step 6: Clean the area thoroughly


Step 7: Test fit brass fitting

JT

recommendation;-

Put some silicon sealer or PTFE tape on the thread - it will help to prevent diff oil seepage over the long term.

Or something like Hermitite Red - non hardening gasket sealer?? Thanks JT, steady hands required to ensure hole is "straight" in when drilling or is this not mission critical? :-\
