Step 2:

Break free the lug nuts on the front of the Jeep (Do not completely loosen or remove the lugnuts!)

Place wheel chocks at the rear wheels of the vehicle.   Jack up the front of the Jeep as high as you can place the jack stands securely under the frame of the Jeep and under the axle. Now lower the jack. 

Step 3:  

Remove lug nuts and the front wheels to provide more working space .

Step 4:

Use a 21mm wrench and socket to remove the lower control arm completely

 (Take a photo reference of where your cam slot location is on the vehicle before removing you’ll need this later on  TJ3011 Only)

Step 5: 

With the lower control arm removed use a your cutting tool of choice to remove the lower control arm bracket off of the axle and grind the surface smooth with a angle grinder using a flap disk to ensure it is clean and ready for welding . 

Step 6:

Control arm Bracket  Orientation  TJ3011-1 & TJ3012-1 Will be on the Passenger side, TJ3011-2 & TJ3012-2 Will be for the Driver side .   

Step 7:

Place the Corresponding control arm bracket under the axle Rotate it up under the coil bucket the tab on the outside of the control arm bracket should make contact with the underside of the coil bucket.    Once that makes contact  measure 1/4" between the inside edge of the control arm bracket and outside of the coil bucket  Then weld into place.  

Step 8:  (TJ3011 Only )

Weld the TJ3011-3 Pieces (Cam adjustment plates)  on the control arms the control arm bracket will have a laser etched mark for placement.   

Step 9:

 Weld the seams where the sides and bottom of Lca mount meet the front corners (if looking from front of vehicle) can be left open to help Water and mud drain .

Step 10:

Paint brackets with a self-etching primer and paint (We find that rustolem gives the best results.)

Step 11:

Reinstall the Lower control arms ( We find it easier to slip axle end of the arm into bracket first then put the frame side into place.  Slip in the bolts and keep the nuts loose.

Step 12:

Install tires and lugnuts (Do not fully tighten lug nuts)

Step 13:

Use a Jack to raise the Jeep off of the Jack stands and remove them from under the vehicle then lower the Jack .

Step 14: 

Torque the Lug nuts to Manufacturer Spec. ( 95ftlbs)

Step 15:

Adjust Cam bolt so it matches the Photo reference you took earlier (TJ3011 only)

Step16:

Torque Lca bolts To 85ftlbs At axle end and 130ftlbs at the Frame  (Stock control Arms)

If you have Aftermarket  control arms refer to their manufacturers spec  Most aftermarket lowers control arm manufacturers suggest 90ftlbs for frame and axle end of link.

Step 17:  Take vehicle to have an alignment performed to ensure everything is in proper adjustment .
