SUBFRAME With Steering Gear, Removing And Installing: Removing
-- Before starting the procedure, measure the distance from the center of the wheel to the lower edge of the wheel housing. Refer to WHEEL BEARING IN CONTROL POSITION, LIFTING VEHICLES WITH AIR SUSPENSION or WHEEL BEARING IN CURB WEIGHT, LIFTING VEHICLES WITH COIL SPRING .
-- Place the vehicle on a hoist. Refer to RAISING AND LOWERING WITH OPEN AND CLOSED AIR SUSPENSION SYSTEM .
-- For vehicles with an air suspension system, bleed the air suspension system. Refer to SYSTEM, VENTING OR FILLING .
-- Remove the engine cover.
-- Support the engine completely using the :10-222A . Refer to ENGINE, SUPPORTING IN INSTALLED POSITION [For engine(s) CREC, REH] or ENGINE, SUPPORTING IN INSTALLED POSITION [For engine(s) CTGE, EUC] or ENGINE, SUPPORTING IN INSTALLED POSITION [For engine(s) CPNB] .
-- Remove the front wheels.
-- Remove the noise insulation -1 and 2-. Refer to NOISE INSULATION .
-- Remove the left and right front wheel housing liners. Refer to WHEEL HOUSING LINER .
-- Remove the nuts -3- and remove the cover -2- (if equipped) from the right and left drive axle.
-- Tip the top of the cover -2- toward the outside and guide it downward by the seam -1-.
-- Remove the left and right wheel spoiler. Refer to WHEEL HOUSING LINER .
-- Disconnect the left and right connector -1- from the vehicle level sensor (if equipped) and remove the clip -arrow-.
-- Remove the right and left clamps for the vehicle level sensor wires from the subframe.
-- Free up the electrical wire.
-- Remove the connector -1- for the vehicle signals (CAN bus and terminal 15) from the Power Steering Control Module -J500-.

-- Free up the clip -arrow-, disconnect the connector -1- and free up the electric wire.
-- If installed, remove the remaining clips -arrows- on the crossbrace and free up the wiring harness.
Ignore Items -1 through 5-.
-- If installed, open the clip -arrow- on the left rear subframe and free up the wiring harness.
-- Turn the steering wheel so that the wheels are in the straight-ahead position and then tape it secure -arrow- so that it cannot turn.
Be sure to use tape that will not leave behind any residue when it is removed.
Be careful not to turn the steering wheel during the repair because the Airbag Spiral Spring/Return Spring with Slip Ring -F138- can become damaged.
-- Remove the bolt -arrow-.
-- Remove the universal joint -1- from the steering gear -2- and support the steering intermediate shaft so that it cannot fall.
-- Remove the right and left nuts -1- and bolts -2- and remove the heat shield upper section -3-.
-- If equipped remove the Transmission Fluid Cooling Valve -N509-. Refer to COOLANT VALVES, REMOVING AND INSTALLING [For engine(s) CYNB] or COOLANT VALVE, REMOVING AND INSTALLING [For engine(s) CTGE, EUC] or COOLANT VALVE, REMOVING AND INSTALLING [For engine(s) CPNB] or COOLANT VALVE, REMOVING AND INSTALLING [For engine(s) CREC, REH] or COOLANT VALVES, REMOVING AND INSTALLING [For transmission(s) 0B5, CK] [For engine(s) CYNB] .
-- For vehicles with an intermediate flange -1-, remove the bolts -2 and 3- and free up the intermediate flange with the hoses still connected.
-- Tie up the left and right wheel bearing housings using the :T10083 -1-, as illustrated.
To prevent the joints on the upper control arm from being damaged, support the wheel bearing housing.
-- Remove the left and right control arms. Refer to CONTROL ARM, REMOVING AND INSTALLING .
-- Remove the nut from the left and right guide link joint pins enough so it is flush with the joint pin threads. Counterhold the joint pins if necessary.
-- Press the guide link joint pin off the conical seat using the :T40042 .
Be careful not to damage CV boot in the process!
Make sure that both puller lever arms are parallel to each other when using greatest force.
-- Separate the left and right guide link from the wheel bearing housing. Be careful not to damage the CV boot on the guide link joint pin.
-- Remove the threaded connector -1- for the right and left coupling rods on the shock absorber fork.
-- Disconnect and free up the connectors -1- for the Right Electrohydraulic Engine Mount Solenoid Valve -N145- and -2- and for the Left Electrohydraulic Engine Mount Solenoid Valve -N144-.
