Here you can find information regarding the assembly of the CX-9 front end. In this guide we will cover the
essential repairs for the front end of this vehicle. Included within these repairs
is the inner and outer tie rod removal and change, the front wheel hubs installation, ball joint removal and
installation, the upper and lower control arms, and the front shock installation. Along
with the repair procedures we also include the corresponding bolt torque specs for each fastener involved. These
guides are intended to assist in each procedure to help diyers with the job.
CX-9 Tie Rod Change/Removal
To install a new tie rod on a CX-9 you must first remove the old one from the vehicle. This can be
done by raising the vehicle up by either the use of a floor jack or a vehicle hoist.
Once the vehicle is in the air you can remove the corresponding tire for the side that you want to change the
tie rod on. Once the tire is off you can now access the old tie rod and remove it for replacement.
The outer part of the tie rod uses a nut that will need to be removed, this nut may spin with the rest of the tie rod depending on how
rusty it is. I suggest using a pair of vice grips to hold the portion of the bolt to prevent it from
spinning. You may also use a wire brush to clean off the threads prior to removal and or use penatrating oil to
aid in removal of the nut. Once removed you can now tap out the tie rod from the spindle and
start to remove it completely. If you want to replace just the outer portion of the tie rod you can remove the clamp bolts further down the tie rod and remove the outer portion of the rod and replace.
Once the outer tie rod is off you can now install the new part and reinstall it the same way it had been
removed. Once you get the nut back in place you can torque it to 40 ft-lbs. If doing the inner tie rod be sure to tighten it back up to 66 ft-lbs.

CX-9 Inner Tie Rod Torque Spec : 66 ft-lbs
CX-9 Tie Rod Locking Nuts Torque Spec : 20 ft-lbs
Front Wheel Hub Installation
To install the new wheel hub you must first remove the old hub from the vehicle. To do this you must first remove
the center axle nut from the vehicle. This is best done while the tire is still on the ground to prevent the entire assembly from
moving during removal. Next you will need to jack the vehicle up and remove the lugnuts and tire from the car.
Once the tire is off you will need to remove the bolts from the brake bracket on the steering
knuckle. These bolts will be rather tight so you may want to use an impact or find some
leverage. Once removed you can move the brake assembly out of the way and move the brake rotor from the vehicle.
Next you will have to remove the 4 bolts located behind the wheel hub that are used to hold the hub onto the knuckle.
With these 4 bolts removed you can take the hub off the vehicle. it may be somewhat difficult to pull the hub of as typically
it becomes stuck from corrosion and rust. I advise using some penetration fluid and a hammer to aid in this step. Once you
get the hub off the car you can clean up the hole which it was in and place the new hub onto the steering knuckle and begin tightening
the 4 bolts that hold it. These bolts will need to be tightened down to 25 ft-lbs and then an additional 60 degree turn. Once all
have been installed and tightened you can begin to assemble the braking system back onto the car. The brake bracket should be tightened down
to 75 ft-lbs. The center axle nut will need to be tightened down to 180 ft-lbs.
The CX-9 has one set of front ball joints being the lower ball joints. The lower ball joint is apart of the
lower control arm but can be pressed out and changed to a new one using a pressing tool. In order to get room to press the old
ball joint out you simply need to remove the pinch bolt which holds the joint to the steering knuckle and then remove the tie rod end and
move the steering knuckle out of the way of the old ball joint. Then you can press it out and press the new one in. Once the new on is in you
can reconnect the tie rod and reinstall the ball joint into the pinch on the knuckle and tighten the pinch bolt to 30 ft-lbs.

Front Strut Installation
To replace the front struts on a CX-9 you will first need to remove the upper strut nuts which can be accessed from under the hood. There are 3
nuts which should not be that tight. With those removed we can now move to the side of the vehicle and remove the tire out of the way. There are
2 bolts which hold the bottom of the strut to the steering knuckle and then a bolt that holds the stabilizer link the the strut as well. These will need to be
removed before the strut can be taken out of the car. Once you have the old strut out you can place the new strut in and start installing it in the reverse
order of removal. Starting with the upper nuts we will hand tighten them and then move to the lower bolts and hand tighten them. With everything hand tightened we
can torque down the upper nuts to 40 ft-lbs and then the lower bolts to 170 ft-lbs. All that is left at this point is to tighten back up the stabilizer link to 35 ft-lbs
and then put the tire back on.

CX-9 Strut Lower Bolts Torque Spec : 170 ft-lbs
Control Arm Installation
The CX-9 front suspension uses a lower control arm and upper strut to hold the vehicles steering knuckle to the frame, The lower control arm consists of
bushings and the lower ball joint which is where it connects to the knuckle. To install a new control arm you can remove the tire from the car and then move to the
bottom of the knuckle and loosen up the pinch bolt which holds the ball joint to the knuckle. With the bolt removed the lower arm can be dislodged from the knuckle.
Next you can loosen up the inner control arm bolts which connects it to the cars frame. There is a total of 3 fasteners that connect the arm to the vehicles frame.
All 3 will need to be completely removed in order to replace the control arm. With all 3 fasteners removed you can remove the old arm and install the
new arm into the car. The left side control arm frame fastener gets tightened down to 175 ft-lbs. The right side fasteners can both be tightened down to
120 ft-lbs. With the frame fasteners installed and tightened you can push the ball joint into the steering knuckle and tighten down the pinch bolt to 30 ft-lbs.

Stabilizer Bar Installation
The CX-9 has a stabilizer bar in the front end that helps with the control and handling of the vehicle. This
bar conects to two ends of the vehicle via nuts and then has 2 brackets one being on each side of the vehicle to hold the bar into place.
The bracket bolts torque down to 20 ft-lbs while the endlinks tighten to 35 ft-lbs.
