Owners of other Honda or Acura vehicles such as the Accord, Civic, Crosstour, CR-V, CR-Z, Fit, Insight, Odyssey, Pilot, Ridgeline, ILX, TSX, TLX, TL, RLX, RDX, NSX and MDX may also find these DIY instructions to be helpful.

The genuine OEM compatible replacement part numbers are as follows: Rear Coil Spring Honda 52441-S9V-A01, Rear Rubber Bump Stop Honda 52722-S9V-A04, Upper Insulator Honda 52686-S3V-023 and Rear Spring Seat Rubber Insulator Honda 52748-S0X-A00.

If you would like stronger coil springs, I recommend buying the Moog 81649 since they have a higher spring rate as well as being slightly taller and thicker than the OEM springs.

If you would like to also replace the shock absorber, the original OEM part number is Honda 52610-S9V-A02 or you could install some Monroe Load Adjusting Shock Absorbers.

The tools needed to complete this procedure include a lug nut wrench, a floor jack, two jack stands, a 10mm socket with a 1/4" drive ratchet, a 14mm wrench, a 5mm hex bit socket or a 5mm Allen key, a 17mm socket with a 3/8" drive ratchet, a 14mm deep well socket with an extension bar and a can of penetrating oil.

Engage the emergency / parking brake and place wheel chocks on both sides of the front tires to prevent the vehicle from moving.

Slightly loosen the five lug nuts on the rear wheel about 1/4 to 1/2 turn in the counterclockwise direction with the lug nut wrench.

Raise the rear of the SUV with the floor jack and securely support it with at least two jack stands.

Do not solely rely on the floor jack to support the vehicle!

Spin off the five lug nuts and set them aside in a safe place.

Pull off the rear wheel and set it aside.

Remove the 10mm bolts that hold the ABS sensor wire bracket to the control arm by turning them in the counterclockwise direction. Set the bolts aside in a safe place.

If you have trouble removing any of the bolts, spray on some penetrating oil and wait at least a few minutes.

Detach the lower half of the sway bar end link by loosening the fastener in the counterclockwise direction with the 5mm hex bit socket and a ratchet. While you are loosening the 5mm hex bolt, hold the nut in place with the 14mm wrench.

You may need to spray some penetrating oil on this bolt.

Do not fully remove the bolt!

Slightly raise the control arm to release the tension on the bolt that connects the control arm to the wheel hub.

Carefully pull out the bolt.

Pull out the old coil spring.

Loosen the fastener for the rubber bump stop in the counterclockwise direction with the 14mm deep well socket.

We found it easier to install the new coil spring first with the rubber bump stop loose inside the spring.

Make sure that the water drain holes in the insulator and the control arm are lined up.

Attach the new upper spring insulator to the top of the new coil spring.

Install the new coil spring.

Make sure the bottom "pig tail" end of the coil spring lines up with the drain hole in the rubber insulator and the control arm.

Tighten the new rubber bump stop in the clockwise direction with the deep well 14mm socket.

The rear bump stop bolt should be tightened to 29 lb-ft of torque as specified in the service manual.

Re-attach the sway bar stabilizer to the control arm. Tighten the fastener in the clockwise direction with the 5mm hex bit and a 14mm wrench to 36 lb-ft of torque.

(We also replaced the old shocks. Please check out my Monroe Load Adjusting Shock Installation Guide.)

Re-insert the bolt and tighten it in the clockwise direction with the 17mm socket and a ratchet.

If you have a torque wrench, the 17mm bolt torque service manual specification is 54 lb-ft.

Double check that all of the fasteners are tight.

Be sure to record the spring and bump stop replacement in your vehicle's service records.
