Tech Tip: Kia Front Suspension Noise on Bumpy Roads

Some owners of 2002-'05 Sedona vehicles produced from 5/1/2001-8/31/2005 may complain of front suspension noises over rough road surfaces at speeds between 18-31 mph.

Some owners of 2002-’05 Sedona vehicles produced from 5/1/2001-8/31/2005 may complain of front suspension noises over rough road surfaces at speeds between 18-31 mph. To reduce the noise, Kia has redesigned the strut mount with a modified rubber composition to improve the overall sound dampening in the affected speed range.

However, all other suspension components should be checked for performance prior to installing these replacement strut mounts. Concerns with worn out struts and/or rubber mounting components should be addressed before installing these revised mounts. Note: This TSB should be used for customer complaints only at speeds between 18-31 mph.

Note: Use date coding on the mount assembly to determine whether the mount is of the latest configuration (Note the three letters stamped on top of the mount). The days of the month run A-Z then 1, 2, 3, 4 and 5 due to the fact there are only 26 alpha letters available.

Service Procedure:
1. Raise and properly support the vehicle.

2. Remove the front tire and wheel assembly.

3. Remove the two lower strut-to-upper-steering-knuckle bolts on each side.

4. Disconnect the brake hose and ABS wheel speed sensor from the strut assembly.

Note: Note the orientation of the mount before removal from the vehicle.

5. Open the hood and remove the four upper strut retaining nuts.

6. Remove the strut assembly from the vehicle. Mount it into the strut compressor.

7. Compress the strut assembly using the manufacturer’s instructions provided with the tool and replace the upper strut mount assembly as required. Torque the strut-to-strut mount nut to 88-101 lbs.-ft. (120-137 Nm).

Note: Position the dimple to match the mount orientation as removed in Step 5.

8. Install the strut assembly into the vehicle. Tighten the four upper mount nuts to 33-46 lbs.-ft. (46-62 Nm).

9. Connect the brake hose and ABS speed sensor to their retaining bracket.

10. Install the two (2) lower strut-to-upper-steering-knuckle bolts and nuts; tighten to 65-79 lbs.-ft. (88-108 Nm).

11. Install the wheel and tire assembly. Tighten the lug nuts to 65-79 lbs.-ft. (88-108 Nm).

12. Repeat the procedure for the other side, if necessary.

13. Perform a wheel alignment.

Choosing the Right Power Steering Fluid

Learn what power steering fluid is, why it’s crucial for your customers vehicle, and how to choose the right type.

So what is power steering fluid? Power steering fluid is hydraulic oil for the most part, with certain additives that are tuned for the automotive applications, but it is hydraulic fluid. In other words, you have a pump that creates pressure and that force is changed into energy at a steering rack by turning the wheels or extending the tie rods in either direction. What else is hydraulic on the vehicle? The automatic transmission. This is why some vehicles will actually specify transmission fluid to be used inside the power steering system, but there are exceptions. Certain vehicles out there, mostly Asian, have their own formulation of power steering fluid. So it is absolutely critical that you match the power steering fluid with the application. Some may use a different weight of oil, and if you use the wrong power steering fluid, it can change the feel of the steering, but most of all, it can damage the pump and the rack on the vehicle.
