Honda Tech Tip: New Bolts Silence Clunky CR-V

A Honda CR-V driver may complain of a clunking noise from the front suspension when driving over bumps. The probable cause is that the upper arm flange bolts do not properly clamp the upper arm bushings. To correct the condition, replace the upper arm flange bolts as described in this Tech Tip.

Applicable Models:
1997-’99 CR-V, up to VIN JHLRD_XC_figure 1

Parts Information:
Flange Bolt, 10 x 68 mm (4 required): P/N 90172-S04-003 

Repair Procedure:
1. Record your customer’s radio station presets.

2. Disconnect and remove the battery (see Fig. 1). 

3. Raise the vehicle on a hoist, just enough to lift the wheels off the ground.

4. Remove the air cleaner housing (see Fig. 1). 

5. Loosen the two flange bolts from the right upper arm. Repeat this step on the left side (see Fig. 1).

6. While supporting the right front tire with your hand, remove the flange bolts, and ease the upper arm away from the upper arm mount. Discard the flange bolts. Repeat this step on the left side (see Fig. 2).  figure 2

7. Raise the vehicle about four feet off the ground. figure 3

8. From inside the right front wheel well, look for traces of body sealer in the upper arm mounting areas. If any body sealer is found, remove it with a gasket scraper. Repeat this step on the left side (see Fig. 3).
Note: Be careful not to scratch the body finish. If you do, repair the area with touch-up paint. 

9. Lower the vehicle until the wheels are just off the ground. Figure 4

10. Reinstall the right upper arm, and secure it with two new flange bolts (see Parts Information). Repeat this step on the left side (see Fig. 4). 

Note: When installing the new flange bolts, you may need to move the tire slightly with your hand to align the bolt holes.

11. Lower the vehicle to the ground, and then  torque the four new flange bolts to 54 lb.-ft. (73 Nm).

12. Reinstall the air cleaner housing. Torque the two flange bolts to 7.2 lb.-ft. (9.8 Nm).

13. Reinstall the battery.

14. Reset the radio station presets, and set the clock.

15. Test-drive the vehicle over bumps to make sure the noise is gone.

It is critical to remember that toe is not always zero or straight ahead.

Toe is the most critical alignment angle. It is also an angle that can change as the weight of the vehicle is transferred to the front or rear wheels. Engineers can tune the suspension geometry and toe to make the vehicle more stable under braking or initial turn in.
