06 SL55 Clicking sound when Turning the steering wheel Backing out of the Driveway.
Hey guys,
Im experiencing a clicking sound as I'm turning the wheel to the car at low speeds when backing out of the driveway or pulling into a parking space. The sound is coming from close to the wheels, axel, control arm area..... Does anybody know what this might be from? I'm dying to know so I could get this fixed because the sound is quite annoying. Any help would be great. Thanks!

Front thrust arm and control arm bushings can crack and sometimes tear completely. If this is not repaired quickly, damage to the front subframe unit will occur, which is very expensive to repair. Updated control arms (that prevent damage to the subframe when the bushings wear out) are available.

Cracking Noise when Steering Left or Right
If you receive customer reports of cracking noise when steering left or right at low speeds just before limit
stops, noticeable also at steering wheel this may be caused by lost preload and settling or poor contact
surface between diagonal struts (Figure 1, 1) or the reinforcement plate (Figure 1, 2) and the front axle
carrier. The cracking movement is noticeable on the steering gear on a stationary vehicle with wheels on
the ground when steering to left or right. To resolve it is necessary to clean bolted contact surfaces
between diagonal struts, reinforcement plate and the front axle carrier.
Note: The steering rack is not the cause of the cracking noise. Do not replace steering rack!
Note: The below procedure must be performed on a drive-on lift. Vehicle must rest on wheels.
1. Remove lower engine compartment paneling. Refer to WIS document AR61.20-P-1105R.
2. Unclip cover on diagonal struts at front.
3. Remove diagonal struts (Figure 1, 1).
4. Check and clean thoroughly contact surfaces if necessary on the struts and on the front axle carrier
to ensure firm connection when attached.
5. Remove reinforcement plate (Figure 2, 2) from front axle carrier.
6. Check and clean contact surfaces if necessary on the plate and on the front axle carrier to ensure
firm connection when attached.
7. Install reinforcement plate (Figure 1, 2) on front axle carrier. Torque retaining bolts to 12 Nm. Refer
to BA62.30-P-1006-01A entry in WIS doc BA62.30-P-1000-01A.

clicking wheel
What type of wheel do you have? If it is a two piece AMG similar to standard wheels on a SL65 it is usually due to cracked wheel or loose wheel screws. I have had two wheels go south and both were due to defects in the wheel. They both clicked each time the affected area rolled on the ground.
