Legacy F6-3.0L (2005)
Control Arm Bushing: Technical Service Bulletins
Suspension - Front Lower Control Arm Bushings
2005~06MY Legacy Front Lower Control Arm bushings
Dealers have reported, and in some cases replaced, the Front Lower Control Arms for cracked bushings. Generally, replacement is not necessary. Even
with cracks up to 15mm across the outside surface, and all the way through the bushing from one side to the other, the bushing performance is still 20
times the strength of specification.
This type of bushing works with compressed rubber and when the control arm travels through its full stroke it stretches a small portion of the bushing and
will exhibit a crack or split. This does not affect the performance of the bushing and will not continue to spread to the rest of the bushing. It does not
cause body vibrations, noises, or braking issues. A Service Bulletin will be released outlining the above information. See image to the right.
Note: B9 Tribeca models have a similar design Control Arm Bushing. However, the material and characteristics of the bushing material may be slightly
different. The issue of cracking and its affects are being reviewed at this time. We will update this information for this model in a future issue of Tech
TIPS.
