It means the rear trailing arm bushings are worn out and if that is the case the rear end won't track properly. The vehicle will appear to "dog" track.
It basically means that the rubber bush ( or "hinge) between a major suspension part and the body/frame of your vehicle has worn away or become damaged. This is normal as the vehicle gets older and should not be a big deal to fix. Because the part effects the way your vehicle handles on the highway, and it is part of the annual inspection, you need to get it fixed.
Trailing edge is the rear edge of a wing.
The trailing arms are what holds the rear end/axel on. The bushings are what allow movement of the arms.
Yes
Whenever they have failed.
trailing arm you mean? is common in front wheel drive cars it acts as a rear axle
My quote from volkswagen is £67.85 for anti roll bar bushes and £244.37 for rear axle bushes
check rubber bushes on ends of rear shocks or the main axle bushes - these can knock when driving if they are badly worn
When your rear trailing arm (rear control arm) are bad you will hear a clunking noise when going over bumps and potholes .... This noise is louder and more noticible while you have passengers in the rear seats..... You will also hear your tires squeek a little on turns
It is most definately dangerous.
The rear suspension Trailing Arm bushings are likely worn out and/or the rear shocks are in need of replacement. There is an upper and a lower trailing arm on both sides of the vehicle in the rear suspension. As a test, grab a firm hold on the lower trailing arm and try to twist it. If your able to move it even a little, the bushings are shot.
it is part of the trailing arm, not sold separately. part #15292403 right side, part # 15292404 left side.
