Here's a video I recorded some time in 2005-ish with an old friend, Richie. I used a throwaway Logitech 4000 USB webcam, lots of duct tape (...like 2 yards), and a laptop. This video is almost a decade old, and depicts a failed suspension bushing under various loading conditions.
You are looking at a failed driver side Rear Trailing Arm Bushing (RTAB) of a 1998 BMW 323is (E36 chassis, stock GM automatic transmission [built in France]). The bottom of the video frame is the front of the car, the top is the rear. Notice how the trailing arm (the thing that's moving in the video) is able to wobble about as it mushes around inside the RTA console as the rear wheel undergoes loading forces. This is a perfect example of:
A) A failed RTA Bushing.
B) Why you should install RTAB limiters to prevent this kind of behavior, and double the life of your bushings.
When the Rear Trailing Arm (RTA) moves left to right, the rear toe for that wheel is changing. If both left and right bushings are torn, you get toe out under acceleration, toe in during hard braking, and unstable toe over bumps and rough terrain - resulting in an unstable feeling rear end. This is bad. My car was crab-walking all over the place because of this bushing. I was having the 'rear steering' effect. When the car is under hard acceleration, the arm is allowed to move towards the front of the car (down,in reference to the video frame). Under hard braking, the arm moves backwards (up in reference to the video frame). Up and down (in and out in reference to the video frame) and rotational motion occurs when the wheel travels up and down over bumps. The bushing is there to assist in the absorption of road vibrations and isolate the car body from the wheel to increase passenger comfort and reduce noise. It's NOT there to allow the suspension geometry and alignment to change on the fly (as mine is in the video)
What I did in the video: Accelerate from a standstill through 1st gear, into 2nd, and then cycled full on and full off of the throttle 4 times, then drove at about 55 mph on some country roads (see video statistics link for google maps location). I then swerved left and right about 7-8 times at the end of the video (with no traffic, within lane constraints), you can see how the arm reacts to slow suspension travel.
Dialog: talking about how awful the bushing is, then about how my passenger window seal is broken and you have to open the door so the window seals. I tried to repair it with rubber cement and it looked melted - and failed. We cross paths with a police officer, and we swear a lot. I've grown up since then and recognize that is in bad taste and reflects quite poorly upon my character. In retrospect I regret my choice of vernacular during that age period.
How To: Change BMW E46 Lower Control Arm Bushings in 10min
a quick video showing how to change the lower control arm bushings.
Vehicle is a 2001 BMW 325i wagon
Start to finish in real time, might take about 30 min in the driveway, but
a great DIY.
Symptom: A clunk noise when tapping brake pedal
Fix your front end!

BMW e46 Trailing arm removal
BMW e46 Trailing arm removal:
Here is my first video showing how to remove the trailing arm on a BMW e46.
I had the wheelbearing replaced by a friend, but the protector (backing)
plate was damaged - the mounting holes for the parkbrake shoe got flattened
by the press. I tried to get the (very specific) recess into place again,
fitted everything and the brakeshoes came off during the test drive :argh:
I temporarily removed the shoes and continued testing.
I am now awaiting the new plate to arrive and in the mean time removed the
trailing arm for fitment.
The shop can replace the wheel bearing with a sliding hammer, which is
propably less work and there is no need for wheel alinment.
I prefer to have everything checked again.

In this DIY and How-To video, we'll outline the procedure for properly
using the control arm bushing remover and installer tool for removing or
installing the front control arm bushings on BMW 3-series models from 1984
One of the most common sources for front-end vibrations on BMWs and MINIs
is worn front control arm bushings. If all other front-end suspension and
steering parts are verified to be in proper functioning condition, it is
likely that the control arm bushings have become soft and are allowing the
suspension control arms to oscillate, causing the vibrations that can be
felt through the chassis and the steering wheel.
Replacing the control arm bushings on the 3-series BMW models from 1984
through 2005 (E30, E36, E46), can be accomplished by most DIYers in just a
couple hours .... If we have the proper tools. In addition the a floor
jack, jack-stands and common metric tools ranging from 16mm through 19mm
(in most cases), we need the control arm bushing removal and installation
In this DIY we will show how to remove and replace the control arm bushings
on the BMW 3-series models as noted above, using the control arm bushing
replacement tool set. Note that we will be installing the pre-assembled
control arm bushing and mount bracket assemblies. This will allow us to
replace the bushings without access to a hydraulic press.
Control arm bushing removal and install tool:
Bentley repair manual; as applicable to BMW or MINI model:
½" drive socket set, to include; 16mm through 19mm sockets (depending on
model), ratchet and extensions.
24mm combination wrench
27mm combination wrench or ½" drive socket
Control arm bushings with mount brackets, as applicable to BMW or MINI
This general outline for 3-series control arm bushing replacement assumes
that the proper Bentley repair manual is at hand.
1) Lift and properly support the front of the vehicle, so that the front
wheels are off the ground.
2) Remove the wheel/tire assembly.
NOTE: Some models may require removal of splash panels or shields in order
to access the control arm bushing mount brackets.
3) Remove the rear control arm bushing mount bracket by removing the two
bolts securing the bracket to the vehicle. Note the position and overall
relationship of the bracket and how it is mounted to the uni-body frame
rail, for the future re-installation.
4) Use the control arm bushing removal/install tool to remove the bushing
and bracket assembly from the end of the control arm pin.
5) Press the new bushing/mount assembly onto the control arm, using the
bushing removal/install tool. Note that some urethane bushings may not
require a press for this operation. Note that rubber bushings require a
lubricant to allow them to be pressed onto the arm. BMW specifies a
special lube that dries after assembly .... we like to use Silicone spray,
diluted dish soap or hair spray as alternatives. Take note of any alignment
marks, as well as the proper orientation (left / right and front / back) of
the mount bracket. Most of the applications will install with the mounting
arm, on the mount bracket, being parallel and in-line (on the same plane)
with the forward end of the control arm.
6) Install the bolts for the bushing mount bracket and torque to specs
(see the proper Bentley manual).
7) Replace the splash shields and the wheels/tires and torque the lug bolts
to the proper torque spec. Lower the vehicle.
