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 replace e36 trailing arm bushings without special tools (and installing POWERFLEX bushings)
Another diy video of me this time i am replacing one of my rtabs with
powerflex bushings. No special tools necessary although having an impact
wrench helps. Tools needed are: 10mm socket, 18mm socket, 17mm socket,
breaker bar, drill, 18mm wrench or 3/4 , hammer, flat head screw driver,
copper anti seize $1.50. Since you will be under the car, take necessary
precautions and wear eye protection when marking the bolt location. They
are dirty! I did not video myself hammering away but i did show the proper
way to hammer the bushing out. Enjoy and goodluck!
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.
BMW Control Arm Bushing Replacement
View this BMW Repair Tech Tip - follow this link:
This video explains how to replace front control arm bushings on your BMW
E30, E36, or E46 3-series that is experiencing control arm bushing failure.
The vehicle that these are being replaced on is an E46 330ci, but the
procedure is the same for the E30 and E36 3-series. This particular E46
had 62,000 Miles on it at the time of this replacement.
Integra Rear Suspension Rebuild: Rear Trailing Arm, Control Arms, Bushings, Sway Bar
As a complement to my earlier vid, here's a rebuild of the rear suspension
on my wife's old 1996 Acura Integra, hopefully you find it useful. It's a
bit long at 30 mins but covers removal of the rear trailing arm, lower
control arm, uppper control arm, and compensator arm. Then removal and
pressing out of the bushings on the rear trailing arm, lower control arm
and sway bar link, then reinstallation.
BEST of BMW M5 V10!! BURNOUT, DRIFTS, REVS!!
This video is a compilation of the best BMW M5 E60 V10 Exhaust sounds I have filmed in the last few
years. In this video you can hear the start up sound from the V10 engine,
some very loud revs, burnouts, drifts and mindblowing accelerations! Just
listen to the V10 engine sound, it's amazing! Maybe the best V10 ever made?
