That reminds me... I'm also trying to find a part number for the johnson rod. George Costanza mentioned this in one excellent auto dealer-related episode of Seinfeld. I think that's the same episode where the sales guy tries to add a "key charge" into Jerry's car purchase. (The salesman's explanation for this "key charge" was something like... "Without the key, how you gonna start your car??".)
 
I think our closest BMW dealer here likes to add up ALL these types of incidental charges into one $488 Documentation Fee. Otherwise, if $488 REALLY goes toward handling the documentation, then I would sign up for THAT job in heartbeat!! (Notice my feeble attempt to get this post back on topic...?)

Virbating or vibrating is on topic.
 
Pitching, swaying, rocking, rolling, bouncing, undulation, virbating and vibrating. Does anyone know how someone goes about softening a suspension without rebuilding a car from the bottom up?

Different tires ... taller sidewall?

Damping system? by pp2009pp
Oct 06, 2009 (6:03 pm)
As far as I understand this:
 
Sporty suspension = tightly sprung
 
The wheels stay in good contact with the road and lack of springingness means that where the wheels go the car's cabin goes. If a wheel goes down into a pothole, the cabin goes down into the pothole instead.
 
Bounciness/undulation/bucking = insufficient damping or dampening
 
When the springs begin to bounce from an imperfection in the road, the dampening structures including the shock absorbers are failing to dissipate the energy in the springs causing the car to continue to bounce. If the shocks are worn, I should be able to pull on the roof rails of the car, get it to rock and it should continue rocking.
 
Someone said to push on the door panels but I think pulling the roof rail (gently) accomplishes the same purpose...or not. I don't know.
 
Has anyone had early dampening or damping problems on their X3 and did replacing any components help?

It isn't potholes or large imperfections that causes the bounciness, it is small ones.

Someone on another forum is looking for taller tires to deal with the rough drive of the X3. I hope they will let people know if that works for them.
 
According to the dealer all of the ride issues (noise, bounciness, roughness, etc.) are due to the AWD. Who knew?
 
Whack forehead.

From Edmunds long term test by pp2009pp
Nov 05, 2009 (11:19 am)
"Problem History:
 
       1. Rear shocks blown on state-maintained fire access road. Shocks were replaced under warranty.
       2. Vehicle was rear-ended in traffic accident.
 
Dealer Service Reviews
Santa Monica BMW, Santa Monica, California
June 2005
 
An afternoon of cruising a bumpy desert road proved to be too much for the X3's rear suspension. Perhaps our test vehicle's street-focused sport package had something to do with it, but we're still left scratching our heads. In any case, both rear shocks were rendered useless, and several suspension parts needed replacement.
 
Though the bouncy ride back to the office was fun for a few miles, we ended up parking the X3 while we waited a week for the back-ordered parts to arrive. Santa Monica BMW handled the repairs with skill and efficiency, despite the delay on parts. "

Is this even remotely normal for an SUV/SAV - even one obviously not meant to do serious off roading - to do in just a single afternoon on a fire trail? Is this in any way related to the bouncy, bumpy ride or is it just an aberration in this particular car?

Getting worse? by pp2009pp
Nov 14, 2009 (6:40 pm)
A whole afternoon spent being jostled and bounced all over the place. It may be getting worse.
 
That would make sense if something is off in the suspension. It is EXHAUSTING.

It's clear this discussion is going nowhere and there is little interest in it so I'm turning it off at least for the time being.
