Replying to: tidester (Sep 24, 2009 8:59 am) 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...?) |

Replying to: cotmc (Sep 24, 2009 11:38 am) 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?

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. |

"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. " http://www.insideline.com/bmw/x3/2005/long-term-test-2005-bmw-x3.html 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? |

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. tidester, host SUVs and Smart Shopper |
