发帖数: 24 | 1 3年新的bmw x3，才35000 miles，还在 warrenty内。星期五晚从高速上下来，在小路
上突然 没有了 steering control,还好速度不快，没有发生事故 。今天dealer看了车
，说是rod halfway cut导致要 replace rack and pinion, left front upper
control thrust arm with bushing,零件加人工，要4000。dealer说rod被人cut了一半
，所以不在warrenty范围内。我觉得挺冤的，我什么错也没有， 车也有warrenty竟然
要付这么多钱。而且听上去也很离奇，就是有人要害我，也不用去cut rod，还cut刚好
一半。dealer还说他们也不能确定这个cut是什么时候发生的。cut后车也能开，什么时
候出事都是随机的 。想问问大家，这种情况有没有什么argue的空间。多谢了！ |

发帖数: 2558 | 2 “Subaru’s top-of-the-line Outback H6-3.0 VDC also uses a planetary center
differential, which normally splits thrust 45/55 front to rear. But when the
“Vehicle Dynamics Control” stability system senses wheel slippage or an
impending slide, it instructs a hydraulic clutch on the center diff to
redistribute torque and then begins to apply braking and, if necessary, fuel
shutoff to regain control. Sadly, the VDC system can be neither canceled
nor cajoled into allowing even the least little bit of s... 阅读全帖 |

balancing做了两次了，会不会是需要装Hubcentric rings? 即使是原装的sport 17“

还是说rim本身有问题？
Alignment会引起这样的vibration不？
还有没有可能是thrust control arm？如果是那个，有没有啥问题不？不打算折腾如果
是这个issue的话 |

发帖数: 2128 | 11 I see. 谢谢3k哥
那如果我感觉车子低速有震动，就像是轮子不圆的感觉，是不是suspension哪里有问题
了？倒反速度上去了，就不明显。当然30-50左右steering有抖动（这个可能是thrust
arm bushing的问题，这个不管）。
1）车胎是新的
2）road force balance过了
3）由于是原装rim，估计没有wheel hub central ring的问题（当然我还没有拆开看看
，但是我估计应该是74.1mm的）
4）costco说我没有bent rim
我只是想知道，低速抖动是什么问题。如果不是很麻烦同时part也不贵，我很想折腾一
下。
本周末会将后轮往前轮rotate，如果是bent rim，按理说rotate后就能知道。 |

既然没有bent rim那就可以排除轮子的问题.找个靠谱的mechanic给你彻底检查下底盘
就知道哪里有问题了,在这里猜没啥用.很多时候一个问题是由好几个部件的松动造成的
,维修的时候要把不好的部件统统换掉,只换一个的话由于其他部件不好,会造成你新换

turbo lag. BMW’s motor has two different size turbos that kick in at
different phases of the rev range. What it means to the driver is nearly non

The new all-wheel-drive system is supplied by Magna and dispenses with the
lockable center differential employed in the Santa Fe’s predecessor. The
system can transfer as much as 46 percent of engine torque to the rear axle
using a servo-motor-operated clutch pack mounted ahead of the rear
differential. In normal operation, 97 percent of the engine’s thrust goes
to the front wheels.

manual transmission (TR6060-MM6) and a shorter final drive ratio (3.91:1)

从最开始的换灯泡开始，一路自己买工具，看教程，捉摸修，感觉很多设计还是为后期
的维护考虑的，只不过很多需要专用工具，Bolt Torque自己到TIS上查。换过Valve
Cover Gasket, CCV, Spark Plugs, Tensioner, Idler Pulley, V-Belt, A/C Belt,
Window Regulators (2X), Crankcase Positioning Sensor, Brake Pads & Rotors (
4X), Lower&Thrust Control Arms, Drive Axle, Struts & Shock Absorbers, HID
Conversion (w/ Projector).
暂时能想起来的就这么多。其他的像换油之类的就不赘述了，想必大家也都动手能力很

Considering that the diminutive Abarth comes with a roly-poly driving

on the market (honestly, it’s like a bowling pin), this is still a
ridiculously fun car to drive. Forward thrust is short of a Mini Cooper S
JCW or similar, but then, so’s the price point. However, where the little
Abarth really earns its name is in the startling rumble that comes out of
its twin exhausts when you fire it up.

stabilisation measures. The Dynamic Stability Control system curbs the

个关于proposal writing的疑惑，憋在心里struggle很久了，这次的review comments
里也反映了出来：当描述proposed research的时候，如果一个research thrust讲的很
细很清楚（比如好比写paper那样描述建模以及解法的idea），那么reviewer就会说你
proposed research is incremental，因为他看懂了，然后感觉根本问题已经基本上解
决了。如果讲的很high level，reviewer又会说idea not convincing and solid,
lack of insights, more details are needed, etc.

b) "f(int)" from A cannot be overridden because it is private in A.
Therefore, the code declares two new non-virtual functions.
This is incorrect. Whether a member function is private or not does not
play in determining whether or not it can be overridden.
d) "f(int)" is overridden and made public in B. "f(long)" does not hide it.
