默认 车子响,求教大虾。

最近发现,俺的7年jetta, 左前下方,车子行使时,吱吱作响。象是擦着金属的声音。
踩break时就不响了。开到100~120 也响。
以前右前下方响过,没管它,后来没事。
车刹的皮还好。

昨天还觉得,开到120时,车子好像没平时有力,提不起劲来,方向盘抖。
除此之外,没其他症状。

请教大虾,会是啥问题?

起来,不愿做奴隶的人们!

车子响可能是由于刹车盘的挡泥板摩擦刹车盘,用手推推试试.车无力可检查tune up项目和刹车系统(有可能是卡钳无法正常松开,通常还会伴随有一个或多个轮子异常发热).方向盘抖检查动平衡.

wow, 原来是三个不同的问题!那刹车盘的挡泥板可以推得动吗?

打开检查刹车。
半年前右轮子响 (低速时),打开看过没发现问题。 后来自己不响啦。
现在是前左轮子响 (高速时)。 今天下雨响得少, 没管它。 还差1千km就去换油,到时候打开看看。

还是感觉开120时,方向盘颤得厉害, 140km时反而好点。 100以下没问题。
早天油便宜,加满87级的,不知这是不是车子没力气的关系(以前都是用89/91的)。

谢谢各位大虾!

解决了个半问题。车子有劲了, 前左轮响少啦。

原因是车胎没气, 才1.8psi. 外表竞然看不出瘪。车子停着不开,气却比开时逃得快。

120km时,方向盘仍颤。
