方向盘跑得厉害，要很用力hold住才能保持方向，这个正常吗？好像
FWD的没这么严重，轻轻用力就能保持方向。不知道是都这样，还是这辆车
有点问题。 |

发帖数: 6810 | 3 就是跟最近开的车camry, HHR, sentra, some small and mid size
cars比，很明显的不同。这些车过坑虽然也有方向盘转动，但大致能保持方向。
IS 250的如果不拉回来恨不得能change lane，转动很大的意思。

发帖数: 38 | 4 It depends on how bad it is. RWD cars' steering is more subject to
bumps due to no power on the front wheels, but it's really bad,
it's a problem. You need to check balljoints and lower control arms.
RWDs cards need stronger front suspension parts and tighter assembly
to absorb shocks. Some manufacturers don't honor this requirement.
Consequently, The front suspensions on their RWD models wear much faster
than those on their FWD models.
Lexus GS/IS from 1998-2004 is an example of such inexperienced (or
cheap) design. Not sure about their newer models.

发帖数: 38 | 6 Yes, BMW's front suspension is much better.
If IS is as you described, chances are it will have the same infamous front
suspension issue as its precedessor 60K miles down the road.

吧。
