,不会也是subframe吧? |
b**********g 发帖数: 534 | 2 It's clunk noise from the rear, put a smaller metal box in a bigger one and
shake, that's what it's like.
But that's only from my torn subframe, and it's also related to torn diff
bushings.
Your subframe can still be torn w/o significant noise.
The best you can do is visual check.
Support your diff with a jack and unbolt the 2 rear bolts, brush off all the
coatings and look at the metal.
I don't think subframe can cause much braking issue as subframe is in the
rear but most braking power is from

s*******e 发帖数: 3042 | 4 thanks. seems the jerk i have is not due to subframe tear. i checked
e46fanatics and bimmerforums, they all say never heard any xi having
subframe problem due to less torque at the rear wheels and stronger lower
body |
b**********g 发帖数: 534 | 5 most problems are found in early e46, mine was a 2000 model.
xi wasn't available untill after the facelift I believe, so you should be
fine. |

D*****I 发帖数: 8268 | 10 是啊,怀疑是differential bushing,
rtab已经换过了,subframe去查过也没问题
反正还能忍受。。
