Hi everyone,Today im very happy because my 3 months old problem already settle. Just change whole long shaft from chop shop and vibration and berdengung sound gone. Before this i check the tires, dented rim if have, replace coupling (guibo), centre bush, T-coupling but cannot solve. My car checked at Bomin Auto Jalan Ipoh but they just said tyre balancing. Do tires balancing but still same. Go to one workshop at Bentong and mech suggest to change whole shaft. Mech also said if T-coupling jammed, no need to change it because original coupling from factory already centralize and balanced. If tukar jugak, machine shop will ketuk that T and its become senget. BTW, the long shaft from chop shop is from e46 320i. My car is 318i 2.0 but can use. The price is RM 1000 and labour cost is RM60 to cabut and pasang exhaust and whole shaft. It is reasonable price?TQ
