We can cross bearing and axle oil off the list then. Does the humming happen only when you are moving? try checking your long shaft, rear shaft, tires.

The noise come when you drive over 80km/h..forgot to mention that i've also change the center bearing for the longshaft..the tyre also new michelit ps3...and also change axle mounting...

could be the tires...try swapping them with the front ones. Eliminate the most easier and FOC part first...

I think it's the same noise...if not mistaken, the center bearing for my longshaft and guibo/rubber thinggy have been replaced..i think i've covererd almost 80% of posibilities except for drive shaft and longshaft...senang cerita saya dah hantar mekanik dan kebetulan dia ada simpan satu axle dengan longshaft so boleh try and error..sempat try axle saja sbb longshaft tak sama jenis...dah tukar axle masih tak hilang bunyi so dia ganti axle lama balik..tinggal longshaft saja saya tak try lagi..ada sapa-sapa sini yang tau kedai boleh testing dulu tanpa perlu terus kena beli longshaft?

 

[-fm-]

hi..., have you checked the subframe rubber mounts?

 

[eujinee]

kerana...saya tukar long shaft itu.....bunyi itu hilang.....try tengok...
