vibration during gear shift.

[clockwork]

Hi all ZTH bros,

i can feel the vibration when the RPM above 4000...GB going to kong????

 

[DanzEterna]

vibration where? in the engine compartment?
suspect drive shaft or engine mounting.....or clutch slip.

 

[clockwork]

feel it like from the engine bro....

 

[DanzEterna]

does it vibrate during pickup from 0-60km/h?
or also vibrate during idling?

 

[clockwork]

idling so far ok even at expressway on 5th gear when want to increase speed can feel the vibration....

 

[xtremeleo]

does it only vibrate above 4000rpm? is it speed related?

 

[clockwork]

even on low 3000rpm when want to increse also feel the same....

 

[DanzEterna]

suspect gearbox mounting or driveshaft.

 

[MKMD428]

yes. suspected DS causing the issue. or might as well your CV joint.

 

[clockwork]

ok thanks all bros i will ask my mech to check....confirm nothing to do with the airflow or tuning right?

mayber your inner cv joint(gearbox side),normally happen during acceleration/tekan minyak,if outer cv joint happen during take corner(ktak ktak).
driveshaft consist of, inner cv(gearbox side) -- driveshaft -- outer cv(tyre side)
get recon one or check for grease or tolerance inside the cv joint.

manual?auto?gearbox,racing clutch also vibrate a bit or when clutch slipped.experience before.

how to check the inner cv joint bro?
what u say is correct during acceleration/tekan minyak happen but when take corner no problem.is a manual gearbox bro with Exedy japan semi Clutch.

 

[sarutobi84]

if exedy 3 puck or 4 puck +heavy duty clutch the vibration only when release clutch.

in your case when tekan minyak or accelerate the most probabble is your inner cv.

how to check?no other choice other than have to dismantle the drive shaft and check for free play in the inner cv joint or no grease at all,try to rotate the cv joint when you pull the driveshaft out.most mechanic know how to check.check the cv cover as well.

based on experience,usually the knackered cv joint is on the reverse side of the vibration.let's say you experience vibration at left,the right one is the problematic one,sometimes can be both.

the easiest way is to get recon cv joint,and the knakered one send for recon and keep as spare parts.
