Hi,

Like to find out a little bit more on the Tail Shaft Coupling? Where is it located & what it look like? Is it expensive to change?


Kind Regards

Is it a rubber component?

there is one at each end of the shaft. Looks like a rubber donut with 6 holes.

The transmission end is prone to breakdown after a few years and should be replaced when it shows sign of deterioration.

The differential end typically lasts longer.

The part is around $75, labor of about 1 - 2 hr. depending on which end.

Check out the pictures at Fastlane.

Thanks

What'll happend if this part is not replace, coz I dont notice any difference at this stage? Should all the rubber parts be replaced, done at once?


Kind Regards

Depends on age and wear of the disks. Inspection is best to make the decision.

If the original disks and over 10+ years, consideration to replace should be given as for all old rubber components.

The front flex is subject to greater heat and flex than the rear so is more likely to fail.

The consensus seems to be that the disks can be replaced independently unless you are going to remove the entire tail shaft to renew the support bearing in which case both disks should be replaced to save labor.

Yes my car is now 11 yrs old, the shop just rang me said only replace fron end, he said back end is fine?

Is this OK for AU$330 work?

Whats the effect of not replacing this part? Is there a noise in transmission or...?

Kind Regards

I converted that to ~US$250 which sounds fair to me since it likely involves putting the car on a lift, possibly removing parts of the exhaust shield and removing/replacing the disk while supporting the transmission. The part alone could be AUD$100.

The rear disk is often just fine even when the front needs replacement.

If the disk disintegrates while running at high speed, the driveline could flop around and cause damage to the shaft tunnel which I understand also is near air-bag collision sensors which might deploy the bags.

I have now test drive the car, since yesterday when I accelerate there seem to be a minute vibration coming from the front. Is this because of the new mount or the tailshaft coupling.

The vibration sounds/feel like from the left/passenger side of the wheel or engine? I notice when I see the car being work on, the mechanic was working on the left side near the wheel section, is this where the tailshaft located or the mount??

If you replaced the front flex coupling, there should be no vibration coming from the side since the drive shaft is on the car centerline.

It sounds like an unrelated problem, maybe a worn wheel bearing or suspension component?
