VY 03 Calais vibration at 20-40kms

Forget what I said to some extent, it shouldn't matter. You will have a centre mount that will keep the pinion angle ok anyway unless the car is lowered.

Ok cheers mate, yeah I don't think it's lowered at all

Here's the car

 

[djwatson93]

There has been a few cases over the years where people have had the TS out of balance.

Well I got VT sitting here maybe I can swap the TS over

 

[djwatson93]

So where the middle join is of the tail shaft
I can slide it back and forth 1-3mm is that normal play

Also here is a photo of the trans mount
Do you think the sagging could be causing this vibe?

 

[djwatson93]

So changed the Transmission moint, put the old one from my VT and the crossmember with it,
Vibration is 80-90% gone,

Now gonna do the engine mounts when they arrive to try get rid of this small vibration at idle

 

[djwatson93]

The vibration after changing the trans mount has came back
Was only a second hand mount so will trying a brand-new one,

Had the engine mounts changed, they where completed split both sides,
The vibration has lessened but still persists

I am lost of what it could be, going to check wheel bearings but I'm pretty sure their fine

Anyone got any more advice
Cheers guys

Jack front or rear ends up...spin the wheels by hand.

If they're chucking wobblies buckled rim or wheel bearing.

After you've hit a few potholes the factory alloy wheels don't look flash on a balancing machine lol

Yeah I had a wheel alignment done gotta go back in 700 more KMs to checks it's all good, but they said it was fine when they first did it

I'm starting to think maybe the tailshaft or even diff

Tis doing my head in I can tell you that haha

A little tip...Wheel alignments unless the settings are way out, don't cause vibration issues....

If a place says it does, they are trying to unnecessarily empty your wallet...

Oh and sorry the parts you have replaced are what I would have suggested as being the cause

Ok thanks mate,
Yeah I order the wheel alignment myself but year was to no avail,


I've noticed the centre bearing on the tailshaft has been replaced so I wonder if they put it in the wrong position

Im putting a exhaust on tomorrow hopefully so I'll have more of a look then see if I can see markers where it's meant to be aligned
