[I_want_an_Omega]

Ok,

This is going to take a bit of explaining, so here is a bit of background  :-/

I've had a number of Omegas in the past - firstly as new company cars from '94 upto '01. Then a couple of years of private ownership to '03 and more recently from '09 to date.

All bar one of the company cars were replaced after just a few months use   (Vauxhall Fleet). I then took a '99 2.5 Elite from new to 60k and then bought a '98 MV6 which I took from 50k to 95k.

I returned to Omega ownership in '09 with a '98 2.5 CD estate which I chopped in for a '99 3.0 Elite which I still have.

That's the background - now for the problem .....

Without exception, all of the cars with higher miles (say above 50k) have suffered with the same problem. Steering vibration verging on wobble at anything above about 40mph.

Ok, on the basis that this has affected 4 vehicles over a period of perhaps 10 years I can't just be imagining it can I? Its not balancing/tracking as I've had all that on them all. Why didn't the lower mile cars do it?

It's an annoying niggle really.

Does anyone else have the same problem?

Could there be wear somewhere, if so "where"?

So, that's it. Don't know what to do next, can it be fixed, or is it just me? I'd like to get it fixed if possible.

Please discuss ..........

Mine doesn't & there's more than 3 times that mileage on my car.  :-/ :-/

runout on front discs?
wheel balancing?
wishbone bushes?

[henryd]

Wishbone bushes fubar most likely.

Either all checked on the older previous cars or recently replaced on current one. 

[Terbs]

98k on mine and never has had a wobble.

[I_want_an_Omega]

Wishbone bushes fubar most likely.

Replaced less than 2k ago with Lemforders. Am a bit reluctant to change them on a whim. How much work to Polybush them?

I've owned three Omega's. A 3.2 plod estate.......a 2.6 CD.......and a 2.6 MV6. I'm pleased to say I've never encountered this particular problem.


All have covered well in excess of 50,000 miles.

Who did the geometry when the wishbones were replaced?

[Andy H]

I am convinced that front brakedisks are the cause (either caused by poor manufacture or uneven wear in use).

Soggy bushes or wear in the suspension and steering exacerbate the problem.

Each time I fitted new disks to my last Omega the problem disappeared but slowly returned as the miles racked up again. Better quality disks seemed to last longer than cheaper ones.

I fitted new disks to this Omega about 25k ago and the vibration is starting to reappear again

[Lazydocker]

Steering idler?

Incidentally, it's not been an issue of either of mine

[Lazydocker]

Tbh, 25k from a set of discs is good if they're used heavily, especially if they are pattern parts

So, you have the same/similar issue?

The discs are Vx trade club ones.

Who did the geometry when the wishbones were replaced?

Only had the tracking done (National Tyres) on the current car, but had a full alignment done by WIM in Chesham on the previous one.

Am getting the front shocks/springs changed at the end of the week so will have everything up front checked over whilst she is up in the air.

[Marks DTM Calib]

I would still go for wheel balance.

I find that because of how wide the Omega wheels are that most places struggle to do a good balancing job on them.

Given its happening when driving without braking I would so its got to be a rotating item (and hence why wishbone bushes, pads etc is unlikely).

[I_want_an_Omega]

Only had them done a week ago
