i have a 02 omega sport 2.2 had it for a couple of years. I suffer on our crap  roads of the car suddenly wandering around with the contours of the road surface .

You have to be careful somtimes takes you by suprise
ok on larger roads and motorways 

any ideas  thanks very much

[Jimbob]

Could just be tyre wear or inflation
could be wishbone bushes
could be the steering idler.

all common causes of tramlining 

[christof]

thanks the tyres are brand new and have been aligned    would the sterring and wishbones be mot failures as it just saled thru for the third time in a row

bit odd really but concerning

[Jimbob]

Did it start with the new tyres?

was it just aligned, or full geometry?

the wishbones / idler  may / should fail MOT, but not always...

What is the condition of the shocks?
Surprisingly mine had the same problem and turned out that the biggest reason was lousy shocks (they stopped working completely so every small hole was the reason for sudden wandering around).

[christof]

did it b4 the new tyres

shocks passed the mot ok but car has done 126000 miles so it might be them

The problem with the MOT is that they can see any wear in the wishbones and their bushes but the steering drop arm idler cannot be easily seen or felt for wear to its internal bush.
This happened to me on my last test and when I changed the drop arm idler for a genuine Vx one the tramlining stopped.
If you have had new tyres and they are correctly fitted and inflated and the wishbones past the MOT then it only leaves one suspect. Its worth the cost to get it from VX and takesa DIY 20 mins to fit.

On mine, I have changed the shocks, links wishbone bushes, tyres and idler. The single most biggest difference was from changing the idler arm. There is a bit of tramlining still present but its nowhere as bad as before.

Have you investgated the track rod ends?

If you're unsure about the idler, take the passenger side wheel off and give the disc a good yank side to side at 3 and 9 o clock. If the idler has gone you will see the assembly and idler all move.

I first had this a few months ago and assumed tyre pressures or some other fault and had the steering carefully examined with no result.
 I have now discovered that this only happens on one particular stretch of tarmac a few hundred yards long, regrettably it's near my house so I use it a lot. The lane doesn't look different but clearly it's been damaged by heavy vehicles. The issue doesn't affect our other cars so it's seems related to the wheel track and possibly the fatter tyres on the 2.5 .

It could just be the road at fault in which case all you can do is make a note of the dodgy bits and try to adapt. It still irritates me though.

I have a similar problem. I intend to check the steering idler first then change if found to be faulty.
See how I go with that before delving further into the problem.
Just waiting for the weather to get better now, too bl**dy cold to be faffing with cars, brrrrr
