I have just bought 2.2 CDX Auto 2003 Mot Jan 31st, Just serviced last week. I have noticed that the car is affected by unevenness/ruts/bumps in the road. It feels as if the wheels are loose (they are not).  Vauxhall dealer says tracking, tyres and two rear shocks should fix. Not likely, as Kwik fit says the tracking is ok, tyres are ok though not many miles left on them and didn't mention the shocks. The problem is very serious and unsafe. Can you advise, have you had this problem?

Shocks are easy enough to test by 'bouncing' that corner.

Jack up front, look for play in wishbones, track rod ends, and wheel bearings.

Also, consider getting a full geometry check done on it - tracking on an Omega is a waste of money imho.  See http://www.wheels-inmotion.co.uk for getting a full alignment done if you are near Chesham (South Buckinghamshire)

Shocks seem ok, the rest checked at MOT, but geometry test is a thought. Are there any parts in the steering box that may wear and cause such a problem?

Steering box is normally very reliable.

Just because something isn't picked up on MOT doesn't mean its not worth checking.  The bushes on the front wishbones are prone to failure after about 100k, so worth checking before spending to get fully aligned

Hi
The most likely culprit is the front tyres.  Omegas are very sensitive to front tyre design.  What size, make and model of tyre do you have.  I had Hancook on the front and it tramlined like crazy.  I changed to Pirelli P6 and now the car is stable and a pleasure to drive.

I have Pirelli P6 on all 4! have you heard  of tramlining as a result of worn rear shocks, I think the dealer is looking to make money rather than resolve my problem. Obviously I will replace the shocks if they are worn but according to MOT and Kwik Fit they are ok.

why is that Jaime, mine pulls to the left and i was going to have the tracking checked

my GLS pulled to the left even though the front wheel tracking was spot on, if you want to stop your car pulling to the left, get all 4 wheels aligned (full geometry setup), i took mine to A&M tyres at wigan, done digitally with the computer and those gadgets they stick on all 4 wheels, cost me about £42, there's also somewhere in oldham which i think was recommended by tony at Wheels In Motion as its obviously easier for us northerners to get to!

how much did that cost Danny

[chrisr]

I'd change the tyres if they're near to the limit, but as others and I have found steer (sorry!) clear of Pirelli P7s! The rear shocks can wait and they're easy to change yourself.

If the camber is to far out of adjustment then the car will try to correct that problem and the steering will suffer as a consiquence, so if you are happy that the front suspension bushes are all right than you need to get the geometry set up by Tony at WIM in hemel hempstead, he knows what an omega needs to make it drive as it should. Too many wheel tracking centres will put their equipment on the car and tell you that it is set up within spec, WELL IT AINT NO GOOD COS THE SPEC IS FOR A NEW CAR WITH NEW SPRINGS ETC, NOT A CAR WITH XXX MILES ON THE CLOCK. I can confirm that the pirreli p7's make for twitchy handling as i have them on my 2.5v6 but they are safe and handle ok after a trip to WIM. By the way where are you located?

Hi
As you are on P6's I would say the problem was probably wishbone bushes.  Worn rear shocks may have a very slight detrimental effect on tramlining, but it would be very slight, hardly noticeable.

Located Ayrshire, so those of you up north (oldham) are actually down south.

Hi there mate blimy thats a long way from  hemel, speak to brucie[hotel 21] he holds the record for a trip to WIM, But if you can get your camber set to about 1,10 for fronts then you may see a difference as this is the setting that tony gives as the best for the omega.
