Omega rear end stability
15. Jan 2007 at 10:41

Hi all
My omega feels very twitchy at the rear. I live in Scotland, where the roads are often wet and winding. A few times in wet conditions the back end has tried to get away from the rest of the car. There is no excessive speed or steering involved. Tyre pressure and tread are all ok all round. It just feels vunerable on bends and roundabouts, mainly in the wet.

I remember about a year ago i was behind an omega that rounded a corner and I watched it fishtail in the same manner. Admittely this person did seem to be taking it a bit quick.

Just wondered if this is a common symptom or if there could be something mechanical causing this.

Would appreciate any comments.

Howdoo matey, just 30 miles south of you.

First check for me would be tyre pressures then make of tyres, before getting into the world of bushes, suspension, alignment etc. And a lot is on the way that a car is driven.

A lot of bigger cars can be fussy as to tyre make, and not always dearest is best. I had 4 Dunlops on my MV6 and there were not worth a button in the wet. Fitted F1's (costly.... ) but its like driving a different car.

I had a budget brand, cant remember the make, on a Carlton GSi and they were really quite good in both the dry and the wet.

Theres a meet of the Jockular Omegas (see thread in meetings on the home page http://www.omegaowners.com/forum/YaBB.pl?num=1166112170 ; ) at Callander next weekend. Might be worth dropping along for a chat and a swap of experiences?

I have only managed to get the back end sliding a couple of times but the TC manages to bring it back under control before I can enjoy it, even in the snow.

I had this happening too often for my liking when I first got my MV6. Largely due to the slick tyres, I think Shocked

- it hasn't happened since I replaced them (budget brand - but not cheap!), and I'm starting to gain a bit more confidence in cornering again. But I also think it has a lot to do with the automatic transmission (which I wasn't used to). It seems to change gear when I wouldn't normally choose to do so in a manual - such as half-way through a corner! I'm now a bit more careful about when I put on the power - try to make sure the wheels are in a straight line first!

Baz.

@BazMV6 - welcome to the fun of driving a powerfull rear drive atobox through bends... Wink

The other way to reduce the likelyhood (or increase it, if thats what you want) is to use the autobox like a manual via the 1st/2nd/3rd gear hold. That way you are basically driving the car like a manual but without the clutch and reducing or removing the involuntary gearchange timings.

Hi
Mileage is 88000 rear shocks not changed to my knowledge. The car is manual also. I think it is probably down to tyre brand. It has Bfgoodrich profilers. Not my choice, came with the car. Think I may just change them all before MOT in March.
Thanks to all for your replies and to Hotel21 for the invite to the Jockular Omegas meet. I shall try to make that, but depends on kids' weekend activities Tongue

MY REAR TYRES

Thanks again everyone Thumbs Up!

Jan 2007 at 12:54 Just a thought: tyres are directional so it may be worth double checking this. I can't really tell from the picture but the top picture seems to be showing the directional arrow the wrong way round, but I can't be sure

Ill change to another brand and let you all know if it makes a difference. Thanks for all your comments As a new user today, I think the timings and responses are excellent. Im sure to be a regular user.

My under powered 2.2 has to be pushed hard before the back end begins to step out.
