Omega Owners Forum - Groaning noise?

Opti Omega Lord Offline Not as smart as his avatar Posts: 5372 South Lincolnshire Gender:	Groaning noise? 22. Mar 2011 at 19:07 Every time I drive my 2.6 very slowly over badly pitted/rutted roads the rear of the car seems to groan/knock. It does not affect the way the car drives ........but it is annoying. My ex-plod 3.2 estate made exactly the same noise. I never did find out the cause. Is it a case of "they all do that Sir?" Any ideas please?

Mine was making both those noises until a month ago when I changed the subframe bushes. That stopped the creaking Thumbs Up!

The clunking continued though so I changed the dampers on Saturday.... peace at last

When I got the old shock absorbers off I discovered that one had rusted through from the outside Huh

there was hardly any oil left in it and oil bubbled through the rust hole when I tried moving it but the outside wasn't wet at all. Wierd.

The noise emanates from me, not the car though. Hope you find/fix the problem soon, sorry I was no help.

Rear donut bushes are around £40 a pair..best place is AllgermanParts...website details aon forum and the guy to speak with is Jason.

Shocks are dependant on if car is fitted with self levelling or not...former are around £150 a pair on trade card,but standards are considerably less.

So for peace of mind and no more noises expect worst case of £200..plus your time to replace.

As posted by Amba: I got Lemforder bushes from AllgermanParts for about £40 and self levelling rear dampers from andyc at £150 (TC price).

The dampers were easy to fit Thumbs Up!

fitting the donut bushes was 'character forming' Cheesy
