Morning chaps,

Slowly working getting the Omega to drive as well as it's 60,000 miles and clean bodywork suggest it should.

Latest thing I'm working on and genning myself up on is Omega suspension bushings. I have a wobble at around 45-60 and also a vibration through the steering when braking.

The discs and pads are getting changed regardless just because maintenance and I'm getting the balancing on the wheels double checked unrelated to this.

What I've found in terms of movement with the car up in the air is in the steering rack/arms. If you wobble the NS wheel holding it at 9 and 3 position there is a good amount of movement around the steering drop arm, what bushes are likely to cause this? I know the arm itself is bushed at one end, is there anything else on the rack that is a usual culprit to cause a couple of mm of play with the wheel in the air - or is this level of play expected?

Pictured is what looks like where the most amount of movement is happening.



I've had a search around this topic on the forum, couldn't find anything too relevant, apologies if this has been covered a thousand times.

Replace the idler arm. Ideally with a genuine one.

The culprit is the opposite end of the idler arm to what you have circled.

If that's failed at that mileage the rest of the front suspension won't be far behind it.

Thank you for confirming. Idler arm is what I meant by ‘steering drop arm’. I could see it’s bushed one side.

I’ll get that replaced and start building up a front suspension refresh kit in the meantime.

Cheers for the advice

Good you're going to check the wheel balances.  Would cause steering wheel vibration through a narrow speed range, 50-60 as I recall. 

Re. vibration under braking, do replace the idler but if still there this was common on both my migs.  I think caused by uneven disk wear arising from  sudden braking.  You can change the disks but I found it disappears after a few hundred miles of smooth braking. Until the next time you slam on the brakes then it comes back.
