    Wobble in rear suspension

    Hi all, thoughts please....?
    Symptom is as follows - when cornering around a left hand bend at speed (over 80kmph, say), the rear suspension seems to 'wobble', or maybe 'sway' is a better term. There is no symptom around a bend to the right.
    I am thinking the issue is either in the right rear shock absorber or the dynamic response stabilizer bar.
    The symptom is as if during the bend to the left, the stabilizer tries to engage, but then fails, then tries again, then fails. The problem exists whether I have the car in Dynamic mode or not. Dynamic response reservoir is not at max, but not at minimum either, so I don't think there is a leak. No obvious fault codes.
    Anyone else had this sort of symptom?
    Over normal bumps, the shock absorber seems to be doing its thing, so I could be up for a replacement dynamic response stabilizer bar.
    thanks.

    I might very well be over simplifying this, but wouldn’t the shock only control up/down movement - but the stabiliser bar controls left/right and twisting?

    Are there bushes on the stabiliser bar? Could the bushes be perished?

    Thanks for the feedback.... yes I am thinking more unlikely to be the shock absorber, and more likely the stabilizer bar, but not sure how the symptom appears in one direction only.
    I checked the stabilizer bushes, they seem to be in good condition - no signs of movement.

    Replace them anyway. They ae cheap and easy to do. Mine had similar symptons and when I replaced the bushes it resolved the problem.
