996 suspension issues
Discussion
Was out in my 996 C4S on Saturday and going around a long tight right hander that then switches to a tight left (M25 to M11 Junction) when the traction light came on. Nothing untoward about that, but then, when joining the M11 from the slip road, the car seemed to wobble. By that I mean that when I changed lane and straightened up, the car then seemed to wobble side to side. From then on every lane change felt the same - a delayed body roll. It felt a little like the tyre had gone, but I stopped all four were fine.
I had the car MOT'd in March and there was an advisory about worn suspension bushes that would need looking in the medium term. The car then had new rear tyres and geo set up just 3 weeks ago where I was told that they were starting to detach, but were still good for a while yet.
Given all of this, I can only assume that the hard cornering might have been the final hurrah for the bushes and the wobbling/excess body roll that I am experiencing now is a result.
Anyone had similar experiences with knackered 996 suspension?
Hoping to get a bit of an online diagnosis if possible before I take my car to a garage - mainly because I wont have much time in the next 3-4 weeks to do so and will need to use the car in the meantime (2 weekends away visiting friends).

detached bushes were only a guess. There is no knocking, clonking, crashing sound at all, just the lack of tightness and delayed movement that I mentioned. I guess if the bushes were detached, then I would hear metal on metal clonking over bumps etc?
Hmmm.. might have to make a few calls tomorrow.

If its not the loose wheel nuts I would say definitely an issue with the bushes. Were you advised of any in particular as I would suspect, from experience the rear coffin arms will be to blame.
I had an advisory of play in them but didn't fail an MOT. But I had noticed the rear of the car felt loose, even at slow speeds over humps and poor road surfaces, including crossing the lane markings. My tyres were also wearing badly, and very quickly with feathered edges to the tread blocks.
Hope it's just loose nuts for a cheap fix ;-)

Check your front wheel bearings. On a 911 they don't tend to grumble like most cars.
Grab the wheel at the top and shake it with your full weight and see if theres any play. If there is some play get under the car and have someone shake the wheel while you feel around at joints for the play. If the play is from the wheel bearing then you will feel it between the caliper and the disk.
Check your top mounts by removing the plastic covers either side of the battery and flicking off the black circular covers. Crouch in the front boot and put your finger in the gap between nut and body and bounce up and down. You will feel like a nutter but if you feel play there they might be on the way out.

Long time thread resurrection, but... Has anyone done this top mount check? The black circular covers didn't want to flick off. Before I apply too much brute force can anyone tell me if it's supposed to require small amounts of effort? Thanks.The black plastic caps over the top mounts can easily be removed with the help of a flat bladed screwdriver.
The rubber top mount is obscured by a large saucer shaped washer. It you look closely it may be possible to see if the rubber is cracked around the circumference. Its should be firm and crack free. My 996 turbo top mounts were completely shagged at 60K miles.
