Can someone answer what the symptoms would be with the following (including bushings/mounts);

Worn out Watt's linkage

Worn out control arms

Worn out rear sway bar end links

I'm having some kind of loose feeling coming from the rear of the car. It's not a normal bouncy feeling, but more like a sideways motion. Really hard to explain, but imagine someone is pushing your car hard from the side while you sit in it. That's what it feels like when I drive.

I recently had the car in for inspection, and they didn't notice any problems in the rear. Just that the front sway bar end links were worn out. So I replaced those, and it made it more noticable that the loose feeling is coming from the rear. Before it was kind of hard to tell where it came from.

Car has around 124k miles iirc

Might help if you jack up the rear of the car,put jackstands under the frame & let the rear end hang unsupported.Then,have someone push & pull the rear wheels from side to side while you look to see if any of the rubber bushings are worn out or parts are loose.

Good luck, DDK

If its not tires, then its a bushing either in the control arms or the watts link. Push on the rear 1/4 panel while watching the wheel and tire in relation to the wheel well, there should be little to no movement between the wheel and body.

It's not tire pressure. It was the first thing I checked. And there is movement of the body in relation to the tires if I push the car sideways. Quite alot actually. I'll take a look with car jacked up when I change to my summer tires.

In all those cases, check the Watt's linkage, especially the pivot on the axle pumpkin.

Since you're at about 124,xxx miles, my guess is it's about time to replace the whole lot of steering and suspension joints and bushings. You can expect at least 100,000 miles out of that stuff, and how much more is a matter of luck. Age is also a factor. What year is your car?

My preference is to do everything at once to avoid multiple alignments. When my 2000 MGM needed doing, I started with the various joints in the front and learned the hard way how important the control arm bushings and stabilizer bar bushings are on these cars. After pretty much everything in the front was done (except springs and shocks, which still seem okay), I was getting an obvious swaying motion when stopped at a red light in high wind. I also felt some side-to-side motions on the highway in certain circumstances, though not as bad as I've seen others describe. All of that improved after replacing the rear arms, Watts link, and stabilizer links and bushings. It's a lot of work, but you potentially double the typical lifespan of your car.

Ive had that issue if I put my tire pressure up too much. I'm running Perellis good up to 51psi. If I go above 44psi, the rear end feels all over the place.

First questions is What year is the car?? There were big changes in the rear suspension in 1998.

This is still a helpful thread to me. I also have some looseness and a shaking with highway speed corners.

As an owner of two CNG cars, my 2003 with extended tanks is solid as a rock. All the bushings etc look fine.

My 2000 LX was wobble crazy, with only four tanks. I replaced the sway bar and added ES bushings, new Bilsteins and new Moog cargo coil springs. Still wobble-wobble. Lifted my rear end off the ground and "twisted" my control arms with my had. The bushings were like marshmallows. I ordered some control arms from CHE Performance....WOW! Wobble was reduced significantly and the ride was a lot better. However, I think with an upgraded Watts link, that'll finish it off.
