Its been a nice warm day and I'm installing the adjustable camber arms I put together during winter. While doing so, I thought I would look for a problem somewhere in the 6 link setup. She occasionally goes squirrely on me with the rear end hopping maybe a 1/2 inch to one side, then the other, in curves when pavement is wet, with it being especially bad (to the point of needing to slow down to 20 mph on interstate) when cold and minor amounts of snow/ice on roadway. I've had 3 trustworthy mechanics look without being unable to find a problem. I had thought I might find a worn bushing, but I didn't. All links and the anti-sway bar seem to be fine.

I've wondered about faulty electronics, maybe the traction control system going weird, or possibly the stability control, so I've looked for breaks in undercar wire insulation but I didn't see any.

Thoughts are welcomed.

What tires?

 

sounds like your sub-frame bushings are going
there are 4 of them,,,,,, put the car on a lift then see if you can lift the rear end ,,,with a jack of course. it should lift the car not the rear end. if it goes up and down they are bad,,,before you try to jack the rear see if your finger will fit between the bushing and the body,,,after jacking again try with your finger ,you should have the same space call me and i can explain better than my two finger typing.

 

There is sooooo very little I would agree with 180, but what tires are you running?
The bfg and good years will feel like your are driving on ice in colder temps, the high performance summer tires compound harden in cold temps

 

Had summer tires with similar results. Switched to all season. No more problems in cold/wet.

Tires and alignment. -toe and -caster can cause the issues you are describing, as well as warm weather compound tires that are in too cold of environment.

 

AMX1397 -- You're right. It does appear to be the sub-frame bushings -- notably the passenger side front. Replacement will provide a nice springtime project. Thank you.
