Car gets stuck leaning left/right

[bsimonson]

Hi,

Today I made a thorough clean of the car as the winter has arrived here in Stockholm and I won't be driving it anymore until April

Anyway, I raised each side in turn to get the wheels off but when I put the car back down again it still leaned a fair bit to each side. That is, when I had had the left side in the air it still leaned to the right when back on all four (and vice versa).

When I got in and drove it just a short bit I could feel that it suddenly (but sort of soft) got back to a more balanced stance. There was also a qureeking sound.

Does anyone have any idea what could cause this?

That is the normal stiction/hysteresis in the rubber bushings (or urethane).

The only cure is to fit something like needle bearings, monoballs, or Rebel Racing A-arm bushings which move smoothly and with little friction.

Thanks. Any specific bushes or all of them? Does it get worse over time/is it something that should be fixed?

Cheers, Björn

When you were jacking the car up did you leave the hand brake on? I've noticed my 911 does this when jacked up but flattens when released.

In addition to what Flieger said, the suspension experiences a lot of track change as it travels. Once the tires touch the ground when setting the car down, they don't allow the track change (they want to slide sideways as the suspension compresses), which tends to leave the suspension high. Rolling the car back & forth a bit will allow the track to change to where it wants to be, and the car will return closer to its normal height.

The hysteresis in the bushings et al is best fixed by going for a drive... it doesn't harm anything & is normal for any car.

Ok, that makes sense. Thanks.

@michaelg500: Yes the handbrake was applied and the car leveled out as I moved it a bit.


Cheers, Björn

Perfectly normal.
