I was driving home today and noticed that the car felt very unstable. It felt like everytime I let off the accelerator at all the rear of the car would push out to the right, causing me to have to correct it with the steering wheel. Under braking this was even more pronounced, and under heavy braking it seemed almost out of control.

This was in 40-60 MPH traffic. Roads were wet and temperature is in the upper 30s, so I thought maybe it was somehow related to the road conditions, but it seemed a bit extreme so I thought I'd check and see if this is an indicator of anything... maybe diff or transmission related?

Tires are definitely not for cold weather, RE01Rs, but I have not experience this "pushing" of the rear under deceleration before. Thoughts?

 

Low tire pressure is the first thing I'd check.

 

 

Just checked tire pressures. Temperature is 35 degrees outside and car has been sitting for about 5 hours. Fronts are at 30 psi, rears at 28 psi.

 

I had the same problem. Tire pressure was spot on. Turned out to be a bad (very bad) left rear wheel bearing/hub
