Rear End Shifts on Accel/Decel
Been a long time since I posted here.......have a 2013 BRZ and recently I have noticed when driving the car and accelerating up through the gears that when I shift and let off the gas and then get back on the gas, the rear end is changing directions. Can also make it do the same thing by hitting and letting off the gas. Have visually looked at the rear bushings and don't see anything wrong by the eye. Wondering if anyone else has had this problem and what it was?
Thanks. |

I'd check all drivetrain bushings - rear subframe, diff mounts, transmission and shifter mounts and engine mounts. All of these contribute to the rear being squarely.
In addition, check your suspension links, especially toe arms. Make sure everything is tight, bushings are in good shape and toe isn't out of whack (slipping or loose toe adjuster, for example). |

What are your tire pressures? What you describe is how a Torsen diff behaves when you have rear tires of different diameter, or one is at lower pressure.

I’ve also seen this when cross weight is jacked, ignore if on non adjustable spring perches.
