s14 - Feeling some shaking in the rear when I go around curves

[keefus16]

feeling some shaking in the rear when i go around curves - its only when speeding into curves and taking them hard - all stock suspensions - all bolts are tight double checked that already - no issues going over bumps other than the no shock feeling - let me know what you guys think

subframe bushings

^ +1.. Jack the rear of the car up and see if the subframe bushing look torn.

I posted a similar thread not too long ago, and was also told subframe bushings. I jacked the car up, and everything looks perfectly fine. Like, PERFECTLY fine. Could bad RUCAs cause this symptom?

are the aluminum ones the way to go - or just get the rubber ones

shocks could be blown.

Jack the rear up again and leave the rear wheels on. Shake the wheels up/down and side to side to possible see if any of the upright/Rlca bushings are shot. Visually inspect all bushings for cracks aswell. My s14 had bad rear shocks and they felt super bouncy but didnt shake at all.

It depends on what you plan to use your car for. Aluminum bushings tranfer vibrations throughout the chassis making it annoying to daily drive.

I will do this today. Visually, everything looks fine. The bushings look like they only have 25k on them (they havent been replaced though, 93k on them).

The shocks have been replaced, I know what blown rear shocks feel like. Blown shocks make everything super washy, and bouncy. This feels more like a "shimmy." Ill hit a bump in a turn or at high speeds going straight, and the back end feels like it wobbles a little back and forth. With blown shocks its much sloppier.

Yeah sounds like subframe bushings. My friends car acted the same way when hitting any bumps in the road. We replaced the subframe bushings with ES ones and it went away. Also check the sway bar bracket bushings, as they could be shot and causing the sway bar to flex the rear control arms.
