When I am driving at any speed and I take a curve in the highway going left, the car shakes pretty bad. Any ideas? Tie rod? Struts? Bad wheel bearing?
It also shutters when decelerating from highway speed when I let off the gas but when I give it a bit of throttle, the shuttering goes away.
I'm using banzai racing motor mounts, would thar explain the low-ish rpm decel shaking?

 

How are you using our motor mounts with the 13b-rew?

Motor mounts will not cause any shaking while turning. You have a problem with your steering components. I would check the lower ball joints.

 

Have those motive fab adapters to get the REW in the FC.

I'm not blaming the mounts for the shaking while turning, but I know (or read) that some stiffer mounts cause vibration at lower RPM.

I shall check my lower ball joints though, thanks

 

more important check passenger front wheel bearing , very common , also try breaking heavily it should pull to the left pretty hard.

 

Will do. So if the passenger side wheel bearing is bad, then it will pull to the left while braking/show symptoms while curving left (not turning)?

 

couple things it could do , it can hum either a little to a lot , cv joints and bearings can pull to the opposite side of the vehicle under hard braking(when driving straight just cruising no problems ) but cvs on these cars are the rear so kinda not an issue

 

Doesnt pull when braking that I noticed

 

Hard braking ? Try to do a complete stop from 35-40 without holding the wheel

 

I'm sorry, why was that not checked yet?
