I'm replacing my tanabe springs with stance GR coilovers. I gave 100 dollars to the guy who sold me to replace those part with stance. after putting on the front coilovers, he couldn't take the bolt and bushing on the rear so he left it alone. so currently im running stance gr on front and tanabe springs with stock damper on the rear. we ordered those parts because none of nissan dealership had it on stock. it's been a week and we are still waiting.

but four days ago, my rear right side of my car was vibrating. it almost feels like my hub was going bad. like my wheels rotating more than it should be. left to right and up and down. it makes squeaking noise too. what could this be? could it be the sound of bushing?

 

Maybe the guy forgot to tighten the lug nuts on the right rear wheel.

 

LOL... no.. that's not the issue.

 

thats a bad axle bearing. Its fairly noisy too, almost like a worn out tire. Lift the car, grab a wheel, if you can move it around by hand while still bolted on ( takes force still)... at all, the bearing is bad.
( recently did this on mine. )
