I recently dropped my 06 base sedan on Tein 350z h. techs and have been driving fine, i had the car aligned right away. It has been 1k since the drop and this wobble sound has been going through the car, its very noticable going downhill at about 25 mph and no acceleration. I thought it was the tires or balance, had them checked and they are ok. Im on oem suspension besides the springs, what could be causing this?

 

make sure the wheels are on properly and check your bearings

 

+1^check wheel bearings

 

sounds like ur shocks/struts are worned out. If its the wheel bearing it'll sound like your driving an airplane.

 

could also be your tires maybe are unbalanced? or even bent rim. i know my bro had a bent rim and his thing wobbled a lot..

 

not always. only if you let it go too far.

 

how loud is the wheel bearing issue when they go out?

 

Its odd because when i brake to corner the sound gets louder and deeper. Im actually thinking it could be warped rotors. When i get the wheels rebalanced i will check brakes also. I dont think its the shock, the car doesnt feel bouncy yet, but i am getting tokico hp this summer.

 

try turning without braking and see if it gets louder. if so you are most likely looking at a bearing issue

also check if the hub might have rust build up on it, if so clean it up and reposition the rotor.

 

might be able to check the bearing quick by jacking up the front end to get the front off the ground. grab the tire on the left and right and wiggle it. you shouldnt get too much play. if you do id agree with everyone else and say bearing
