so i'm driving after getting my car washed and go over a few humps, i slow down as always but can feel it bottoming out even at low speeds. i dont pay too much attention to it and figure its just because my car is so low since lowering with star. I keep driving on a street with no humps and as i'm picking up speed i feel a shake from the rear, pretty noticeable. I pull over thinking its a flat tire or a bent wheel(possibly from the bottoming out on the humps but everything appears fine. I get to where i'm going and park. 20 minutes later i leave to go home and for the first few miles it drove fine and all of a sudden again i feel this vibration/shaking from the rear. have no idea what it could be, has anyone experienced something like this?

 

maybe loose wheel bolts

or subframe bolt broke ?

or camber blow out soon

 

how do i check any or all of the above?

 

Loose bolt could be checked with a spanner or a torque wrench

Subframe bolt will feel like there is a dead body in the trunk - going over the bumps will feel like , there are no shock absorbers in the back

and the subframe hits the body and makes a dead body thud sound

Camber - I have no clue about this one

 

Does it help if I tell you guys that it doesn't do it all the time? It did it twice, it's not consistent.

 

I'm gonna go for a ride to see if it happens again. Will report back shortly

 

camber...if your tire is very used in the inside tread.... it will shake very badly ( most of the time at lower speed ) and will blow out

 

tires are new.

 

just went for a quick drive and everything seems ok. i drove it raised as well as in comfort and sport 2, didnt do anything. got up to 65mph and all was normal. wtf could it have been?

 

I'm not sure then

The subframe is a constant thing and won't just come and go.

 

i guess i'm relieved but also curious.
