Vibrations in the rear of the car?

Exhaust · 12-25-2015, 10:58 PM

Hello everyone so I am trying to figure out these vibrations that are being translated to the rear of my car. I used to always mount my gopro on the rear window with the suction mount but noticed it kept falling off recently. After I recorded a video tonight I see what the issue is, there is a **** load of vibration on my rear window now and im not sure why.

I recently took my car in for an oil change and they did tell me I needed an alignment but its minor and is not needed immediately. I plan to get it done when my trip finishes but the vibration has me feeling a little off. Any ideas? Tire pressure is good on the rears.

Edit: To add, I dont notice any vibration in the car while I'm driving, no notice of handling difference however watching the video it seems it only happens at high speeds (60+).

Uneven rear tires wear.?Tires out of balancing.?Bent drive shaft.?

Since you are not feeling any vibration, it sounds like the hatch is not sealing tight enough and starts vibrating at higher speeds. IIRC, there is a procedure for adjusting the latch in the FSM.

I had them balanced when I got them replaced.

Weird I'm not getting the light.

I'll do a drive tomorrow with the windows up. It could have been poorly secured and I also had the windows down. So this could just be me being ridiculous.

The stock GoPro mount is not sufficient to eliminate vibration at speed, even when mounted on the window glass. Look into getting a RAM Mount suction cup with GoPro adapter:

If you have summer tiers or stock tiers in cold weather, they become like pastic and on high speeds like 60 mph will make em bounce, and that feeling is it.

Check your tires you might have flat patches on your tires cuz of not using your car often. Hope you get your Z fixed.
