New noise after close collision
 

So I was driving on the freeway this morning going 60 in a 50 mph zone (not as bad as it sounds, its one of those freeways where if you drive at the speed limit you will get mowed down). It was a 4 lane freeway and I was second from the left. A lady in a large SUV from the far right lane cut into the second lame from the right(next to me) going at least 70. When she realized that there was a Uhaul truck in front of her doing around 40, she panicked and slammed on the brakes hard and swerved into my lane in front of me. I noticed she was going too fast in her lane and I was driving defensively in case this would happen. I slammed on my brakes and skidded to mere inches away from her bumper while violently pounding my horn. Needless to say, when I recovered, I drove next to her and flipped her off. But now, I hear a strange new noise I haven't hear before coming from what I believe is my rear axle or brakes or something. The best way I could describe it is like how your shoes would step on a sticky floor and just make that peeling sound as you step off of it. Except that it is happening about 6 times per second, and only at higher speeds (40+). Is this something I should be worried about? Should I go get it checked out by my dealership's mechanic?

the easy to read version:


I had to apply my brakes really hard, skidding in the processes.

now there is a strange noise coming from the back of the car, best way to describe is is like that sound your shoes make when you walk on a sticky floor.
This happens about 6 times per second at higher speeds (above 40mph)

can anyone help?

two things that i can think of

1. you might have picked up a foreign object, like a screw or something. Check your rear tires, are you still holding air?

2. you might have flatspotted a tire or two, which is really weird cuz you have ABS, but non the less that is a possibility.


general thoughts, if its happening fast and only noticeable with speed, it's something to do with the rotating bits.

i would first do my own visual inspection on all rotating components, see if anything is loose and interfering

then i'd go to the dealer.

was this the first time you heavily applied the brakes?

this could be a case of uneven build up of pad material on the rotor surface, you may look up bedding pads and rotors and try that procedure, basically a series of heavy braking from 60-~10mph no stopping then cooling off by driving without stopping completely...


otherwise there is no good reason you should flat spot tires with ABS and you should not be able to hurt the car in stock configuration by applying the brakes in the manner you described

There are a lot of tire repair parts below the trunk floor board. Is it possible one of the items might have come out of it's individual pocket and is making a rattle/vibration sound?

Id say get your rear brakes checked.
