Vibration
Hi, hope this is the right place.
New (to me) 2011 HHR.
Wheels were balanced, alignment done.
Above 60mph there is a vibration. Frequency is akin to driving on a rumble strip, but a lot less "volume". Just an ever so slight feel in the ass and wheel.
And, it's intermittent. Seems to start after a few miles at speed, and then sometimes it goes away for a (short) while....
Riddle me that one Batman......

Bad Balance or lost wheel weight.
Bad wheel mounting, especially if you have aftermarket wheels. Some aftermarket wheels do NOT have the relief for the production washers that are installed on the rotors (generally 2). If this is the case, remove the wheel and then remove the production washer that is in tight contact with the rotor and drum, and reinstall the wheel. The washers are thin metal and can be cut or pulled off.
If the vibration started just after the work you listed, the problem would need to be something in that process.
You are not speaking of vibration when applying the brakes....correct.

Factory steel wheels with genuine plastic covers.
23k Miles, tires look original.
Vibration was there before they balanced/alinged which is why I made them do it.
I don't suspect the wheels because that would not be intermittent......

I went round and round on this awhile back..different rims..tires..balancing ..didnt quit until brakes were changed..suspect rotor out of balance, no they werent pulsating. Only thing left after that would have been hubs....

Ah yes, forgot, brakes not pulsating. But new rotors may still be the ticket.
As I said, it's intermittent, so there is some sort of harmonic vibration going on.
If the rotors are part of that "game" then replacing them may break the chain.
I'll think about it.
