I am running out of ideas of what my vibrations are caused by on highway
#107
So with these vibrations my car vibrates more and has this grinding feel/low key noise coming from the car when going down hill..when i am at bottom of hill, it smooths out but not all the time.
As soon as my car sense a hill..it vibrates in the seat a great deal and you can hear this low key grinding noise. Someone today said it's my rotors..is this true?

My rear rotors do have some uneven groves in them..going to see if the tire place and machine them down to make them smooth

I had an appointment to get roadforce balancing on my wheels (roadforce balanced from the Tirerack when mounted) and was considering an alignment but that fell through. So I decide to replace my rear rotors and pads since the original oe pads had less than 5,000 miles left on them and some had reported improvement in vibration after doing the rears. Well guess what? The vibration I have at 75-85 mph really did improve! There is some vibration still but it feels more like road imperfections now and not the shake of imbalance.

Yes, there was some shaking in the steering wheel. It is not as bad as what you had described though--certainly does not tire out my arms. Felt just like slight imbalance in the wheels. I did rotate the tires and the vibration was still there, more or less the same intensity. I do not generally balance my wheel/tires after mounting a new set but thought this might be the first time for me. I only have about 6000 miles on the wheels/tires though so I was doubtful that it was the balance but was at my wits end. I definitely ruled out a spacer issue since the vibration was still there after I took them off. I also had a recent alignment at the dealership but they saw my suspension stuff and said they could not guarantee anything except it that it drives straight(!!!).

Can't believe it can't be fixed. 3 mechanics said they cant find whats wrong. Yet the symptoms are so cut and dry:
-Vibs for 8-10 seconds then 8-10 seconds of clear sailing..and this process repeats over and over again
-Also, when wheel is turned on highway going around turns...vibrations almost all go away..once i let my wheel go strait again..boom its back to vibrating bad
-19 inch tires and wheels made it 100 times worse..and i didn't think that was possible.
This is what i am still stumped about: When i had one tire shop balance my wheels about 2 months ago...it was silky smooth for 3-4 weeks until it started getting worse again..and now i cant get it back to the point of what it once was...

check your drive line, rear axle, transmission and engine mounts.
Also you need to eliminate all things possible to know where to look for vibrations.
To eliminate engine as a problem area
Get up to speed until you start getting vibration, let off the throttle and see if vibration goes away right away or only if car slows down
To eliminate transmission as a problem area
Get up to speed until you start getting vibration, put transmission in N and see if that does anything to a transmission.
If you eliminate engine and trans as a problem area, check your drive line for loose mounts or bolts.
Also check mounting bolts on rear pumpkin, make sure they are not loose.

Dealer checked all of those..trans..diff..rack..suspension..u joints..axles..everything
Basically myself and the dealer has eliminated everything. Dealer said there is nothing else they can look at and that they have never seen this before..so i am SOL...thats why i am trying to sell this thing ASAP
