I just replaced my F+R rotors (drilled/ slotted) n pads. Before i replace my rotors while i hit the brake pedal @80 mph the G lil shaking from the brakes but under 80mph was okay.after i put new rotors+ pads n doing brake @ any speed , the brakes are very smooth.but theres another shaking problem,the shaking start from 50-70mph on straight road.if i drive the car over 70mph the G is fine or if i drive between 60-70mph on light curve road the G is fine too.so the G
is there anybody had like this experience with the G ?? any help n comments ,thank you.

 

So is it just shaking at a certain speed or is it shaking while you are braking?

 

Only @ certain speed, between 50-70mph.under 50mph no shake at all n over 70mph not shaking either.n i took the G to local balancing tire shop its says the tire was balanced then i try to drive it again between 50-70mph still shake like before get balancing.

 

Possibly wheel bearings

 

op jack your car up and look at your bushings, my car use to shake above 80 also. Turned out to be my
lower compression rod bushing, good luck!

Thank you all. Tomorrow ill try bring the G to infiniti.

 

Update?

 

OP This happened to me. First I would make sure your wheels are secure and tightened down.
I used a air gun and somehow one wheel did not get tightened all the way.. Learned my lesson to always check by hand..

 

I also say check the bushings. Had the same problem and thought my rotors were warped but it turned out to be my LCA bushings and Compression Rod bushings

 

If everything mentioned above checks out. Find out if you're wheels are still correctly balanced.
