Hi guys, my RRS makes humming noise, not continuous but rather ahm-ahm-ahm-ahm, most prominent at 25-28 mph.
If someone had similar issue resolved or have an idea please chip in.
Lets exclude few items:
Lower control arms new
Toe Rods new
Wheel Bearing are new
Active sway assembly is new
Michelin Latitude tires are new
Wheel alignment is done
There are few theories:
-Brake rotor has a side play and catches on a pad.
-Rim has lateral damage/defect '
-Something to do with front drive shaft (this idea was developed by LR Mechanic)
I hear/feel that ahm-ahm rather on the vehicle floor, pedals, not a steering wheel, vould not replicate it driving it in the lift wheels in the air.
Guys, thanks in advance for your input.
