The leading cause of steering wheel vibration in Aston Martin DB11, especially when driving at high speeds, is unbalanced wheels. If only front wheels are out of balance, the vibration is typically strongest at
NO vibration in steering wheel. No 'cupping' sounds from tires. all is tight underneath. No hint, very smooth, under 65 mph. You can take out of gear at 70 and it's still there. Does not increase in sound/feel the faster you go, ideas? Thursday, January 14th, 2010 AT 2:21 PM...
The acceleration experienced at the driver's seat and the steering-wheel and the noise level at the driver's ear were measured under repeatable test conditions, on a bituminous conglomerate track, with different forward speeds and with the engine at maximum speed. Measurements of vibration and ...
I mentioned earlier in this case study that I could only feel brake judder through the steering wheel, and not inherent cabin vibration at the sweet spot of 83 mph. Looking at the data below we have captured a tyre speed/frequency second-order vibration (T2) which equates to two disturbanc...
Varied stability charts in the plane of drilling rates and rotary speeds are obtained by solving a fully coupled, two-degrees-of-freedom model using linear stability analysis without making any asymptotic assumptions. Although the steady-state motion of the bit is always unstable, the nature of ...
I also had to have the intermediate shaft replaced in the steering wheel as well as a shim, supposedly to stop the drifting to the right. I would like to know if anyone has heard noises coming from the fuel pump. Mine sounds like air escaping accompanied by a fuel line noise. jbrich...

This has nothing to do with wheel balancing. After rick case gave me back the vehicle it rode worse at low speeds and slightly better at high speeds. My buddy stayed with the shop manager for 4 hours today. They feel that the tires themselves are the problem. While going 50 mph and ...
