Tires: strange tire noise, goodyear eagle rsa, radial runout

Question
The vehicle is a 2004 Cadillac SRX with rear wheel drive(not AWD), V-6 with 17 inch wheels and 17,000 miles. The vehicle has constant load moaning noise from the right front at 60 mph and above. The noise is intermitent at 45 to 60.  The noise ocillates below 60 at about 45 groans per minute. The car does not vibrate but there is a slight vibration felt in the steering wheel when the noise occurs. Wheels were checked and found to be within specs(less than 0.005 radial runout and 0.010 lateral runout). Brake rotors were checked and were acceptable at 0.001 runout. Both right and left wheel bearings fell tight(unloaded) and all ball joints were tight. Brakes are free with no drag. This problem occured after the left front wheel impacted a solid object on the highway which busted the original tire and slightly cracked the original wheel. A new tire and wheel was installed. No other front end damage was found and the front end fell into alignment tolerances. A dealer said the noise was caused by tire wear on the right side so I put a new tire on the right front. This made no difference. Both tires were replaced with the same tires that originally came on the car(OEM Goodyear Eagle RSA, P235/65R17 ).
Any ideas? Thanks

Answer
Don,

I don't think you're hearing a tire noise.  The proof is that you didn't have a problem before the impact and now changing tires has no effect.

I would start looking at wheel bearings, suspension bushings, etc. - something mechanical in the suspension or the steering linkage.

Hope this helps.
