My son purchased his beautiful 09 Aspen earlier this year, love's it, he and family are presently towing their new 29 foot trailer around the Gaspe coast.

On uphill climbs at about 55 mph/90 kph there is a bearing grinding noise, and if he presses the tow/haul switch the noise stops.

Now he also told me last night that it does the same thing when going up an incline at 25 mph/40 km per hour and when he presses the tow/haul switch
it stops.

Anyone else have this issue, I am new to this forum, I went through all 32 pages of issues with the Aspen and also tried several searches here but found nothing.

Thank you, Eugene.

 

I meant to state that the 25 mph hill climb is without a trailer in tow.
