Does anyone have a Quickie QM-710 and notice that it makes squeaking and cracking noises from the back when you go over the slightest bump? I got this power wheelchair back in October 2017, and despite my caregivers drying it off quickly when I come in form the rain, or dusting it in the dry summer air, it still has been making these noises. I have checked and nothing is loose or broken off. It doesn't matter what speed profile I have it on or if the tilt/recline are activated, it still makes these noises when I got over the tinest bump on the sidewalk.
Is this common for this model of power wheelchair? I swear, this power chair sounds like something I've had for years rather than months.
