When I bought the Sendero HD, one of the first things I did was toss a fresh set of wheels on it. When I ran it, it was a little wobbly but I figured it was just the foams needing to find their happy place inside the tire. Well last night I decided I'd try to manipulate the foams to move the process along. Flipped the truck on its lid & eased on the throttle. As the wheels spun, I saw it wasn't just the tires but the wheels are wobbling. I tossed on the rtr wheels to see if the wobble went away. It didn't. Seems I've got bent axles. I have done some light crawling, but this thing was shimmying & shaking straight out the box. I ordered a set of rear shafts, but thought I'd ask here - is this a known issue? I couldn't find info on getting beefed up shafts. Maybe the tolerances are off from the factory?
