I have a 2013 RE 130 rear engine rider. I just jacked up the mower to remove a front tire and I notice how much the front tires wobble. I took them both off the their is an incredible amount of play in all of the front wheel bearings. The bearings seem intact with not missing ball bearings but you can literally move each tire sideways about a 1/2". I have some bulges in one of the tubeless tire side walls. Does anyone have a source for some after market front wheel assemblies with better bearings and 4 ply tires? Front tire assembly is 7105138YP Tire is 11 X 4.00 - 4.
