After much abuse and 0 maintenance.
Under extremely dusty conditions.
Might right side rear wheel bearing finally went out.
Replacing all four at a cost of $8.
Tekno IMO,is if not the(never say never)best,one of the very best slash axle upgrades.
In this same time period,I have replaced the velineon motor bearings three times.
Dust stinks and is hard on everything.
But Tekno axle set ups ROCK!!!!.
