A grinding noise from the rear axle of your MN98 is often caused by worn or damaged internal gears. This is a common fault on high-torque rock crawlers after hard use. If the gears are stripped, you can either replace the internal gear set or upgrade to a complete metal Rear Axle Assembly for better durability.
