Link to Orangatang Wheel Replacements  FAQ: Will these fit my XL Crazy Carts- YES Will these fit my Standard size black frame cart- YES   Will these fit my Standard Red frame cart- YES Are these casters rebuildable? YES Casters are rebuildable, Send in casters and we can replace center bearing and shim them. Can I run other wheels in the casters?- YES however we recommend the yellow Durian to be the best wheel for the crazy carts. The softer the wheel the more grip you have but the faster they wear out. Running good bearings is another crucial thing as the casters are side-loading the wheel and bearings. This causes excess heat to the bearing and wheels.  Please feel free to email us if you have any other questions.
