“The assembly is quite robust but I definatly won't be using the Zip Navigator in "really" muddy wet conditions again. The conditions were the downfall of the assembly. Plastic Cog cracked on right side and chewed out and could see where the moisture had got to the bearings etc.
Otherwise I find the the Zip Navigator AT a great cart and suits my needs extremely well.”
“Easy to install. Old axle has 5,700 miles. Looked like 1 side wasn't turning so ordered the gearbox and axle. Turns out it was the wheel that was stripped. Lucklt I had extra wheels as I bought my wife new wheels for Christmas last year. Now have extra gearbox and axle assembly. Never know when you will need an extra. Only 4 stars because of cost.”
“I just replaced my gearbox. There is a youtube video that gives you step by step instructions. I drew a diagram of the bottom of the cart on a piece of cardboard. After I took the screws out, I place them onto the diagram. There is an electrical box inside. I would suggest you take a picture of the wiring or mark each wire. Once you remove the cover, there are about four screws that hold the gearbox on. Remove the gearbox. Remove the two motors from the old gearbox and assemble them on to the new gearbox. Then assemble in reverse order. Having a screwdriver that is magnetized or having a magnet may help removing some of the screws.”
