Should Trailer Axle Be Bowed Down in Middle  

Your Gatormade axle will need these brakes. The Dexter Electric Trailer Brake Kit - 12-1/4" - LH/RH - 8K, part #DX32QR, will fit your Gatormade Aardvark. These brakes are rated for axles rated for 8,000 lbs. I have included a product description…

Trailer axles typically have the bow you mentioned in them to help compensate for the vertical load they bear and still have proper wheel camber. This way when the load is put on them the axle will flatten out and the wheels will be aligned properly.…

After you've packed the bearings and assembled everything, carefully slide the hub assembly onto the spindle and install the outer bearing. Install the spindle and tang washer and run the spindle nut down finger tight, then rotate the hub back…

The Dexter 12K oil bath axles can be changed over to grease without any issues. The oil does keep the bearings lubricated well, but there is a much higher risk of leaking which leads to a much higher risk of failure. I'd personally move to grease…
