Bought 4 trailer hubs and had less than 400 miles and six months on trailer when 1 lug stud became loose. Hubs are called vortex and come with 6 yr warranty After multiple phone calls and emailing pictures as well as written account , warranty denied because I torqued lug nuts to 80 lbs and rechecked at approx 20 miles. Per Juan at tie down it should have been 90 lbs and 50 miles. I use steel rims 80lbs was proper torque. If this is how it works with a small item I can only imagine how they would squirm out of a more expensive item on warranty. Shop somewhere else!!
