This was my last option to get my trailer up and moving. I searched all over for just a new hub. No dice. This spindle and hun actually saved me $$! Tip: find a welder with skill and who is not going to take the short way out. Welders are not cheap but compared to an entire axle or replacing a trailer…..worth the $$
