Its heavy duty that's for sure. I don't see difference between this item and the otc brand. Its a fraction of the cost of otc yet well built I don't see how u can break it.
Bought to change the bearings in my ford superduty rear end.I have not used yet but am keeping it around in case I do need it.Seams to be good quality.
I don't know why people have had problems with it being too small for any Dana axel. I've been using it on a Dana 80 and it works perfect for me. It is very well built. It is heavy but I assemble it on the axel which makes it no big deal to get it on the axel.
