It's good to know about the Yukon hubs, but I don't think Genos sells them. Looking at their web site all I saw was Spin Tech. There are also several other brands, but I thought if the Spin Techs were good I would buy them from Genos.
I haul a camper around 7-8k miles per year with our truck and would certainly feel better knowing I had serviceable bearings on it than what Dodge installed at the factory. I'll probably get the Spin Tech.
All my previous trucks had serviceable bearings much like the kits, the last being a '89 W250 we had for 23 years, a great truck, but with no noticeable suspension.
Thanks for your help.
