I recently had to replace my front hubs. The first units I went with were NAPA hubs. Cleaned all the gunk from the knuckle, axle shaft and all bolts. Greased the hub surfaces and anti seized the bolts. Reinstalled torquing the mounting bolts to 150 ft lbs and the axle nut to 260 ft lbs. I've read those torque specs numerous places. I did however see the write up here say 185 ft lbs for the axle nut. Everything went in easy, straight and smooth. Those lasted all of 300 miles. I returned them under warranty and upgraded to the SKF like I originally wanted. Followed the same procedure to install the SKF units. I haven't driven the truck since I've installed these because while the truck is still on jack stands the wheels wobble like the bearings are loose even after the mounting bolts and axle nut is torqued. I can't see anything else really moving when I shake the tire from the sides and top and bottom, but it's hard to tell doing it on my own. It's not a large amount of play but it still plays. Is there something else that could cause this? U joints, ball joints or steering components? Truck has 248,000 miles and I'm not sure what the previous owner has done or replaced. No death wobble on the original or previously replaced hubs, just the low speed groan and grind sound that went away after changing but came back with the NAPA units. I'd like to find the issue before I destroy the new SKF units. Thanks in advance.
