I am installing a new bearing hub assembly on the RH front axle. The new bearing (Timken SP580100) has a larger pilot diameter on the hub which makes it not fit into the dually front wheel spacer. The diameter is about a 1/4" larger than the original. Has anyone else had this problem?

The bearing came in a Timken box with the correct part number clearly on it.

 

if the number on the old bearing itself matches the number on the new bearing itself then that would be the strangest thing i've seen in a while. wouldn't know where to send you if that's the case. good luck

 

Looks like I ordered the wrong bearing. The dual rear wheel trucks require a different bearing. I need part SP5801002, not SP580100. Oh well, I wasted another day messing around.

 

don't sweat it, it's only time
