The axle nut sockets come in 6 or 8 point.
You’ll need a new wheel seal for each hub.Rideandrepair, OLDSKOOLERnWV and nikmirbre Thank this. -
Is the one on the spider bolted or pressed? Either way you can knock them out with cam.Rideandrepair Thanks this.

Ive given up for today.......Im just frustrated with it. Didnt know Id have to pull the hub. And even more so that I went all the way to Truck Pro 2x and still got the wrong locknut......So, I sent my wife up there this time to exchange for 8 point locknuts


At least ill have all the proper tools to do the job correctly next time. Can someone give me a link to a S Cam Bushing driver install/remove tool
And also, the tool for wheel seal install?Rideandrepair and OLDSKOOLERnWV Thank this. -
If you were doing this a few weeks ago I could have taken pictures on how to do it without removing the hub. Couple trailers with pressed bushings
and never pulled the hub.
If you're replacing the cam, just torch it off.Rideandrepair and OLDSKOOLERnWV Thank this.
