Socket Size to Remove Nuts on Axle Bearings?

On a 2014 Freightliner Cascadia DD15, what socket or tool do I use to remove the nuts holding the axle bearings? I’ve watched some videos where they use some weird socket meant for this very purpose. What’s the name and the size that I need?

 

I just call them wheel bearing sockets. Can't really tell you what size though. They vary by axle manufacturer and model.

 

Mine is a 4 inch one on my truck . I think was about 30 bucks . I carry it in my side box just in case .

 

Where did you buy yours? Do you think Freightliner will carry mine? Or maybe I can get the correct size from them, and then buy it online. I wonder if there are two nuts of different sizes holding the bearings.

 

Should be able to buy the socket(s) just about anywhere that sells tools. Pretty common item.

 

Any truck parts house usually has a board up on the wall with a good selection of axel nut sockets.
If all else fails you could do it the old school way with a hammer and a chisel.
Not really recommend though lol

 

I think I got mine off Amazon if I remember right . Like others said any parts place or dealer should have them

 

Just use a hammer and chisel to take them off, the shouldn't be that tight. Then take em into any decent truck parts house and get the right sized socket

 

If you have a Harbor Freight near you you can get digital calipers for like 15 or $20. The calipers will tell you what size the nut is. If you do not already have a set, they are a handy tool to have

The transaxle store near me is pretty good on their prices for those sockets, but anywhere that sells heavy duty truck parts should have them, like FleetPride or Truckpro or whoever you deal with.

It's better to have the right size socket than use a chisel. You need the right size socket anyway because you have to torque them in and then check your play with a dial indicator.

 

I wouldn’t recommend a digital caliper from HF. I bought one, and it wasn’t working properly. I just went ahead and bought a manual caliper. For what I use it, it works fine.
