    Front hub/axle nut size


    Support FSC and see no ads! - Click Here
    I've got a 2002 Silverado K1500 and I'm trying to find out what size the hub/axle nut is. I had to have one hub replaced during a road trip and I want to do the other soon, before I end up broken down on the side of the road.

    Thanks in advance.

    36mm. The socket will have a little slop to it but thats what it is. I've not found anything else that fits any better.

    actually it will depend on the nut...most i found are 36mm, but my buddy replaced a cv shaft in his 01 and it came with a new nut and it was 35mm

    Thanks for the quick response guys, I'll go with the 36mm to start with.

    A 35mm socket fit my 99 GMT-400 better. I tapped it on with a brass hammer. The 36mm was very sloppy.

    I'll just grab both and return the one I don't need. I appreciate the input, thanks.

    I've noticed that too. The snug fit is fine but its not the correct fit but will work just fine, just have to tap the socket on and off. The 36mm works fine for 99% of all applications.

    I bought an axle nut socket set from Harbor Freight for 50 bucks that has 29mm - 38mm. I use the 30, 32, 36 and 38 regularly. The 30, 32, and 38s are your pinion nut sockets. To buy those sockets individually you are looking at 20-40 a piece depending on the brand. I got all 8 for 50 bucks.

    Harbor freight rules, especially for tools you may only use one or twice. I have a nail run from them that keeps on trucking!

    Tapping the socket on is better than fine. There's no chance of deforming the nut because it's on so snuggly. The 36mm I bought at Autozone was sloppy enough that I was concerned about rounding off the nut given the torque involved......... removing or installing.

    There are some cheap tools I won't use buy cheap impact sockets seem to be just as good as any of the others. My metric and standard impact sockets came from Walmart and are made by Stanly. They are black 10-24mm and 3/8 - 1 inch deep sockets and were 20 bucks for metric and 20 bucks for standard. Stanly owns MAC tools and I've been using them daily for 3 years without a single issue.

    Whichever size works. I've yet to see a stock axle nut that a 35mm would fit on without literally having to hammer it on there. Tapping is one thing but hammering is another. Time is money and if the 36 mm fits, doesn't round it off and the nut doesn't stick in the socket then thats what I use.
