CV Axle Nut Size

[Big T]

Need to buy a socket for the CV axle nut here in Montana, as the other made the trip to Fullerton earlier this year. Is it a 36mm?

I ran into at least 2 sizes.

on my K2500 it's a 36mm

36mm is pretty standard

I believe the 2nd size I encountered was either 35 mm or 32 mm.

If I could remember which vehicle I could look it up in the maintenance books.

Do you have a Harbor Freight around?

I hate to push chinesium sockets.

I got a small set of bigger metric sockets in that size range. I believe they were 3/4" drive.

I have a 1-7/16ths socket which measures near to 37 MM. It is what I have been using on My 2000 K3500.
It does fit a tiny bit loose on the front axle nut.
I tried to get the caliper in on the wheel to get a more accurate measure but the length of the caliper and depth of the wheel would not allow that.
I have a shorter brass caliper that measured the nut at 36mm.
I dont know if the 2500 series would be a smaller size ?

I think mine were all the same other than some kits come with nuts and some of those nuts were smaller

36mm for the K2500/3500 across all years/models on the GMT-400 front CV axle nut. Also applies to the GMT-800 K2500/3500 series, too.
