Front axle nut 98 K3500.. size?

[Yesterday]

Anyone know the size of the front axle nut on a K3500? Need to replace the
rotors. Looked in GM manual, can't find the size.

It's a unique self-locking nut, and you'll have to order it through a dealer or parts house by application. I don't know the thread size (I did, but don't now), but the hex is 36mm and torqued to 177 ft/lb for your application . GM (manual) requires replacement after removal. However, I have reused them in a pinch (unavailable or inconvenient at the time). I use Loc-Tite on them, if reused (not new).

Why are you removing the axle nut for a brake rotor replacement?

[joed]

On the 3/4 & 1 tons, unfortunately (at least in terms of service ease) the rotor and hub mount as one unit.

The whole assembly (hub & rotor) has to be removed and the lug nut studs have to be removed before the rotor can be separated from the hub.

Fun!

Ok, thanks

Guess I'll have to order a couple of nuts.

Hate those one time only setups.:(
