Drive axle Hub Nut size

Anyone know what size the drive axle hub nut is? I need to replace the bearing assy and would like to get the right size axle nut socket.

94 Lumina Z34
3.4 L DOHC

38mm I believe

36mm (did both my fronts not too long ago...)

thanks .
projects for this weekend

Timing belt replacement
Power steering return line replacement (of course it's behind the motor)
Front wheel hub assy
Replace crankshaft oil seal

All tips welcome

It never ends!

Happy New Year!

oops sorry I always get that mixed up

Put transmission in neutral then take off front motor mounts and you can rotate engine forward to allow room in back to work

There are 3 mounts right? 1 upper, 2 at the timing chain end and one at the transaxle end. So which ones do I remove (I know about the upper one) and which ones do I loosen?

You have a 3.4. Don't bother removing your mounts in the fleeting hope that you engine will tip forward. It won't. :disappoin Only the 3.1's were afforded that luxury.

I think I have finally figured that out.
Thanks
