Gee, that's tight! - rear axle stake nut.

[Leo109]

Hi All,

Started a long overdue replacement of the LH rear hub today - until I got to undo the stake nut. 500 mm breaker bar with my full, not-inconsiderable weight standing on the end made no impression on it. Nor does a 600 mm length of water pipe on a sliding tee-handle (except for starting to bend the tee-handle bar).

So most knowledgeable ones, how do mere mortals shift these things please? Will a rattle gun move it? (Neighbour has one, but is away today.) Really don't want to put it back together with the greasy old undersized disc and worn-out pads to take it somewhere if it can be avoided. Thanks.

I undone the front one by jacking the car up as far as i could go,put the breaker bar on a car stand and let the jack down,All done from behind a brick wall in case something gave way.Perhaps you could hire a torque multiplier from somewere.

There is a neat, even if I say so myself, wheel nut torque spreadsheet.

100kgs at 500mm is 490Nm of torque. If you are more than 100kgs then it should undo. The torque for the hub nuts is 490Nm.

if its the stake nut version...

unstake it first.

I just use my milwaukee gun does 1400nm nut busting torque

Combine this with Dave's post just prior. But I reckon my 3/4" Milwaukee would do the unstalking for me. Thing is nuts...

Aren’t they brilliant.

Bought a lot of tools in my time, Mike, but, as a bald Irish woman would tell us, Nothing Compares.

Yes, that's what I thought too. But my not-so-svelte 105 kg didn't budge it...

Yes, definitely unstaked! It's not a left-hand thread on the LH side, is it?

In any case, I've tee-ed up with the local tyre place to rattle it loose on Friday arvo, then nip it up tight enough for me to drive the 600 m home to have another go at the job this weekend.

Yes, tried lowering the jack with the breaker bar on a block of wood. Was as much force on the breaker bar as I dared to use (without a handy brick wall in the middle of the garage), but no movement from the nut.

Where are you? What size is the nut?

Did you try a bit of bouncing?

[Blknight.aus]

break out force almost always exceeds torquing force.

also yes the milwalkee will undo the staking for you, it will also in the process if your luck follows some hapless fool who then needed me to replace a stub axle, remove the thread of the stub shaft.

This is, of course, possible. But maybe that will be the result here anyway. The OP says he has already undone the staking, so there seems to be more afoot.

not really, I've maxxed out 1000nm torque wrenches trying to undo the stakenut setup and wound up with the only solution being the 3/4 drive rattler or the 3/4 breaker with the bar torque mulitplying and a hit on the crown of the breaker with the FBH.

Heat? Not too much. Might just loosen it enough to be removed.

Cost. Plain and simple.
