Change to the old style hub nuts?

Hmm... seems on further reading that a few have done this, and is suggested in this thread here

Anyone got any thoughts on this? I like the idea of being able to disassemble/ inspect/ repair in the bush a little more easily.

Just closing this out... I capitulated and bought a 52mm deep socket (and a torque wrench)

... it turns out that 210Nm, and the staked nut design, ain't so bad when you have decent tools. Lesson learned.

The draw back of the staked nut is in my opinion twofold

If you don’t remove the folded over tang adequately - the process of undoing said but Rogers the thread form

Secondly, although you may be able to re-use a stake nut - eventually you won’t be able to secure it in place once all nearby flange is folded and broken away from the machines locking groove.


Having said that - the spacer and high torque technique for a pair of tapered bearings gives a more consistent pre-load than other methods ....

For what it is worth I recently changed over my tdci to old style lock nuts

I also changed to old-style paired nuts and lock tabs. There is another drawback to the single staked nut and spacer- the spacer is specific to those particular bearings in their brand new condition. It does not enable adjustment of preload when reassembling worn bearings nor when replacing bearings. I believe it is simply a manufacturing shortcut that removes the requirement for skill from the assembly process; just bang it all together and rattle it up with a big rattle gun set to hellish tight.

I have the spacer, and paired nuts and tab. Best of both worlds?

Correct spacer as per shop procedure with proper gauge etc, and the inner nut done up to same torque as stake nut spec.

I'm no expert, but my logic (which I tested with Ian at MTE4x4 Morwell prior to closure) is this would allow me to re-use the nuts and spacer is just re-greasing existing bearings, but if an unplanned bearing change was required, to remove spacer (as I don't have a gauge) and return to the usual method of setting pre-load.

Be great to hear others thoughts on this approach.

It’s the same as gearbox rebuilds
Variable spacers are NOT in play for variance in bearing dimensions
They are used for variance In casting and machining variance

Same bearing number from three different manufactures including whoflungdunglast200km rubbish will be within microns

That UN-CNC machined stub axle you have will lie somewhere in the range of acceptable deemed by LR in 19dickety two which was +2metres - 0.765miles

Spacers take up variance in variable tolerance

For all intents and purposes bearings and Shells have zero tolerance


The only reason i wouldn’t use the spacer AND dual nuts is how do you work your “mojo” when you can just crank her home ???

An interesting discussion, and, armed with a little more experience and knowledge than a couple of days ago, I decided to stick with the staked nut design...

A sharp chisel bent/cut the flange back out of harms way, its pretty thin/ soft.

Other than in an emergency, re-using these (mangled) nuts is out of the question surely? They're very cheap.

Thats the thing... I see this is a significant advantage (to Land Rover, the average mechanic (me), and therefore to owners (also me), and worth putting up with the minor disadvantages - that the vehicle Engineer (and not the mechanic/ user etc) , via this arrangement, controls the bearing pre-loads.

Set and forget
