I prefer the old two nut style and that's what I have on my TD5. It's what I've grown up with on my Land Rovers and Toyotas.
The thing I like is if I notice a wheel bearing needs adjusting I don't need to order any shims or keep any stored away I can just whip the drive flange off and tighten as required. No faff. |

When I replaced my wheel bearings this year I converted to the two nut system

I have a parody on mine. When I bought mine I also received the full workshop history from its previous owner, Thames Valley Police and apart from a few wheel bearing adjustments there was no mention of a bearing replacement. The parody is that the nearside has the single nut minus the spacer so just acts like a traditional wheel bearing set up and the offside has the two nut arrangement as do both the rears. The peculiarity is that the bearing that gives me the most need for maintenance is the one with the two nut set up.

I wouldn't take a sound bearing set apart simply to change from the one-nut to the two-nut system, but would always convert to two-nut if any maintenance is needed.
There are no disadvantages whatsoever to the two-nut system, and several advantages. |

Land rover changed it to the latest system for a reason ...
Two nut system was fine, but honestly, once set correctly a bearing doesn't need 'play' adjustment .. the play is telling you It needs replacing! Stick with how it is .... Guns and Landrovers .... anything else is irrelevant. |

I suspect the reason was to de-skill the assembly process and reduce production costs. It is hard to see any other reason.
In a world where you have virtually unlimited access to different sized spacers it may make sense. |

If you do not do a lot of off road or expedition driving stick with the stock one nut setup. It is the simplest and it works fine, no loose bearing to readjust just put in a new set... 2010 Range Rover MkIII Autobiography Super Charged (Idris)

Single nut systen only done as cost cutting exersize. Less parts and quicker to instal. Impossible to adjust if you're in the middle of nowhere.

That was the whole point of the single nut upgrade Yetiman ... nothing to do with cost cutting, It's a more reliable system.
Wheel bearings can't loosen [as often happened with old system] and need re adjusting. Play in latest set up means bearing is worn and needs replacing ... Guns and Landrovers .... anything else is irrelevant. |

All bearings wear, but just because they have slight wear doesn't mean they're knackered and need replacing which is where the old system is superior because the wear can be adjusted out easily. Everyone has there own opinion but it seems the majority of people and all the people I've known through various clubs and organisations prefer the old method.

The single nut system makes sense for initial assembly and is consistent with the modern 'sealed-for-life' ethos, and lifetime dealer servicing. It makes little sense in any other situation.
It is a nuisance if you have to change the wheel-bearings since the chance of the original spacer being correct for the new bearings is small, so unless you have a selection to hand it can be difficult. There is a small risk of damaging the threads on the stub-axle when removing the stake nut. You're also likely to need a bigger wrench than for the 2 nut system.
I'm not sure at all what the basis of this suggestion. In 40 years of driving and working with Series and Defender vehicles I have never heard of a properly-adjusted two-nut wheel-bearing coming loose, and I cannot accept that it is a common occurrence. Bottom line is that either system works and is satisfactory, it is up to the owner to make up their own mind. Assemble either system correctly (and neither is difficult) and you'll have no trouble. If you're not confident that you can set either up correctly then get someone who is competent to help. |

I bow to your 40 years experience, I've only been doing It as my main employment for the last 27 years
Only messing  We get a fair few on the earlier set up where owner has 'adjusted play' and within a week or two they have either come loose again or seized up owing to said owner not having required skill level ....
Never have a problem with later one nut set up .. if unacceptable play is detected, just stick in a new pair of bearings and fully tighten nut - job sorted. For the record, It's also [In my/our experience] very rare to need to replace shim, current tolerances are so close that the original is almost always correct [As long as not using cheap chinese bearings lol] Your right, everyone has their own preference and ideas ... for me It's the one nut set up rules Guns and Landrovers .... anything else is irrelevant. |

I did qualify my comment with the words "properly adjusted"!
