Wheel nuts too wide

[wouldbeowner]

Recently had a blue slip inspection and was pinged for the wheel nuts being too wide. They probably extend beyond the end of the stud by about 2mm. The car has wolf wheels. Is this unusual? Has anyone else bumped into this issue - how did you address it. I suppose I could take them to a mechanical workshop and get them ground down.

Interesting fault to get you on - all Series Landrovers up until the very last of those with 9/16 wheel studs (1948-1970) had the nut extend beyond the end of the stud by a couple of threads - I always assumed this was deliberate, to prevent damage to the thread of the stud.

The Wolf wheels are thicker than the standard wheels, so this is not unexpected.

Hi wouldbeowner

A picture in this case would be worth a thousand and one words, as a little more info is required.

There is a large number of thread types and sizes used on Land rovers over the time, so there would be a nut size and type that would fix the problem. I think that grinding the nut to suit would be the wrong way to rectify the problem.

The early reversible nuts, were actually proud of the stud by about that much from the factory, therefore if that is the case with your vehicle, whoever inspected it would have egg on their face .

Even brand new Defenders with the bigger steel wheels have the same nut/stud appearance.
Would a picture of one help your cause?

You can change your wheel studs to the longer ones (e.g. Britpart part No: FRC7577) by banging out the old ones and putting in longer ones. Apparently you can do this with the hubs still on the car.

Or, you could put on the standard rims to get through the blue slip, and then go back to the wolfs.....

Pretty bad luck to get pinged for that though

sounds like the blueslipper tried hard to get you on something - AFAIK all 110s (& 109s ?) have wheel nuts that extend minimally beyond the stud as standard - as JD says it protects the threads

better see a competent blueslipper, preferably one who knows LRs

Like this - I presume?

I had the longer studs fitted after getting wolf rims. I think early 110 wheel studs might be a few mm longer than defender ones as thread was showing less on the county front axle compared to my defender disc brake rear axle.

Yes, exactly like that. The Blueslipper pointed out that the wheel nutes probably were like that from new and he realised that it seemed harsh but, as he pointed out, the criteria he is reqd to test on are written and in this case the wheel nuts dont comply with the written reqts.
Is anyone who reads this familiar with Blue Slip inspections at a professional level?
If so, does the fact that an original, and at that stage legal, design feature is now proscribed by NSW RTA regulations mean that it is now failed in an inspection?

[dullbird]

I dont think they can fail it if the car was around before those regs were bought in...if that was the case anyone getting an early series blue slipped would fail for not having complaint seat belts..

I would also be calling him and asking him which section of the ADR's he has failed it under so you can look it up yourself
