As you can see i don't have the collet things and mine are nominally 10mm deep to the machined face of the spline ring and another mm to the inside of the casting. It makes me think that your ones were in the wrong box.

zukebob, do your bolts look like those in Lambert's photos?
I can't thank you and Lambert enough.

Do you have some transfer blue? If so put a little on the inside of the casting and fit and remove then you can see what is interfering in the hub assembly.

No I don't have transfer blue but, although maybe not clear from the photo, the grease marks and the slight markings on the inner rim indicate that it;s binding at that point. In fact I can see no reason for having the rim at all. Also the collets are a mystery - have they changed the design of the AVM457 to replace the perfectly good lock washers with the collets. I have no faith in them as they start to crack up at 20ft/lb +. The manufacturers are in Brazil and do not appear to be contactable, an engineering drawing of the part is the only way to resolve it. I'm tempted to return them and give up.

Lambert, you're a stud. I have to man-up now and finish pulling one of mine and see if I can understand the binding problem.
Kayjay: My fasteners are the same as yours, including the conical washers. My nephew is borrowing the Jimny to get his father back and forth to the hospital for a couple of days so I won't be able to pull the hub until then. As soon as I do, I will also measure mine, see if I can understand what your problem may be and get back to you.
Edit: Assuming you have the hub head off, measure the height of the vacuum seal from the hub head mounting surface. I will also compare that.

I have seen these collets, coned insert, before. Used on some hubs i once dismantled from an SJ i think. I do not remember what brand those where. They should be just fine as long the hole you put them into is coned as well. And it looks like it on your pictures.
If the bolt holes are coned you must use them and should not replace them with ordinary washers.
It is possible to use SJ hubs on a jimny if you use spacers. Spacers for this can even be bought and will make more space where these seem to interfere on your car. Most likely you have SJ hubs there as all other measurements are the same.
This could just be a production or marking error in the factory.
Your supplier should replace them.
edit: I can measure my SJ hubs later today to see if they have 12mm inside to the interference spot, the same as yours.

yakuza, The bolt holes on mine are coned but the collets seem to start failing at around 20ft/lbs +. They just don't seem up to the job, although yours are OK. I wonder if I could replace them with flat+spring washer combos. My supplier to be fair say that they are not engineers and they could only replace them with another that on the face of it would be the same.

The cone washer things are called 'cone washers'. Any good engineering supplies place will be able to provide them. They are not usually made for high torque, so the 20ft/lbs is probably about correct. Having them in and out a few times wouldn't help.
I agree with Yakuza that it sounds like you have been sent ones for an SJ or a vitara, which means spacers would be needed to use those hubs.
Your supplier may be able to measure the replacements they have in stock to see if they are the same as your problem one?

The supplied manual says "tighten to the specifications of the vehicle's manufacturer" which is 35ft/lbs
I googled 'cone washers' and nothing similar came up
