Re: HUB Separating from Axle
OK Guys,
I have bee gathering information about this (design fault I will now call it) and talked to my mechanic about it as well.
When I told my mechanic what has happened to Craig and others, he said that is very strange and shouldn't have happened at all, but he didn't rule out a foul play by whoever serviced the hub last. He also was very surprised to hear about the need to use locktite in that area and never seen a hub nut held in place by locktite!
When he asked me if our hub nut was lockable, meaning the locking pin going straight through it, I said, nope, the pin sits away from the hub nut and there is about 2-3 treads where it can come loose.
As soon as I said that, the mechanic stated that it is a design fault indeed and it is not the way it's done on other cars where the hub nut is secured by either of the following methods:
1. Hub nut having a hole in it for the locking pin to go through when it is tightened in place.
2. Hub nut having a locking crown covering it which has grooves for the locking pin to go through to ensure the nut doesn't get loose.
We have talked about ways of fixing this problem and he suggested that we make something up where we could fill the gap between our hub nut and the locking pin, so we could put a crown on it.
One of the options was to fit another nut on top of the existing one and then have the crown on the second nut and the locking pin going through the crown.
We will be exploring this possibility soon and see what we could come up with.

Is the space enough to have a spring washer or two flat washers under the existing nut to have it tighten so that the edge of the existing nut finishes flush with the pin hole ?
Or would a nyloc nut be just that little bit bigger with its top rim so that there would be no gap between it and the pin ?
My preference would be the nyloc nut and have it replaced when the bearings are replaced.

Re: HUB Separating from Axle
OK Guys,
Today I had my rear pads replaced and the discs machined, so I had a closer look at this Design Fault
There are 4-5 treads between the edge of the hub nut and the locking pin that would fit another nut, but it is far too wide for any sort of spring washer to raise the existing hub nut.
My mechanic was astonished when he saw how far the locking pin was from the hub nut and suggested that I have this hub nut completely changed with another one that comes already with the locking crown and would reach the existing locking pin.
He gave me the details of a local manufacturer that has these hub nuts and I will soon go there and see what they have on offer.
In addition to this design fault, the hub nuts and the locking pins on my exy all looked rusty as hell, which made me worry about them even more!
P.S. None of them were loose.

Re: HUB Separating from Axle
Yes Roman, applies to all four wheels and all exy models.

Re: HUB Separating from Axle
Hey Roman, you should have told the service manager to have a look in our forum to change his 20 yrs view on this 
The argument is not about the way it has been engineered, rather the way it has been incorrectly designed and the guy at Nissan should have asked himself that question when compared to other newer cars on the road which don't have this point of potential failure.
