Re: HUB Separating from Axle
Hello!
Seems like most of you have let a garage/dealer fix your Wheel Bearing problems.
Anyway, when I bought my X-Trail it had done 90 000km.
The previous owner said that the right side wheel bearing was changed once. And that
he had noticed something from the left side when towing his caravan lately.
Whe bargained on a deal, excluding cost of wheel bearing change and so on and so fort.
I didn't really notice anything with the left front wheel bearing myself, so didn't do anything
about it just yet. As time went, it suddenly made noise.
And with somewhat gentle noise for about a week and a half, it became a lot worse.
I bought wheel bearing and a hub from my Nissan dealer and went on with the repairs
myself.
After I had pressed the Hub out from the Knuckle, and gotten the inner race closest
to the wheel side of the hub off the Hub itself, I took a vernier micrometer and checked the
size of the Hub part.
The Wheel side of the Hub was 43,52mm, and the opposite side was 43,46mm
When it comes to bearings, this is a fatal diffrence.
I checked over the wheel bearing, trying to turn it, thinking it had seized and then spun
the inner race. The wheel bearing felt like a brand new bearing. It didn't turn
without effort like a used bearing. It had the resistance a brand new bearing has.
I tryed on both the inner races. And both of them were loose on the outer part of the
Hub, and both where Thight on the inner part of the Hub.
The New Hub was Ø43,52 all over. The bearing was tight, and I pressed everything
togheter with about 4 tons of pressure, as the FSM states.
The nut have come loose once after this, but after a thigthening it is all good.
This was around 98-100 000km.
Now it has gone 120 000 +km.
And of course the right side have startetd to act up. I'm doing that side myself as well.
Getting the parts for it monday. Picking up both the bearing and hub incase it is
suffering the same thing.
Both the Rear's have also been loose on the stubaxle nuts. I'm changing them with some
used Complete knuckles from a 2004 model. Better then nothing I guess.
My conclusion is that maybe the hub or the bearing have been a bad batch.
Like only 1 of the 2 inner races might have held the hole weight of the car.
When the 1 side of the bearing finally starts to wear enough for the second Race
to come in contact with the hub, there is so much play that something grinds.
I still have the parts from the first job. And had a look at them again now that the other
side started to act up.
Can't get my head around how the hub is smaller on one half when the bearing is
in mint condition. If the bearing had seized or had some faulty balls or the likes, I
would have settled with weak design.
Anyone with anymore input feel free to chime in.

Nice to see that I'm not the only one that likes doing things like this and getting dirty. Mind you not on my T31 yet.
That is a big discrepancy between both sides.
Was it the type with a hub nut and lock washer?
The first time you tackle anything like bearing replacement is a bit daunting, but when you do it you can't justify spending hundreds of dollars at the mechanics for what really is a 1-1.5hr hour job each side.

Re: HUB Separating from Axle
Just finished replacing the hub and bearing assembly on the front right side.
The story is the same here. Though the hub was a little more scorched by the bearing
on this side, it was the same with the bearing.
The bearing runs free and seems to be in mint condition, but still it is completely loose
on the outer part of the hub.
The side of the bearing I presume is knackered, came apart just like the first one,
so I can't really tell how bad it was.
It did notice some play in that side of the bearing when I checked it after taking the
knuckle off the car. I guess that side was pretty worn anyways.
Still makes me belive that the bearing only supports the car on 1 of the inner races,
and not evenly on both because of a production mishap on the size.
The new parts were just like the first ones I replaced.
The bearing is about 2 hundred of a mm smaller then the hub. Both inner races were
the same, and the hole hub shaft was also the same.
The Hub were 43,51mm, and the bearing inner race were 43,49.
Either there were some dirt on the hub first time I checked it, or I just remembered wrong
when I wrote down 43,52.
