Re:I managed to crack the ABS ring! :)

After the 3rd oil seal failure I did check my pushfit breather and it works fine.

But I don't know how to check if an axle housing or axle shaft is bent.
The repair manual says nothing about these things (or I just could not find it)

I've seen a video before, where the guy measured the distance between the brake disks around their perimeters. In teory you should get equal distances which means the disks are parallel. But that's not gonna work for those who still have drum brakes. And I don't know how much difference could be acceptable if any?

I guess a dial gauge could be used somehow but maybe this investigation does not require that precision. I don't know...
What I do know is that a front bearing is twice as thick than a rear one for some reason therefore full float axles the way to go in my opinion.

Yes, a fully floating axle is the best option as it removes the need for the shaft to absorb bending stresses whilst also removing any tendency for the brake disc to float in and out.
The first step to check for axle tube distortion is to check for visible signs, ie cracked paintwork or obvious ripples in the steel. Does the diff. to casing joint leak oil? If so this could indicate warping in the case. The best method is to remove the axle, remove the paint and then a more diligent check for obvious damage. If you mount uprights on each end of the case you can take measurements at two points and compare. Obviously the longer the uprights the greater the accuracy. To check the shafts you need to mount them in a homemade jig and spin them. It might sound crude but bits of available wood and a wood screw to adjust might be all you need.

Hi,

We have checked now, there is no play in the newly installed bearing (of course), so it did not fail during this short use. We have checked now the factory breather, removed the cap from it, it was a bit seized, was not moving. The breather pipe shows inside open. Replaced the cap on it, now it is surely not blocking the pipe so pressure should not build up. Will run the jimny longer during the weekend and see if the leaking continues.

There were no signs, or suspicion that the shaft, or the complete axle was bent, or damaged. And also, it never received serios abuse. Due to excessive play in the diff itself, it was removed and had it overhauled. During removal and after installation there were no signs or suspicion on gamage of the axle housing either.

And the problem this time went from the earlier left side, to the right side now.
