I just got a phone call from the workshop. A mechanic have looked at it now and insist that there is nothing wrong with the differential. He claims that the oil is black because of some additives. I asked if they have measured the backlash and other clearances with a micrometer gauge, but I were told that wasn’t necessary. The mechanical parts isn’t that precise.
I’m a bit unsure now. Everything points to the rear axle, the differential. I hear clunking noises, bearing noises, feel slight vibrations and I almost burn my hand when touching the differential housing after a short drive. Something is clearly wrong, but the mechanic insist it is absolutely fine. Looks like I’ll have to start searching for a used rear axle…
The paint job have been dragged out quite a bit, unfortunately. I haven’t forgotten about this thread! I’ve been promised to get the car back this week. I spoke with the workshop last week, and they’re going to take in my car and look at the differential next Monday (29th). Hopefully I’ll get some answers and hopefully a solution to this annoying issue shortly after. I’m still a bit unsure what I can demand in this situation. Some people have told me to just let it go and just buy a second hand axle with working differential. Hopefully I won’t need to look for another second hand axle. I reckon it will be quite difficult to find another one with low mileage, correct speedometer gear/sensor and the correct gear ratio.

The car have been at the paint shop for a couple of weeks now. Not long until it is done, so I’m going to contact the workshop to get the rear axle fixed as soon as possible after the paint job.
I’m a bit uncertain what I can demand in this situation? This have cost me a lot of hours and money to troubleshoot. I want the differential to be at least as good as one driven 160,000km (about 99,400 miles). That were the condition of it before I handed it in for checking last summer. At least the pinion bearing needs to be replaced besides adjusting everything properly. I would guess the other bearings too would be recommended to replace because of the bad oil? It probably didn’t have the proper viscosity anymore and had debris in it. I’m also concerned about the gears. Would these also need replacing to be at least as good as 160,000km? I don’t want to drive around with anything that could break because of metal fatigue as a result of one year with bad oil/adjustment.

I went and spoke with the workshop that checked the rear axle last summer. I got a hold of the person that I dealt with then. I explained what I found when I opened the differential and showed some pictures of the gears and the oil. He looked quite shocked when he saw the oil. I were told that there is no other option than that they take in the car to look at it again. They also wanted the oil that I drained off to take some samples. We agreed that I’ll contact them again when I have time, and not drive the car more than I have to.
I’m going to get the underside treated for rust next week and repaint the car at the start of June. Luckily I still have my Skoda that I can drive. Not as much fun, but it will have to do.
Funny that the one thing that were supposed to be guaranteed to be fully functional and well within specifications turned out to be the cause for all the trouble. I’ll update later this summer when the workshop have looked into the issue.

I came back from work now which is about half an hour drive. I jacked up the car a little to crawl under and feel on the differential. I first put my hand on the cover which was lukewarm, and it got hotter the further back i felt towards where the drive shaft connects. It wasn’t so hot that I burned my hand, but it was quite hot.
This would suggest a broken bearing?

I probably should go and have another chat with the workshop then. After the repair/replacement I changed all the bushings and meanwhile sent the axle to the dealer workshop to get everything checked out. This issue should have been corrected by the workshop. I did pay them around $400 which is equivalent to about a couple of hours pay. I have had some poor experience with them afterwards, so I suspect the mechanic have not done anything and just billed me for a couple of hours.
Would this be dangerous to drive with in any way? Could the wheels lock up if it fails completely? Not sure if I should park the car and drive another car until I can get this repaired.

So it is not set up right. Can this happen all by it self, or is this from when it were replaced? If this is from when the welded gears was replaced, then I can assume the workshop have not done their job right?

No suggestions? I remember when I brought back the rear axle after I had it at the Volvo workshop I were told that they had not filled oil back into it. I therefore got a couple of cans to fill it up with. When I were going to fill it up afterwards it already had oil in it. I didn’t think much of it then, probably just a simple misunderstanding. Now I’m quite unsure if they have actually measured the clearances, torqued it, replaced shims etc.
The only reason I haven’t checked the rear axle yet when troubleshooting is because it were supposed to be 100% okay.
If it is not the workshop that have done a poor job, then what causes wear on the gears, slack and noises? As mentioned earlier, the unit were driven 160000 km (about 99400 miles) when it were put in. I would expect something like this if it were driven 4 times the length, but not under 200000km.
I’m unsure if this is something I should complain about and demand to get repaired. When I showed them the oil I were told to drive it for a month and drain the oil again. It could be a broken bearing they said, but most likely just crud that haven’t been cleaned out properly. It didn’t vibrate much, so they would not worry about it.
I know that the oil were changed in late october, and once before that just before the summer. The oil did not have any unusual discoloring then, except in october when it contained small metal particles.No suggestions?
