- After painting my axles I noticed that the oil that was coming out of them was extremely dirty. This made me want to flush them, but as luck has it, these Volvo axles do not have a diff cover. I pulled the 3rd member off and soon I’ll probably be knees deep into a diff rebuild.

Thank you Robin. Good video.
Please remember, stay safe.
Great progress, Robin! I'll echo the others in that your pinion bearing, being a tapered roller bearing, wouldn't be held in place by anything once the flange is removed. I bet if you were to reach in and grab the other one it would come out as well, so that's nothing to worry about. However, new bearings are really cheap compared to the carnage they can cause if they fail while you're driving, so I'd definitely get a new set of bearings and races just for peace of mind. As long as you set the pinion preload correctly when you're reassembling, you should get many years of good service out of those diffs and axles.
The scratches in the pumpkins look like scoring from the manufacturing process so I wouldn't worry too much about that, and the small BB looks like leftover welding slag as others have said. Awesome build so far, keep it up!
The cone & rollers of a tapered roller bearing are usually not connected to the cup in any way, so they can just fall out like that after you removed the flange nut. But the play is a good indicator for a bearing that is done for or not the right amount of preload, so the bearing was either already dead or on its way out , like you said.
Glad that drop didn't destroy something and the progress is looking good!
edit: that small ball out of the front differential looks a lot like it's out of a ball bearing and has been mangled by the gears. although I'd expect all other bearings to be tapered roller bearings as well and not ball bearings, but I don't know anything about C303 diffs...
The commenter that said it looks like a welding pearl could also be right. As long as the gears all look fine, it doesn't matter anyway and you don't need to worry.
There are no ball bearings in the diff. I also checked with the manufacturer of the bearings and they also said the ball isn’t coming from them. I think it might be what the other guy recommended, a welding splatter. It also feels kinda porous. Thanks for all the info :)
Hey Robin, I do follow you at Instagram. No I could see the small "ball" more clearly. It seems to be a welding pearl. Have a closer look. The grinding is from production, after welding the housing together. Don't worry about.
Thank you for the info! Yea I think the ball is also from welding. Feels very porous as well & is to small to come out of a bearing
The scratches might be from the manufacturing process, are they on the top of the case also? The bearing that fell off the pinion shaft is just slid onto it and is tightened pretty much like a wheel bearing, if it is sloppy on the shaft or the bearing is worn check the pinion as well.
Thank you! I will do that. I suspected the bearing to be bad as it just fell out while I had to pry the one on the front diff off.
Scratches may have been caused by the vehicle being high centered on some big rocks and all the weight of vehicle was sitting on top of the dif with wheels off of the ground. When they were trying to get it back off the rock or log.Other than that there's no other way the scratches could have been made. Unless like u said Volvo did it.
Apparently they’re from grinding after they put the housing together. A few people suggested this and also other C303 owners confirmed, so that’s good to know :)
