      This is a little off-topic. But I’m curious… How much would a re-balance of the drive shaft cost in the US? Here it would in my case cost about $650 (brand new cost $560) to get my drive shaft re-balanced. I’ve spoken with other people, and the highest cost I’ve heard is about $1700 for a re-balance. There is only one company that does balancing like this in Norway, so shipping costs are not included, but would be about $43 I think.

        Got a phone call today from the workshop. The new drive shaft were not complete, and a few other parts had to be ordered. They just wanted to let me know of the costs and my options. Since most of the parts have arrived already, I told them to get the rest. I’m tired of used parts which can’t be trusted, that’s why I buy everything new. With the extra parts it will be a little bit more expensive now than to re-balance my current drive shaft.

            The differential looked something like this when I took off the lid:

            Absolutely hideous to drive with, and not to mention illegal. I changed out the differential with one gone about 160.000km, and had the rear axle checked for any slack or bad bearings. Had the rear axle at the Volvo dealer in the summer, and found to be well within specifications. I didn’t change the axles going to the wheels from the differential (as they were not damaged from the welding). This is a solid rear axle, so they are on the inside. I were told later that these have a tendency to get deformed because of the unnatural stress inflicted from the 100% locked axle.

                Spoke with the workshop today. They tried the summer wheels, with no luck. They replaced the axles inside the rear axle, without luck. Their conclusion is that the problem is the drive shaft it self. They’ve now ordered a brand new one since it were more expensive to rebalance the one I have. Hopefully it will arrive in a few days time.

                    I delivered my car to the local Volvo dealer for checking. They found out that one of the rear wheels where not in balance when rotated. I have now given them my summer wheel set to check if the problem persists. I also delivered a new set of axels for the rear axle, as they might be deformed. The differential have been welded on this car, so it might be a possibility. If this still does not fix the issue, they’re going to send the drive shaft away for balancing. They don’t know where to do this as the local shops are out of business now.

                    I were also told by the mechanic that there will always be some vibrations in rear wheel driven cars. The drive shaft will always shake a little bit. This sounds a bit odd to me.

                        Had a word with the Volvo dealer today. I were told it is a pain to get that fixed since it is much trail and error involved. Costs and time could not be guaranteed. They have time to look into it in January, hopefully they’ll get it fixed. I’ve done much of the work already, so anything now would be to measure angles or get the driveshaft balanced I think.

                        The vibrations are probably not healthy for the bearings in the gearbox nor the rear axle?

                            I spoke with the local Volvo dealer a couple of weeks ago, but they were hesitant to take the job. They have another customer with a Volvo 960 that also have vibration issues, that they haven’t been able to fix. They also told me that those who work there are young and not experienced with older Volvo cars.

                                I read through that link, but it did not say anything I haven’t tried. I have no tools to measure the precise angles for the rear axle pinion. Nor do any workshop have tools for this. I guess the only thing I can do is to fiddle with the driveshaft and try it spline for spline. Very annoying that the workshop had to mess that part up. I don’t know if it exist any workshop that can balance driveshafts either, none I’ve spoken with can do this.

                                I know that the holes for the bolts in the rear end of the driveshaft/rear axle are offset, so that it can be assembled only one way there.

                                I could also mention that the previous owner had welded together the differential. This were, as mentioned, replaced and checked. Might the axles inside the rear axle be warped a little bit as a result of the welded differential? If they at all are long enough to cause vibrations.
