Hello her “suffering” Well, I’ve had this “drive-wave problem” for a long time. Actually, most users here would have to be familiar with it for quite a long time. When starting or changing loads, you hear a “crack” or a “snarling”. This noise is often very difficult to recreate at the dealer’s office why it is often said “If you can reproduce the noise, you should come back”. I can reproduce the noise (know how I do it) and thought, because With you others who have not been around for so long, know what this noise has to do with it. This is how it sounds: http://www.youtube.com/watch?v=7FtWq2fLgLIWhen does it happen? The sound is heard as already said during load changes as well as more often while starting. It arises when there is too much play in the drive shaft gearing. Means: between drive shaft and transmission input shaft is more play in the gearing than in the tolerance ex works. e drive shafts before and back. What solution is there? The solution is simply but not really ideal. Volvo has official documents, which solves this problem. The documents indicate that the problem is known, why the tolerances are not changed is not clear to me, but rather repair. In doing so, the drive shaft is removed and with a special type of adhesive (m.E. it is a resin) which compensates the tolerances. By this measure (which is not very It can hold some 100,000 km, or even only a few 10,000 km. It depends on some points, but as a cost-effective repair (my workshop told me something of about 40€ for both sides – much time would not be needed) so pretty useful So, now you can, if you can not make the noise just take my video My dealer has confirmed the noise and my repair will probably be m July or August (currently I have too little time and then I have to follow the workshop ).
