At my DTI there is the latest effect : from approx. 100 km/h to approx. 120 km/h it is now also buzzing with my omi from the HA, but only as soon as I walk from the gas, i.e. in sliding operation, while in train operation it decreases, or is not audible anymore. Of course I used the SuFu and stayed stuck with the following statements : wheel bearings, differential, sliding part and support bearing cardan shaft… Tires were also there wheel bearings I exclude, since these still relatively fresh si nd, AND because the wheel bearings typical sympthome do not occur tires I also exclude, since changing the tires (on the new WR) does not bring any effect EDIT : elephant feet etc. I can actually also exclude because new, as well as hardy disks etc. To my misfortune now I do not know very well with the rear drive (screwed before the omis only front milling), therefore sliding piece and support bearing cardan shaft and differential can be considered… WHO can Now give me just technical advice here, and explain how I can check the above components ? What makes me the least worried about screwing up and inspecting the diff, except that I don’t know which, and how much oil has to be refilled (because I haven’t searched yet ) Other tips ? Thx in advance !
