View attachment 8There have been discussions on driveshaft (propshaft) vibrations etc, but I want to focus specifically on the "Compensating plate"
On real OEM for my car I find this Compensating plate (BMW P/N 26121229539). It looks like a washer and if I understand the description correctly it is 2mm thick (H=2MM) and it seems to sit between the center bearing mounting and the chassis, ie it is a spacer of 2mm thickness. Which means it could be "compensating" for an angle misalignment ? (I think compensating plate is like calling a nail a steel dowel).
The reason behind this question is that I have had a long standing vibration issue AFTER my car went for a torque converter job. The original people never got it sorted so I went elsewhere where they managed to improve the matter to where it is livable, but not the silky smooth car I dropped off before any work was done. The question has always been "what changed" when the work was done ?
I have browsed many global forums on this topic and there have been speculation about spacers and emphatic denials that such spacers exist (Apparently Bentley manual refers to spacers). So what is the truth ? And what is this "compensating plate" and exactly where does it go ?
If it is a simple spacer then it seems very likely that the first guys undid bolts, dropped stuff to the floor and lost the "washers" (compensating plates) that fell off. So after assembly there was this possible misalignment and hence vibration issues - imagine my joy if it were that simple and frustration at the money I have wasted in an attempt at getting it resolved.
Anyone have any thoughts in this regard ?
