It wabbles very much. I disassembled it, but I can't see anything. There is no broken pieces, no screw, so there isn't any discoverable thing inside of my Phatty. Day after day it hampered, and I don't understand, why.
Have anybody similar problem.? What can I do with it?
Through it the playing went very uncomfortable, when I use the wheel. But the Modulation wheel is ok, precise and stable...
What can I do???

The newer LP pitch and mod wheel assemblies have improved mechanics which eliminate slop issues. If I remember correctly, Moog is asking $50. for a new unit.
...Here are some quotes from Amos on the matter:
"Yes, there is a recent hardware revision, with an extra metal bracket to relieve tension on the pot shaft. I don't think it is possible to add this bracket to the original LP mod wheel assembly because the plastic frame around the wheels is modified as well. However, I will request some extra left-hand controller assemblies (this is the entire panel containing both wheels) and we can sell this assembly as a spare part. It would be easy to replace the old assembly with a new one. Contact techsupport (at) moogmusic dot com if you are interested.
Kind regards,
Amos"
"...In fact, anyone with opposable thumbs could fit a replacement LHC, as it involves only four screws and a ribbon cable and you don't even need to open the body of the synth.
Cost for a replacement LHC would be $49.
