For the ten years I have owned the E3 there has been a distinct "shake" in the drivetrain when taking up drive (manual transmission). I always thought it was either the Guibo or centre bearing although inspection of these has never revealed any obvious faults. Also present was a chattering from the transmission at idle that could be stopped by just lightly touching the clutch pedal. Anyway, the box has been removed to reveal a significant amount of lateral play in the input shaft. This would explain the above issues perfectly. Having only just discovered this, I have yet to do any research however I'm sure there are lots on here who can advise. Is this a major job to repair, indeed can it actually be repaired with bearing replacement or is it likely to need a complete overhaul given that it has been "shaking" for at least ten years. I have to add that despite this issue the transmission has been faultless at all other times so I don't think that this has caused any other issues within the box (hopefully).
