Driveshaft disengaging on FS2

[/tobys]

Ran FS2 yesterday (until it got too wet) and it was great in practice.

However, I noticed after R1 (which I only 1/2 completed due to shoddy tyre gluing LOL) that the front centre driveshaft had become disengaged from the plastic drive cup.

Looking at it, there is quite a bit of movement possible there and unlike the rear, there is no method for adjustment. To reduce the available movement, I was planning to put a small piece of fuel pipe into the drive cup.

Anyone else had this problem and/or see any issues with my solution?
