I will start by posting a video illustrating the issue: Track issue
To put the issue in words; the tracks will randomly jitter along their respective axis. This is not limited to the one area shown in the video but also occurs when the track runs along the top of the roadwheels. I may be wrong but I think that this may be due to some sort of instant change in acceleration which happens to one track; resulting in a chain reaction. The rotation and scale of every object is applied. If anyone has insight on what I could do to mitigate this issue I would greatly appreciate it.
Rig details vvv
The drive wheel has a motor constraint along with a the generic spring constraint (which does not have springs enabled) and the tensioning wheel towards the front is the same as the drive wheel minus the motor constraint.
Here is a file which contains the rig. One side of tracks is a different size from the other as I was messing around trying to find solutions (It doesnt effect anything).
