That would explain why you car self centers when reversing. Best to give tt a nudge and see if there is anything else odd about the 4x4 hub.

The lack of caster has been a known fault right from the original design, and I believe has been a problem on the MK as well yet there is still no revision to the design, update of the book in this respect. Unfortunatly most builders don't find this out until they've built the chassis/car so end up having to 'bodge' around the problem.
A solution if you can get them would appear to be the 4x4 upright,but it would be better for a sticky on here relating to this design problem so future builders have the chance to 'build in' some extra castor.
