My 4630 wanders also. It is an early model that has steering hydraulics similar to a 20 series, the later 30 series had different steering hydraulics that was used on the 40 series. Last year the dealer went through the steering valve (it was leaking anyway), but it didn't help the wander. It will be going in for a rebuild on the steering cylinder before spring, and I hope that fixes the problem.
