My sister in law's Frontera (LWB diesel, L-reg) has an odd problem - when in 2WD mode, it tracks perfectly. But in 4WD, it pulls to the left, by quite a significant amount. Switch back to 2WD, and it goes straight again.
Any ideas? If it was suspension or steering related, I'd expect it to show up no matter whether it's in 4WD or 2WD, but it only exhibits the problem when in 4WD. Diff? Hubs?
