A bit more info would be helpful. On your build plate where it says "axle" it should have some sort of code eg g242. If you could post that, that would be helpful. Most 4wd hilux's have do have an LSD, but as for bearings, you'll have to find out when you pull it apart. If your fitting a lockrtie, then this won't matter anyway (pinions, lsd etc) as you throw those away. Cheers
