The FL2 always starts off in 4 wheel drive up until about 19mph.

I don't think it is Haldex.

I take it then, if I did lift the entire vehicle off the road, and started it up and popped it into first gear, then all 4 wheels should turn in the air at the same speed? |

I had a shot NSR wheel bearing - no play on the wheel whatsoever and the noise sounded for all the world as if it was centre rear… Convinced the diff nose bearing was failing based on those two things… Booked the car into Bell’s for diff repair/replace but Austen (Bell’s) diagnosed NSR wheel bearing - even said he'd pay the cost of the bearing replacement if he was wrong - he was right. Wheel bearing replaced, problem gone. Cheap fix to what I imagined was going to be an expensive job. |

I seem to remember a test for rear wheel bearing wear is to drive down a straight safe road at about 20-25 mph and steer left to right to bring any noise out by wobbling the bearing under load. Anyone tried this. |

Like Reggie, I have a drone that I was convinced was an expensive fix (front in my case, so was wondering if the new IRD had failed).

Pretty much how mine was diagnosed. A little faster perhaps with some fairly decisive steering inputs to shift the wheel loading from side to side. Apparently, wheel play is not an early indicator of failure in progress with these bearings. |
