Thread: D3 - Transfer Case Noise (Whine)

**Correction - It was the center bearing on the rear drive shaft that was replaced.

The 4WD is going to another LR specailist today so I'll let you know the outcome of what they think

I had this on my RRS earlier this year, it would've covered about 50,000 miles at the time I'd guess. Same as you I had a new rear bearing & driveshaft but that didn't fix it completely. LR then diagnosed a knackered bearing in the TC and replaced the bearing under warranty. Also comes with a new flange & seal and wasn't much of a job to do (main dealer did it).

They had a slight issue on re-assembly where they couldn't then select low range, so it had to come back out again. They found some damage to the wiring loom above the gearbox / transfer case, possibly done during the removal / refit, so repaired it and it's been fine since. Worth making sure everything works as it should once the car's back together.

Had the Transfer case and rear diff (with electronic diff lock) replaced at 95,000km's.
Used stethoscopes to diagnose.

Was that under warranty still? Would hate to think of the costs.....

We're out of warranty and the car has 128,000km, with the T/C fluid being changed at 126,000....

Thanks for the input so far guys... also found some info sheets on another LR forum suggesting to disconnect the prop shafts and listen to see if the noise is still there, and if the output shafts on the T/C are spinning true. (it suggests bearings if they aren't, but if they are fine its possibly a whole new T/C)

Car is getting checked by the other specialist this thursday

It looks like a bearing in the T/C or the front diff, won't know till next Wednesday when the propshafts are removed to see.

rebuilt T/C is $2,800 + fitting
diff is $2000

The guy that rebuilds the t/c's says he's supplied a number to Ritters, Lance Dixon, ULR and a few other places.... So it doesn't seem like its overly uncommon.

Check out the price of a transfer case from the UK, I'm damn certain it wasn't that much for a a new one, never mind rebuilt.

We had this problem at 30000k it turned out to be a very bad wheel alignment and crook lower control arms that chafed our tyres, the dealership did repeated wheel alignments on it to the point that we had no adjustment left and it had to be pulled apart and redone from scratch, dealership also diagnosed tailshaft then diff then wheel bearings but it was none of these. A proper wheel alignment done right plus new tyres and new lower control arms should fix the noise entirely. One thing we also noted was that the whine increased and decreased with speed and was worse in cornering as you would expect with a faulty bearing and was also pulling slightly to the left but the wheel alignment and the lower control arms have fixed the problem. We have no issues with our vehicles steering and handling and ride and we are very happy with ours except for the towbar issue we currently have.

A crook bearing in the transfer or diff would not alter on cornering. It is only wheel bearings that do this.
