Thread: If my transfer case was a dating app it would be Grindr

That is the obvious reason, but before starting on that, I would check whether it is a diff - noise from these would be transferred along the prop shafts and sound as if it were coming from the transfer case. Jack up each end, one at a time and rotate by hand - if its making that much noise, it should be able to be felt. And, obviously, make sure the diffs have oil in them. (If you have free wheel hubs, this enables you to rule out the front.

It could also be a wheel bearing - and turning each wheel by hand while jacked up should immediately show if this is the case (and check for free play while doing this).

Remember that as soon as you jack up a back wheel the handbrake is not effective - chock the front.

Transfer cases rarely suddenly become noisy as you describe, but there is one fault that could have that effect - if the nut on the back of the rear output shaft has come loose, it will remove the preload on the bearings and allow the gears to come slightly out of mesh. This can be checked by unbolting the rear prop shaft and checking it.

Rereading your description, sounds more like a wheel bearing.

KISS UJ?

Thanks for the quick responses. My friend and I will have a crack at that tomorrow evening and report back. Fingers crossed it’s not too major!

Could be any or all of the above. I would start with having a good hard look at the universal joints and then go from there.

So I did a bit of poking around
and there are two things.

Firstly - the U.J.s seem good and solid and quiet and the diffs seem silent, and so does the transfer case.

The front left is making a sort of metal-on-metal squeal when turned, but almost sounds just like a bit of something caught between brake drum and shoe, and is doing it equally in both directions.

The other thing I can see is where the prop-shaft enters the rear diff, where it slides in and out to allow for suspension movement, there is a full 2mm of play around there. I’m assuming there’s a bearing in there? You can rattle it by hand side so it’s quite loose, even though it still slides smoothly in and out.

Do you think this is the problem?

If so, is it a job I could do without taking the diff out? What are the costs involved?

Also, is there a PDF workshop manual on here that anyone’s selling?

Thanks

The input to the rear (or front) differential does not slide in and out. This movement is on a slip joint on the propeller shaft. If there is any sideways play on the input to the rear diff, there is a problem. Disconnect the prop shaft and check the nut on the pinion shaft for tightness - If loose, tightening it may fix the problem, but there is a good chance the bearing has failed. This is a diff out issue, and the whole differential assembly will need to be checked at least. The pinion seal is certain to need replacing as well. The seal and outer pinion bearing could be replaced with the diff in place, but you have no idea what the rest of the differential is like, and the inner bearing is almost certainly in the same condition.

Do you think this is the problem?

Yes. But there may be more than one problem!

Look at "shop" in the top bar of the forum header, and look for "Rave CDs"

Are you implying that a certain bloke is rooting it?

Just that it’s rooted 🤣

I was going to take it to British and American 4WD as it’s practically across the road but apparently they’re in the process of moving shop (and not answering the phone). Any good Landie shops over West Side (of Melbourne - I’m in Kingsville)?
