Fail to proceed - LT230 Transfer Case

[Ranga]

Leaving home this morning, heard a bit of a rattle/clunk as I got to about 30kph. Had a poke around, couldn't really see anything obvious. Drove a couple of kms and a very noticeable whine got louder. After getting home, I've gone to drive out of the driveway and heard a loud clunk. From here on, the car was only able to slowly move, shuddering every second or so until I was able to get it off the road.

A mate believes it might be a rear gearbox shaft. Anyone able to comment from the vague info above?

Hey stranger,
Is it doing it both high and low range?
Could it possibly be an axle or diff?
It may be time break out the jack and stands to investigate further.

The original little clunk/rattle noise did seem to come from at least the middle of the truck - didn't sound like the detroit in the rear. Parked on the side of the road at the moment, so unfortunately bit of a ***** of a place to put it on stands. Might try to get it back in the driveway.

I managed to get it back into the driveway. I needed to reverse up 100m or so, and in doing so tested it in low range, which made no difference.

One thing I did notice, was when the vehicle was rolling the shuddering was still there with the clutch fully engaged. Not sure if this gives any further indication.

Might be time to put that auto box in that I've always thought about!

Try rolling with the transfer in neutral.
That should stop the gear box from turning.


What systems do you get from a flogged out axle flange?

[redrovertdi]

pull the inspection/pto cover off the back of the transfer case and pull out the gear, you then see if you have stripped the output shaft.
Autos arent perfect but alot better imo

Bad Luck ranger , Dropping the sump plugs for gear box and TC, diffs will probably tell the story. Hope it's not to expensive.
cheers simmo

Check the handbrake too. If something comes adrift in there & the shoes start grabbing, they can cause all sorts of strange noises.

Think I found the cause (see attachments).

Looks like a transfer case replacement is in order. Probably an Ashcroft I reckon. At least I get the new sleeve to stop the leaks . Also, luckily the gearbox shaft looks fine.

Ouch! That looks a bit of a mess At least its not the whole box.
