Transfer Case High is gone

[ShootingCar]

I was driving my '69 Series IIa 88 home tonight, when as I was going up a hill, I heard a loud bang and suddenly no drive train. I coasted back down and started trying to shift the transfer case shifter. It would drive in low range but when shifting to high range it appeared to just be in neutral. I ended up having to drive it home 5 miles or so in low range. It was singing but I got home going up to 20 mph with fifth gear. What have I done and how do you recommend I fix it? Remember I am all thumbs with this stuff and this is my first major breakdown.

Any help would be appreciated.

first thing id do is take off the bottom cover, and see whats up. maybe a good idea to strain the oil when you drain it to see whats in the oil.
i just recently replaced my transfer case with a rebuilt unit from rovers down south. its a big job to do, but i managed it in a weekend by myself pretty easily.. it was outside in the winter too, which made working on it a pain, but it was still a pretty straight forward task. thats your worst case scenario anyway, so its not that bad.

Unlikely its the t-case. probably broken rear axle. Try it in 4wd high see if it goes.

I agree with Ike's take on this, at least check it out.

X2 on the broken axle.

It's a broken axle

Wow Ike, you know how to pick em. I tried it in 4wd high and it ran fine in the driveway. So it must be a broken axle. So when you are in low range is it always in 4wd then that it would run in low range?

Thanks for the direction everyone. Wow the power of the internet.

It is the big bang theory. Hear a big bang, loose the connection between the engine & wheels, it is the rear axle breaking.

Most rear axles are good for about 45K miles, less if you take a 109 off road.

Replace both axles and if the broken axle broke on the inside, remove the diff and clean well to get any chips out. If you just replace one, the other will break before too long. The cure of course is to replace with a 24 spline upgrade. Or just replace both with new 10 spline ones every 40K miles before they break.

And for an 88?

Just curious......lifespan of axles the same for 88's?.

Yep, I blew my rear 10 spline going around a turn at 10mph a few months ago

where do all of the axles come from

My truck actually has Range Rover axles on it from the coil conversion from ECR years ago.
I looked for replacement axles for my truck. RN only had one used right side and one new left side and said that per Land Rover in the UK, the right side was no longer available. Atlantic British had only one new right and left, which is where I got them both from.
So if all of us are breaking these axles all the time, then where are we going to get them from? Do you guys carry spares with you?

thanks for all your help.

After breaking seven 10 spline rear axles over the years I converted my 109 over to the much stronger Salisbury 24 spline rear axle assembly (stock set up for SIII 109s). To which I added the stronger ARB diff, stronger Great basin axles and drive flanges. This was 14 years ago. Haven't broken anything back there since.

After breaking one front axle & twisting a second My front is converted to the stronger 24 spline SeriesTrek front axles and stronger 24 spline Truetrac diff.

I gave up on 10 spline Rover axles and the weak Rover diffs.

WTF? I bought my first series truck 40 years ago next month. I've lost count of how many I've had, but pushing 3 dozen, and I have yet to break an axle shaft. I bought a spare R&L 25 years ago, but so far, haven't even taken them out of the cardboard tubes. What am I doing wrong?

Terry,
How do you expect the part suppliers to stay in business with you pussy footin' around with your axles for the last forty years. They have mouthes to feed too you know.

rear axles

1968 ambulance/camper, broke standard axle, replaced with Salisbury, broke one of those, got Great Basin axles, years and nothing broken. Detroit locker in rear now, still nothing busted.
