Hey Tommy (and anyone else listening),

I’m getting hung up on this whistle sound now,
I hear it around and above 2,500 rpm and mostly in 3rd and 4th but sometimes 2nd.

Goes away the instant I press the clutch.

Adjustments to the slave rod/fork downstairs yield no change.

Searching brings up similar but not same issues, lots of carb and vacuum leak threads as well as some that led to spun bearings 😳.

I’m pretty sure it’s downstairs and not under the hood. It’s just really hard to diagnose.

Leaving in two days for a +/- 2,000 mile round trip and I’m a wee concerned.

Throw out bearing? Clutch adjustment a wee bit too tight?

Do you have a video/audio clip?
 
Tried to get it on audio, too loud in the truck to hear anything meaningful but I’m starting to think it’s a bearing of some sort.

I’ve adjusted the clutch, greased the driveshafts and changed the fluid in the differential (all things similar threads pointed to) to no avail.

I’m going to have to punt and take the 62 to big bend. Just can’t risk throwing a bearing in the desert while solo.

As I was making this decision, Norman started running pretty poorly out of nowhere.
 
Tuff break. Better safe than sorry.

Nobody wants to read the “What ever happened to @RevISK” thread.

I have an old tried and true method for finding things like this.


Drive it til it you let the smoke out.

Just have a bag ready to catch it! It’s hell getting it all back in and they don’t ever run the same without ALL the smoke!
 
In my humble opinion if you are driving a 50 year old machine - have good walking boots and a day pack with you at all times. Meds, food, water, gun, gloves, hat, extra socks, knife, fire starter, sun glasses.... Some tools and parts never hurts either. HAM radio can be very useful where cell phones don't work

Whilst it's true that these are old rigs, I've been driving and fixing Cruisers for nearly 40 years now. I've broken down in the Tanamai Desert in Australia, on the Strezleki track in South Australia and on Opher Pass in Colorado. In every place I've broken down I've fixed it with tools and spares I've got with me.

I can't say that about any of my new cars: when my wife's '23 tahoe diesel"s DEF injection filter had a short, the computer made us drive 5 mph until we got to a Chevy dealer and were able to have them reflash it.

I still prefer driving my old cars to my new cars: risks and all. Just do it wisely like you are.

The chances of any new car today being on the road in 50 years are somewhere between slim and nill in my opinion. But the chance of these being on the road in another 50 years is pretty good unless we keep trying to outlaw ICE vehicles.

I’m pretty confident this 40 would make the trip, it’s just the last little bit of uncertainty. I’ve driven this truck for thousands of miles but this is the first time I’ve heard that sound and it doesn’t sound great.

I’m fortunate to have another LC to fall back on for the trip. Had to make the call and signs pointed this way.
 
Just fer cuz

Mystery noise?
Alright…

The weird jingle/whistle/rattle noise is making me insane. To recap:

- rebuilt t-case w/new throw out bearing, pilot bearing, clutch etc… with kit from Georg @orangefj45
- Happens only over 2,500 rpm while under load
- immediately stops when clutch is depressed
- clutch adjustment done from top to bottom per the FSM
- clutch bled
- throw out bearing adjusted about 4mm off the fingers
- new spring

It really seems/sounds/feels like the TOB lightly riding on the fingers it is just so hard to diagnose.

It does seem like the TOB and fork might not be consistently returning/disengaging and maybe that’s the issue?

How do I get the fork/TOB to return consistently?
