Hi everyone; I've recently put my '67 2A into service as my daily driver (it's been an occasional summer rig for 8-10 years) and I'm playing whack-a-mole with problems as they reveal themselves. On the ride to work this morning, a big one popped up.

Background:
I've been hearing a faint new scraping noise recently from right under the middle front seat - somewhere around the drive shaft / transfer case / parking brake which increases and decreases with the RPM of the wheels. Last time I heard something similar, it was the bell housing for the parking brake scraping against several broken brake parts inside (springs, etc), which I took out. When I reattached the housing, the noise went away. I haven't replaced the springs, adjustor, etc so I have no parking brake currently - not related to this.

Also a couple of times recently I heard weird scraping/grinding noises which were the 4wd becoming partially engaged and were solved by stopping and shifting into and out of 4wd.

Problem:
Then, today I was cruising along (still hearing that faint little scraping noise) when all hell broke loose from the same area - grinding, bolts-in-a-can rattling, etc. I pulled off the road, shifted into and out of 4wd and discovered that the yellow lever would not stay engaged (down) - I'm not sure if this is related. This didn't really help, but I was able to limp it home.

I can still shift fine - feels as smooth as ever, car tracks, steers, accelerates, brakes fine. I pulled the center seat out and eyeballed it quickly and didn't see anything obviously wrong (to an amateur eye), no fluid pouring out, etc.

I'm about to go dig into it and I'm hoping to get some advice as to how to go about eliminating possibilities and narrowing in on the culprit (or culprits). A warning: I'm working in a dark, poorly equipped garage - even little things take me a long time.

Thanks in advance!

Welcome Aboard :)

Nice bus :)

Sounds like your transfer box is rather unwell :( - First step IMO, drain the oil and see what condition it is in, and what comes out with it :confused: ( might be scary - might not )

Good luck - SIIA TB's are simple enough ....
 
Thanks, gents. I took the parking brake apart and found that part of the spring assembly / tensioner (which I hadn't removed) had self-destructed. So it was exactly what it sounded like - a bunch of metal pieces bouncing around in a metal housing.

This does not fix my transfer case problem. I'll learn the system here and take that over to the proper forum!

Cheers!
