Thread: D2 TRANSFER CASE VIBRATION DAMPER

Have been getting the rattle that seems to be common with D2's at 2300rpm for a little while now. While underneath it today prepping for easter weekend, lay underneath while was was running and managed to isolate it to what i have always looked at as being a mount on the rear output housing.

Revving it up found it to be the source of the rattle, pushing up on it stopped it.

Both the case mounts look a little flexible but after a quick look at Microcat shows it as being a vibration damper.

Anyone ever had any experiences with these failing for any reason as i know this rattle has been mentioned here numerous times before.

Screenshot from Microcat, its item 29.

I had what I thought was a leaking transfer case seal.

When I dismantled the handbrake assembly and removed the seal it turned out to be a leak past the top bolt that holds the vibration dampener on.

IE the thread goes into the transfer case through the weight and then a nut is secured to it.

So in effect I need not have replaced the transfer case seal.

The damper was rattling not long after I got the bus and I tightened it with a 15mm spanner and then a few months later the leak appeared.

When you look under it you see a few drips coming down

It looks like the handbrake drum. So I assumed the leaking seal.

I also had the rattly handbrake shoe.. It drove me insane for more than a year before I manged to diagnose it.

And then plucked up the courage to tackle the job myself.. The several quotes I got were not affordable.

Nobody could or would give me a firm cost to cease the noise.

In the end it was a cheap (under $50) but very satisfying job to do.

Cheers.
