I read the thread from 10/19/10 wanted to ask some more questions.
I changed the universal joints on my drive shaft will check grease.
What in the transfer case would cause this?

When I brake normally or harder there is no clunk?
When I brake slowly I get the clunk?

Any help or advise would be much appreciated it annoys the hell out of me while hoping nothing breaks.

Check your trans mount bolts.

If it is only 1 clunk, it is your transmission having a hard shift down from 2nd to 1st gear. This is fairly normal for our trucks and nothing to worry about.

If it is a clunkity clunk clunk, then try and work out if it matches wheel RPM or tailshaft RPM. That will tell you where to start looking.

I think I know what clunk he speaks of. When the vehicle comes to a complete stop, it will thunk, almost seeming to be in time with complete stop. It was enough that for awhile I thought it was the caliper moving or something like that.

Do you have and use a remote starter?

I have the clunk too. I notice mine when I let the brake off from a complete stop. I'm suspecting the transmission mounts only because someone else told me this was what the clunk has a high probability to be. Wasn't there some engine mounts that were also a common problem for VX?

Mine was doing exactly the same thing many years ago. It was just the u-joints needing grease. (I've checked my transmission mounts several times, and they have never been loose.) I think there are 3 zerk fittings. A quick search should find everything you need to know. It's been discussed several times.

X2...same here and since I grease those and my sway bar at each oil change it has never come back...:bwgy::smilewink:bgwo::bgwb:

First time to do it took quite a bit of grease too.
