Buddy of mine contacted me today, asking if I knew what was going on
with his Jeep. I'm at a loss, hoping someone here might have a
suggestion. Here's his description:
"i was driving home from work yesterday, when all of a sudden WHUMP -
it was like I applied the brakes hard and quicky...then let off them
to keep moving
but since then, whenever I'm moving - I hear this click click clikc
click sound that increases as I go faster. Also, I feel the vibration
of it when i hold the shifter in my hand..."
The sound only occurs when moving, and increases with speed. Putting
the Jeep in neutral does NOT eliminate the sound. Sounded like simply
a rock in the tire tread to me, but he apparently verified that's not
the case. Suggestions?

You sure could be describing a blown u-joint.
You need to block the wheels and put it in neutral to unload the
driveshaft and go under and inspect and twist and turn the u-joints.
He has 2 on the back driveshaft, 3 on the front and 1 out near each
front wheel.
I suspect the rear from your description.

They don't mess around, Blow a bearing and the wheel falls off or flops
around big time.

Stop driving it till you check the drivetrain.
My first guess is a U-joint has gone bye-bye.
If a rock is causing vibrations it's going to be
a rilly BIG rock. :)

Hi Dave,
You are describing the transmission's output bearing, probably what
he felt was it's ball separator cage coming apart.

Thanks Bill... but would the sound/problem exist even in neutral if
that was the case?

The vehicle moving spins up the transmission from the driveshaft.

Maybe have your friend coast it down a hill with the transfer in
neutral to see if the sound is the same as just the transmission in
neutral.
