Whatever it is, if it's annoying enought to hunt for, work from
"easiest to hardest".Take the top off the trans, drain it
and clean it out completely.I stress this.All gears look
great with gear oil covering them.Amazing how cleaning them
up can change that look.Have you a tooth or two missing from
your second and high slider or the high gear on your cluster?
This condition makes an excellent click. No?Move on. Remove
the handhole cover of the bellhousing. Find a "little person"
to stick their hand and arm down to the bottom of the bellhousing
to fish for flora and fauna.You may find bendix bolts or
other cool stuff.If you find rivets and bits of spring, your
spring-center clutch disc is disintegrating.Remove all such
objects - take them out the radius rod ball cap hole if you
have to - put I just pull them out the top.Replace the disc
if you found related parts of that type. Try again.STILL
CLICKING?Continue the hunt...
Look at the speedo driven gear (little aluminum guy) on the
torque tube.If it's "ok" - not broken, chewed or missing parts -
look at the driving gear mounted on the driveline, down in the
hole.Try to move it up and down the driveline with a screw
driver.If it wanders up and down 1/4" or more, you found your
problem, most likely.Someone has left the snap ring off that
holds all the parts in place, or they left out the thrust
washer that takes up that 1/4".Either way, now you'll have to
pull the diff (that's easy with a spring spreader) and pull
it back far enough to install the missing pieces.All OK
at the speedo gear?You'll have to pull something to hunt
further, so it may as well be the diff.Look first at
the U-joint.There's a fine place for a click.No grease?
Lots of wear?All fine?Pull the left-hand axle housing only
and pull the axle/ring gear/bearing assembly out.Look for
bad teeth or evidence of a real bad mesh with the pinion.You
have at least one hub off, at this point.Examine the axle
key and the fit of the hub to the axle shaft.Nice and tight?
In the right place so it isn't hitting the emergency brake
backing plate?Keyway snug?Key good?Still no sign of a
problem?Did you find any loose, missing or broken brake
parts in there?No?Check the other side.Still nothing?
I give up.You didn't use the wrong length flywheel bolts
did you?
