not think how a tech who gets in the car and
puts it either on a dyno or puts a sensor in
the tailpipe to test the emissions could have
created this problem. Do the techs check the
timing manually? Some places, they inspect
for emissions equipment. But even then, they
are not working on the rig. So I could com-
fortably say that most emission stations would
not be working on your rig and could not
create your issue.

pull the crank and see if you have more than

with a dial indicator. If you have more than

the Rubithon (my favorite event). I spent time
looking my Cruiser over. I finally found that
a rock had worked its way down from the
shock mount and got in between the backing
plate. In turn, it put pressure on the outside of
the rear rotor. While it did not take that much
time, I had not wheeled the Cruiser for many
weeks when this sound showed up. So the
only time the rock could have hung up in that
area was on the trip many weeks before.

shop rebuild the transfer case and transmis-

Several parts in the transmission had to be
replaced due to wear and the rebuild kit
had new bearings and gaskets included
and installed. To date during the restora-
