A case study in tinkering
run amok... by TD (Troy) Graham

Part 1: Genesis.
After beating the stuffing out of
Mazuki for two years, a few things became apparent: The rotary motor
and tranny were keepers, handily kicking the teeth out of both the
original Zook motor AND the breathed-on 1.6 I'd previously had in there,
using any yardstick. The modified Zook axles and the GRS2 tcase
stayed glued together, the REP8000 winch survived, the new MT/Rs rocked in
the rocks, the RCI seats are an off-camber lover's gift from above, etc,
etc.
But some serious limitations of
the basic vehicle were beginning to show through.
Abusing the thing in the
rocks every chance I got, and with the amount of trail rash she now was
wearing, avoiding a potential rollover situation was becoming less of a
concern with each new "badge". True, she was stout, only
logging 1 shattered U-joint and 2 tcase rubbers through the thrashing, but
in the meantime I was mentally logging a whole laundry list of items to
re-engineer over the loooooong Indiana winter of 2000/2001:
Axle wrap: The
torque of the motor, through the GRS2, was wrecking my springs and
U-joints... and I'm always conscious not to stick my foot into it when I
feel things load up. In Attica (where I do most of my playing) I
couldn't run the sand hills any more, AirZuk style... which was one of the
reasons for the rotary in the first place.
Steering:
The Breeze crossover system worked acres better than an old drop drag
link, but without a panhard rod, the missing links made steering nigh
impossible at times. Even with 2-3/4" backspaced wheels, my
front tires were rubbing the springs at full lock. And muscling the
fully-locked front all day was a pain (I'm lazy if nothing else).
Leaf springs:
Their incessant squeaking, and short life span, coupled with wonky on-road
handling was spooky... Mazuki also had developed what Naval types term a
"list" to the right rear corner.
Leaf spring
hangers: All four were seriously knackered, one was close to
terminal; they were getting dragged over everything. Mid-summer I
had to spend an hour or two beating them back into shape and welding
1/8" plate over the open sides.
Missing Link
shackles: Although they afford some nice flex, they stick out of
the front and rear of the vehicle 4" more than stock, making a
serious dent in your approach/departure angles. Putting poly bushes
in them to make them on-road tolerable cost me flex, so I compromised with
rubber in the spring eyes... but it's just that: a compromise.
Front driveshaft:
Even with "clearancing" the yokes, the tcase-end U-joint would
bottom at full droop, causing the tcase to chatter and shake like you'd
just blew an output bearing.
Winch mount:
Sticking out 10" in front of the vehicle wasn't helping my approach
angle any... an 81" wheelbase vehicle that was now close to
12'-0" in overall length.
Rear bodywork:
In the way... i.e.: many "lovey spots" to show off. And
the tailgate was kissed by a tree over a year ago.
Front fenders:
Even with liberal clearancing, I was still rubbing my 33" tires.
In addition, the front corners were starting to look a little (OK, a lot)
worse for the wear.
Fender flares:
Part of my post-ride maintenance ritual: putting all the fender flares
back on. For no other reason than to hide the UGLY extrusions that
I'm too lazy to remove.
Rockers:
Score: 1/8" diamond plate rockers, ZERO, rocks ONE; can't get the
driver's door shut now.
Conferr tcase
skidplate: &#!@%! J-bolts; a stout plate, just a poster-child
PITA to remove/install. Not to mention the 2" of ground/breakover
clearance I'm losing with it.
Motor mounts:
If I did roll'er over on the roof, I was afraid they would wouldn't hold
the motor.
Stock Mazda 4V
carb: Although better off-camber than ANY other carb I've
seen... it still has a limit.
Silver sucks:
I seem to be cursed with only being able to purchase silver vehicles, and
as a matter of fact, it's a running joke among my friends. The
reality is, silver don't get you in the mags. Even though I run the
ZookiMelt, and spent some time with the photog, did I get a mug shot in
the mag? Noooooooooo...
Plus many other little
foibles. My original thought was to address most of these bugs,
along with a serious spit-and-polish session to spruce the old girl up.
But there were some things, like the rear bodywork, I just couldn't
"fix".
TD's Quips, Chapter 3, Verse 12:
"Don't treat the symptom, fix the (insert appropriate expletive)
problem."
For instance, even though I might
add a panhard rod to the front, and a traction bar to both ends, I still
have to deal with the inherent leaf spring approach/departure angle,
squeaky, shifty, saggy hassles. Therefore, the problem ain't fixed,
just shifted it to another area (accountants seem to be particularly adept
at this). Besides, I'd be halfway to a full-linkage setup at this
point, which would actually fix a myriad of problems, in theory anyway.
I wasn't going to solve my body
clearance problems (I mean Mazuki's!) without either a spring lift, a body
lift, or both. Great, now my center of gravity (CG) goes out the
window. And I'd still be rashing the the sheetmetal. So why
not remove the parts that are in the way, ala Todd Myers'
"Sniper"?
Need some form of power steering,
but I have yet to witness a system on any big tired/locked vehicle that
don't squeal, leak, throw belts, or all three at once. Last year,
the guys competing in the rock crawling contests were starting to tinker
with full-hydraulic systems, which were working out quite well.
Then, four-wheel steering is just another short step...
It was this sort of thinking that
sort of got seriously out of hand about last November, and started me on
the path designing a complete, ground-up rebuild/conversion around the
parts that work, binning the ones that don't.
Like I said... a loooong winter:
