These
pictures are from Dec 2001. Pat's 4 Runner was dubbed the "HMS
Murphy" due to it's sheer size and weight. He estimated close to
5,000 lbs. Most of this weight was from the complete EXO cage Pat had
fabricated, along with the entire stock body, trail spares, tools and a full-size
spare. All that weight was not friendly to the drive train.
Broken axles and birfields were pretty common for Pat so one day he posted some
pictures on the internet of the latest project he started.....


Would
you believe this is the same truck pictured above? In a few short days Pat
trimmed his 4 runner down to the bare essentials, a frame and drive train.


The
front end was built around a set of Lincoln Navigator headlights. Another nice touch was the frenched in rear spring hangers. By recessing
them into the frame, Pat eliminated one of the common hang-up points when
sliding the frame over rocks.




The
transformation shed at least a 1,000 lbs and the rig performs better at
everything from climbing to crawling. Also, trail breakages are now a rare
occurrence with the 5.29 ring and pinions being the weak link thanks to the
upgraded chromoly axles and superbirfs. Eventually he will switch
over to the stronger 4.10 ring and pinions.




Pat's
new lighter buggy was working good but by August of 2004 he was ready to go to
the next level and link up the rear. The leaf springs just weren't cutting
it, the biggest issue being the inability to climb some of the steeper obstacles
without a lot of wheel hop. He cut off the rear half of his buggy and fabricated
a double triangulated 4-link using Johnny-Joints on each end of the 40+ inch
long links. 18" Fox Air Shocks were used to support the rig and provide
dampening.




In August 2006 Pat's buggy went under
the knife again. The original plan was to build a new chassis but with the
price of material being really high at the time and no bites on his old rig he
decided to just take the pile of parts he has been collecting and install it in
his old chassis.

he new power plant is a 4.3l mated to
a TH350 and Dana 300 transfer case. To handle the extra power the Toyota axles
will be replaced with a D60 up front and a 14 bolt out back.




The finished project.
