I probably won't go too far with mods, just the essentials - but that's what they all say, right?

I bought my 2001 Toyota Prado 3.4L in early 2010. It came from the first owner, completely original and had never been used offroad. Since then it's been through 3 stages of mods, blown a front diff, several failed CV axles and created a collection of snapped sway bars.

- heavy duty sway bar, 22mm rear, Superpro

DRIVELINE:
- ARB Air Lockers, front & rear

- Custom mud flaps with tie up chains

ENGINE:
- Pacemaker extractors, custom 2.5" exhaust

    Battery Tray

    August 2010

    The 3.4L's come with a pretty small battery (230mm), so I decided to fit a larger one in the stock position. This meant fitting a larger battery tray. Piranha Offroad make a replacement tray for 305mm batteries, but it comes at a hefty price of $150-$200. Also, I didn't want to go that big, due to the weight. So here's what a friend and I put together for around $15...

    Left: Original plastic tray.
    Right: New stainless steel tray (260mm).

    Two nuts were welded on to keep the tray in place (sizes M10 and M12, with a little grinding). You could use tubing, bolts or anything round.

    Added a thin sheet of rubber to absorb shock and reduce slip. I used Neoprene instead of standard rubber, because it's chemical and heat resistant (200mm x 1.5mm from Clark Rubber).

    It sits firmly in place place without any need to drill holes or bolt down.

    PS: The original mounting bracket can be used (as long as the new tray is centered correctly).

    UHF

    January 2011

    I finally bought a UHF last week, and installed it last night. I ended up with the GME TX3340 for it's size and mic control - which allows a very discreet and tidy install.
    There's a spot just under the steering which was designed for a speaker, so I've mounted it there with some custom steel brackets:



    The mic has all the controls and comes with an extension - which still needs a proper install, once I've decided on the location.

    Blown diff & ARB Air Locker

    February 2011

    After braking my front diff on a PP drive I had an ARB locker installed in the front.
    Photos from the scene:




    The trip home was on a tray. NRMA roadside was very handy for this, not only for getting the vehicle home, also moving it between workshops.

    Front diff damage, vehicle rear side spider gear:

    Some damage on the lower gear, which belongs to the driver side wheel. This is clearly where the failure occured (right wheel spinning in the air, then hits ground, and stops = snap).

    Replacement diff with Air locker installed (hose on right):

    Compressor located on driver side of engine bay:

    Headers

    August 2011

    I finally decided to spend some coin on some Pacemaker extractors - to get rid of that flat spot at 2,700-3,000 RPM.
    First up, the key ingredient to all home mechanics: (did anyone spot this? kav??)

    The new and old (the old gear is much heavier):

    Some studs need to be removed in order to get the new headers in place:


    Driver side done:



    Umm, that's all.. I didn't take many photos because it was a hard job.
