I thought I’d make a build thread to track my progress. I bought my LX 450 from a mud member last August. It had a few kinks to work out, but I absolutely love this thing! Since I bought it for off-roading, I intended to do a full Raptor line job, but when they backed it out of the delivery trailer, I realized I had a bit of a gem on my hands, and that plan went right out the window. I also intended to do a bigger lift and tires, but so far, it has proven to be more than adequate as it sits, so that plan will wait until at the tires are shot, at least.
Mods as purchased in August ’23:
Drivetrain
Fresh engine and TRD supercharger 20kmi ago
Custom 3” exhaust
Suspension
Ironman 2” lift
33” Nittos on aftermarket wheels
Exterior
Depo headlights and “Land Cruiser Grilles” grille
Light bars – two big ones, two ditch lights on mirror plates, two rearward
Changed all fluids (diffs, t-case, and PS fluid twice – they were nasty)
Greased knuckles & drive shaft
Recharged A/C
Replaced front NWTI bumper with ARB Bull Bar, and added a Warn winch, Slee offset hawse fairlead.
This project was a debacle. I tried to install two different winches in the NWTI before coming to the conclusion that the bumper was assembled incorrectly, and ultimately replaced the bumper with an ARB after determining that the NWTI’s welds couldn’t be trusted on the trail.
32” light bar was difficult to fit, so it ended up on top of the bull bar, above the hood line.
Added AVS window rain guards and Fahren LED hi-beam bulbs (these things are unbelievable – money extremely well spent!)
Upgraded the Ironman springs with heavier load-spec springs, also Ironmans. It’s a fatso.
Added 2007 Tundra tow hooks ($10 from the u-pull). Rear holes had to machined oblong to fit. Refinished with Aluma-hyde (toughest spray paint I’ve ever seen, but avoid the flat black – it sprays in chunks).
Realized the main battery kept going weak after just a few days of sitting, and confirmed there was a parasitic draw. I found a jumper where the Power Main Relay should have been, and found a thread on mud discussing this as a “mod” so you can roll the windows down with the key out. Put in a new relay and the the draw is back in spec.
Since the passenger side low-beam was missing the bulb shield, and these can’t be bought, I didn’t want to install LED low beams and blind people, so I installed HID bi-xenon retrofits from The Retrofit Source. I love these lights! I also replaced the hood struts after it fell on and destroyed my drop light.
Braking was causing steering to the right, so I replaced the front brake hoses (inc. longer 2013 Tundra hose for FR #2, Toyota p/n 90947-A2015) and flushed the brake fluid again. Also fixed the leaking Speedo Driven Gear O-ring.
After the nightmare that was replacing the bad alternator, I could not bring myself to go through it all again to R&R the newly-leaking power steering pump, so I installed Prestone synthetic power steering stop-leak, which is a seal conditioner. It worked perfectly! I'll come back to the real repair later.
Installed a Safari snorkel. What a pain! I got it for Christmas, and took two months to decide whether I could bring myself to take a hole saw to a factory original fender. Shop estimates for installation between $400 and $800 motivated me to do it myself.
From purchase, the exhaust sounded tinny and had multiple, loud resonance points throughout the powerband, so I planned to upgrade it sometime in the future. I heard this clunking in the rear on a trail ride, which was the axle smashing the poorly-routed pipe over the axle, and then I backed the tailpipe into a rock, thus moving its upgrade into the present. I had a local muffler shop make me a custom 3" exhaust (cat back) w/two Magnaflow mufflers, which sound 1,000 times better! I also moved the exit to just behind the RL tire, so there won't be any backing into stuff and bending it.
Replaced air filter and ran two bottles of Techron. MPG is now up to 11.8, from 9.5 after purchase.
Replaced front light bar with one that fits inside bumper, where it belongs. Also installed a front flip-up license plate holder.
I noticed a film of oil building up around the oil filler cap, so I replaced the rock-hard oil seal.
Added clear windshield tint. Dropped interior temp in the sun to 20 degrees F lower than my tan pick up, and adds permanent UV protection for my uncracked dash.

After my last trail ride, I heard the horrible, tell-tale noise of a failed brake pad. Read the incredible story of the best customer service in the business here.
Over the last week, then, I installed F&R EBC Greenstuff brake pads and new rotors. I found the RR caliper was frozen, so I replaced them both, and while the lines were open, I did the rear brake hoses, with the longer center hose from a 1996 T100 (I had already done the front a few months ago). I've only been out to bed them in, so it's too early to say how much I like them but they feel pretty good so far.
I also adjusted the parking brake, which pulled up too high since I bought it. It took me two tries to get it right, but it now holds firm with eight clicks. It'll need a new cable if it ever needs to be adjusted again - it's all the way at the end of the threads.
This week I also finalized a four-tire filling system. I can go from 16psi to 34psi in five minutes, not including the setup time (I need to time that yet). This all started because a friend offered me this top-grade air hose that he snagged before it went in the dumpster at a warehouse he was closing down. With the free hose and a bunch of free fittings, I'm only in it for about $125.
I spent the whole day on the trail today, and my new brakes are terrific! I'm going to get Greenstuffs for my pickup, too. I especially like the improved initial bite.
I timed the full tire refill process today. From the moment I put my hand on the hood release to the time I closed the hood: 13:35.
Put in a new relay and the the draw is back in spec.
