2005 Toyota 4Runner: The One That Still Runs When Everything Else Quit
The 2005 4Runner came with two engine choices, and honestly picking the wrong one will cost you more than you'd expect. The standard V6 is a 4.0-liter 1GR-FE making 270 horsepower and 278 pound-feet of torque. The five-speed automatic that pairs with it isn't sporty but it lasts. The SR5 trim adds things like fog lights and a rear spare carrier, while the Limited throws in leather and a power tailgate that breaks after three years. Here are the numbers you need. Curb weight runs from about 4,100 pounds for the two-door to 4,400 for the five-door. Fuel economy is 15 city, 19 highway, 17 combined with the V6. Ground clearance sits at 8.6 inches. Approach angle is 31 degrees, departure angle 26 degrees. Towing capacity maxes out at 5,000 pounds when properly equipped. The four-wheel-drive system is part-time with a shift-on-the-fly transfer case and a low range ratio of about 2.565 to 1. Wheelbase is 105.1 inches. Track width front and rear is roughly 60 inches. The suspension uses double wishbone up front and a four-link solid axle in back with coil springs all around. Brakes are four-wheel disc, 12.9-inch rotors up front, 13.0-inch in back. Standard tires are P245/75R16 all-terrain.
What Actually Makes This Truck Worth Buying
Body-on-frame construction. That's the short version. Unlike crossover SUVs that use unibody platforms, the 4Runner sits on a separate ladder frame. This means it handles abuse differently. When you're driving over washboard roads or parking on uneven surfaces, the body doesn't flex with the chassis. It just moves as a unit on the rubber isolators. That sounds like a small thing until you've driven both. The 1GR-FE engine is fundamentally different from the previous 5VZ-FE that ran in earlier models. It has VVT-i on both intake and exhaust cams, aluminum block and heads, and a timing chain instead of a belt. Chain tensioners can go bad around 100,000 miles and you'll hear a rattle on cold starts. I replaced both OEM Toyota tensioners and the chain itself at 118,000 miles. Cost was about $680 in parts. The old chain had stretched past specification and was skipping teeth under load. That engine can reach 250,000 miles if you change the oil every 5,000 miles and never let the coolant sit unused for more than a year. Four-wheel drive operation is straightforward but people mess it up constantly. The transfer case is an electro-hydraulic unit called the ECT-FT. You select 2H for normal driving, 4H for slippery conditions, and 4L for rock crawling or deep mud. You can shift between 2H and 4H while driving up to 55 mph. But 4L requires coming to a complete stop. I watched someone try to engage 4L at 30 mph on a gravel road. The indicator stayed on FLASH and the transfer case refused to lock. He drove it home, listened to the grinding, and needed a full rebuild at $2,400.
The Problems Nobody Talks About
Rock Auto parts catalogs list a known issue with the front lower control arm bushings. The rubber degrades faster than it should, especially if you live anywhere that uses road salt. At 80,000 miles your steering will feel vague. The wheel will wander on the highway. Replacing just the bushings is possible but it's a press-fit operation that requires a shop. I bought complete control arms from Toyota for $189 each and did it myself in about two hours per side. Torque spec on the lower bolt is 87 foot-pounds plus a quarter turn. The air conditioning compressor clutch gap closes over time. You'll notice the AC blows cold for ten minutes then starts blowing warm. The clutch engages and disengages rapidly. Cleaning the gap with feeler gauges sometimes helps temporarily. Most people end up replacing the whole compressor assembly. The aftermarket units from Denso or ACDelco are cheaper but the OEM Toyota unit from the dealer is what you want if this vehicle matters to you long-term. Interior plastics get brittle. The dashboard cracks around the gauge cluster and the center console divider splits. I've seen this on vehicles with as few as 60,000 miles in Arizona sun. Touch-up paint doesn't fix it. People use Flex Seal or vinyl dye as a cosmetic cover-up but the structural integrity is already compromised. It doesn't affect driving. It just makes the cabin look terrible.

Real-World Ownership Costs
Oil changes every 5,000 miles with full synthetic. That's $45 at an independent shop or $30 doing it yourself with a $15 filter. Transmission fluid should be changed every 60,000 miles if you plan to keep this past 150,000. The factory service interval says lifetime, which is manufacturer-speak for we don't expect you to still own it. Drain and fill costs about $90. Deep flush runs $180 but the pan drop method gets 70 percent of the old fluid out and that's sufficient. Tires wear through in about 35,000 miles if you drive mostly on pavement. Going to all-terrain mud and snow tires improves traction but drops fuel economy to 14 city. Brake pads typically last 40,000 miles. Rotors need replacement every other pad change. Expect to spend $400 per axle at a shop or $200 in parts yourself. Insurance averages $900 to $1,200 annually depending on your location and driving record. Registration varies wildly by state. In Texas it's roughly $180 per year for a vehicle this age. In California with the smog check requirement it's closer to $320.
When This Vehicle Fails Completely
The 2005 4Runner is not a performance vehicle. If you want quick lane changes or confident mountain passing speeds, buy a Subaru Forester or a Jeep Grand Cherokee. This thing corners like a delivery van. Body roll is significant. Braking distance from 60 mph is about 140 feet, which is adequate but not impressive. Quarter mile time is 18.5 seconds at 75 mph. That's slow even for a truck-based SUV from 2005. Off-road capability is genuine but limited by the factory tires and suspension tuning. The 4L mode works well for crawl control at walking speed. Beyond that you're risking drivetrain damage. I took one up a trail in the San Gabriel Mountains with stock suspension and 40,000 miles on the odometer. We got stuck on a rock garden section where the front crossmember scraped. No damage to the frame, no leaks, but the skid plate needs to be upgraded if you plan serious trail use. The budget solution is a $200 skid plate from ARB or Superlift. Spare parts availability is good for routine maintenance but body panels are getting scarce. If you get into an accident the rear quarter panel for the five-door costs $380 and ships from Japan in six weeks. The two-door parts are even harder to find. Interior trim pieces follow the same pattern. This matters if you're considering this as a daily driver in an area where repairs take time.
Bottom Line on the 2005 4Runner
This is a vehicle that trades comfort for capability and reliability for modern features. The V6 engine is adequate, not exciting. The interior feels dated compared to anything built after 2010. But the frame, the transfer case, the basic mechanical layout, these don't change much from year to year and that's why they work. A 2005 4Runner with 120,000 miles and clean maintenance records will outlast a 2018 crossover with half the mileage simply because the engineering philosophy behind it prioritizes longevity over refinement. Buy one if you want something that starts in minus twenty degree weather, carries three kids and a dog, and still goes somewhere most SUVs can't. Don't buy one if you care about fuel economy, quiet cabins, or having backup cameras. The 2005 model doesn't have any of those things and that's not a defect, it's just the era it came from.
