What is the width of the rear axle on a 2005 Toyota 4Runner?
The rear width most commonly cited for a 2005 Toyota 4Runner is the rear track width—the distance between the centers of the rear wheels. For this model, that figure is roughly 62 inches (about 1,575 millimeters). Exact measurements can vary slightly depending on wheel and tire choices, as well as any aftermarket spacers.
Understanding the measurement
In automotive terms, “width” usually refers to the track width rather than the axle housing width. The rear track width is what matters for tire clearance, wheel fitment, and overall stance. Some manufacturers publish axle housing dimensions, but for consumer purposes the track width is the standard reference and is the figure most enthusiasts and technicians use when discussing width data.
Official data and typical figures
Toyota does not always publish a separate, consumer-facing “rear axle width” figure. In practice, the rear track width is the commonly cited measurement for the 2005 4Runner, and that value sits around 62 inches, with modest deviations depending on wheel/tire configuration.
Variations by trim and wheel setup
Wheel size, offset, and any spacers can modestly alter the overall width as experienced at the body. Factory configurations with OEM wheels and tires align with the standard track width, while aftermarket wheels or spacers can push the track outward or inward by small amounts.
How to measure accurately
To verify the width on your vehicle, you can measure directly or consult official measurements. Here is how to measure accurately:
- Park on a level surface with the rear wheels straight.
- Measure from the centerline of one rear wheel to the centerline of the opposite rear wheel. This distance is the rear track width.
- Use a tape measure or a laser distance tool, ensuring the measurement is taken at the wheel centers and not at the outer edges of the tires.
- Record the measurement in inches and convert to millimeters if needed (1 inch = 25.4 mm).
- Consider any spacers or aftermarket wheels; re-measure with those components installed if your goal is to know the exact configuration for fitment.
Measuring the rear track width helps with tire clearance, wheel fitment, and understanding vehicle dynamics. Small changes in wheel offset or the use of spacers can lead to measurable differences.
Where to find official data
For official documentation and exact figures, try these sources:
- Toyota factory service information through the Toyota TechInfo System (TIS) or dealer technical resources.
- The 2005 4Runner’s service manual or owner’s manual, which may reference track width in specifications.
- Reputable repair manuals (e.g., Haynes, Chilton) that cover the 2003–2009 4Runner generation.
- OEM parts catalogs and Toyota technical publications that list axle and track width specifications.
Because official published track widths can vary by market, trim level, and wheel configuration, checking the exact spec for your VIN and wheel setup yields the most precise result.
Summary
In short, the rear track width of a 2005 Toyota 4Runner is about 62 inches (1,575 mm), with slight variations based on wheel and tire choices. For the most precise figure, consult the vehicle’s official service data or measure the wheel centers on your specific build.
