2004-2010 Sienna CV Axle Pair – Front Driver and Passenger Side

This 2004-2010 Sienna CV axle pair is a set of two front CV axle shaft assemblies, left and right, listed for the 2004–2010 Toyota Sienna minivan. The left axle is listed under reference number 4342008020 and the right under 43410-08030. The right axle is much longer than the left, and both use a 24-tooth input spline and a 30-tooth output spline. Easy Life Markets offers the pair for Sienna owners and workshops who want to replace both front axles together.

The Sienna drives its front wheels through two CV axles, and on this generation the right-hand axle is considerably longer than the left because of where the transaxle sits. Each axle uses constant-velocity joints at both ends so that power flows smoothly while the suspension moves and the wheels turn. Rubber boots filled with grease protect each joint. A minivan often carries a full load of passengers and luggage, which puts steady stress on the axles, and once a boot splits the joint wears quickly. The constant-velocity joint article explains the design in more detail.

Checking Fitment

The supplier lists this pair for:

Toyota Sienna, 2004–2010, front left and front right

The Sienna was offered with front-wheel drive and all-wheel drive in these years, and axles can differ between versions. Please confirm the details before ordering:

Look up the part numbers in a Toyota parts catalogue using your VIN and compare them with 4342008020 (left) and 43410-08030 (right).
Count the splines on your old axles: 24 at the transaxle end and 30 at the hub end.
Measure each old axle compressed and compare it with 28–30 in (left) and 40.4–42.4 in (right).

If you would like us to check with you, contact us with your VIN before you buy.

Signs Your CV Axles Need Replacing

Clicking or popping when turning in car parks or at junctions
Grease sprayed on the inside of the wheel, brake parts or undercarriage
A torn or cracked CV boot
Vibration under acceleration, especially at motorway speeds
Clunking when shifting into drive or reverse

Worn wheel bearings, engine mounts and suspension bushings can cause similar noises, so it is worth checking the front end before replacing parts.

Installation Tips

Loosen the axle nuts before lifting the van, then support it securely on stands.
Following your service manual, separate the suspension parts needed to release each axle from the hub.
Remove the long right axle carefully and support its full length so it does not hang from one joint.
Inspect the transaxle seals and replace any that are worn or leaking.
Fit each new axle to its correct side, make sure it is fully seated, and tighten all fasteners to the specified torque.
Check the transaxle fluid level and road test.

Because CV axles are part of the steering and drive system, professional installation is recommended if you are not experienced with this kind of repair.

Why Replace Both Front Axles on a Sienna

Minivans often reach high mileage while carrying heavy loads, so both front axles tend to wear at the same pace. Replacing both at once saves on labour, gives even handling on both sides and reduces the chance of a second breakdown soon after. The 2004-2010 Sienna CV axle pair supplies the correct left and right axles together, including the long right-side shaft.

Care Tips for Your CV Axles

Check both boots for splits whenever the van is raised for tyres or brakes. Keep the underside clean in wet or salty conditions and avoid heavy throttle with the steering at full lock. A quick look at the boots a couple of times a year can add a lot of life to the joints.

Tools and Parts to Have Ready

Have a large socket and breaker bar for the axle nuts, a torque wrench, a pry bar for the inner joints and sturdy stands ready before you begin. New axle nuts, cotter pins and transaxle seals are useful spares. Put a drain pan under the transaxle to catch any fluid that runs out and keep the correct fluid on hand to top up afterwards. Lay each old axle next to its new replacement to compare lengths and splines before fitting.

Who These CV Axles Are For

This pair suits owners of a 2004–2010 Toyota Sienna, family van drivers, independent workshops and DIY mechanics who have confirmed the left and right reference numbers or matching lengths and spline counts.

Common Questions

Is this a genuine Toyota part? No. These are unbranded aftermarket CV axles listed under reference numbers 4342008020 and 43410-08030. They are not genuine parts of the vehicle maker.

Why is the right axle so much longer? The transaxle does not sit in the centre of the van, so the two front axles need different lengths to reach each wheel. The supplier lists 28–30 in for the left and 40.4–42.4 in for the right.
