Hummer H3 CV Axle Pair – Front Left and Right, 2006-2010

This Hummer H3 CV axle pair is a set of two front CV axle shaft assemblies, driver side and passenger side, listed for the 2006–2010 Hummer H3. The supplier gives one reference number for the axles, 15886012, with a compressed length of 25–27.3 inches (634–694 mm), a 28-tooth external input spline and a 33-tooth external output spline. Easy Life Markets sells the two axles together, so H3 owners and 4x4 workshops can renew both sides of the front end in a single job.

The H3 sends power to its front wheels through a front differential and a CV axle on each side. Every axle has an inner joint that plunges in and out with suspension travel and an outer joint that lets the wheel steer. Both run in grease behind flexible boots. The H3 is a heavy truck that often gets used off the tarmac, and bigger tyres or a levelling kit put the joints at steeper angles than standard. That is hard on boots. Once one splits, grit gets into the joint and it does not take long before you hear it. For background, see how a constant-velocity joint works.

What Is Included

2 x front CV axle shaft assemblies (left and right)

The product photo shows two matching axles, each fully assembled with both joints and boots fitted. Hub seals, differential seals and other hardware are not listed as included.

Checking Fitment

The supplier lists this pair for:

Hummer H3, 2006–2010, front left and front right

The listing does not break fitment down by engine or trim, and it does not mention the H3T pickup. Rather than rely on the year alone, please check these points:

Look up the front axle shaft part number for your truck in a GM parts catalogue with your VIN and compare it with 15886012.
Count the splines on an old axle: 28 teeth at the differential end and 33 at the hub end.
Measure an old axle compressed and compare it with 25–27.3 in (634–694 mm).
Think about modifications. A lifted or heavily modified H3 may need axles built for the changed geometry.

If you would like a second opinion, send us your VIN and we will help you check before you order.

Signs the Front CV Axles Are Worn

Clicking or popping from the front when turning, especially on tight turns
Grease thrown onto the inside of the wheel, the control arm or the skid plate
A boot that is torn, cracked or missing its clamp
Vibration under acceleration that fades when you ease off
A clunk as drive is taken up from a standstill

Wheel bearings, ball joints and front differential bushings can cause similar noises on these trucks, so look over the whole front end before ordering.

Installation Notes

Loosen the axle nut with the wheel on the ground, then raise the truck and support it on stands rated for its weight.
Following the service manual, free the steering knuckle enough to slide the outer joint out of the hub.
Release the inner joint from the front differential carefully so the seal is not damaged.
Fit the new axle, check the inner end is fully seated, and tighten all fasteners to the specified torque.
Check the front differential oil level and road test, listening for noise on full lock in both directions.

The H3 is heavy and this is steering and suspension work. Unless you have the tools and experience, have a qualified mechanic fit the axles.

Why Change Both Axles Together

The left and right axles have done the same miles over the same ground. When one boot has let go, the rubber on the other side is the same age. Most of the labour is in getting the knuckle off, and doing both sides back to back saves time. With the Hummer H3 CV axle pair you get both shafts in one order.

Looking After CV Axles on an Off-Road Truck

Check the boots after every trail day. Sticks, rocks and packed mud are what usually damage them, and a small nick turns into a split quickly. Wash mud off the underside before it dries, and go easy on the throttle when the steering is at full lock on a climb, because that is when the outer joints take the most load.

Tools and Parts to Have Ready

You will need a large socket and breaker bar for the axle nut, a torque wrench, a ball joint separator, a pry bar or slide hammer for the inner joint, and heavy-duty stands. New seals and the correct front differential oil are sensible things to have on the bench. Before fitting, lay the new axles next to the old ones and compare length and spline counts at both ends.

Who This Axle Pair Is For

This set suits Hummer H3 owners, 4x4 specialists and general workshops who have confirmed the 15886012 reference number, or matched the length and splines, for the truck being repaired.

Common Questions

Is this a genuine GM or Hummer part? No. These are unbranded aftermarket CV axles listed under reference number 15886012. They are not genuine parts of the vehicle maker.

Are both axles the same? The supplier gives one reference number, one length and one set of spline counts for the pair, and the photo shows two matching axles. Compare them with your old ones before fitting.

Do they fit the H3T? The supplier lists the Hummer H3 only. Check the part number for an H3T before ordering.
