Chevrolet K5 Blazer Double Cardan CV H Yokes

Chevrolet K5 Blazer Double cardan cv h yokes

Starting at $97.95, AutoBuffy stocks 1 Double Cardan CV H Yokes from MOOG for the Chevrolet K5 Blazer. This heavy-duty U-joint assembly sits at the front of the driveshaft, canceling driveline angles to deliver smooth, vibration-free power transfer. When it wears out, expect clunking, shudder, and accelerated driveline damage if left unaddressed.

Signs your Chevrolet K5 Blazer needs a new Double Cardan CV H Yoke

  • Noticeable vibration through the floorboard or seat at highway speeds, especially under acceleration or deceleration
  • Loud clunk or thud when shifting from Park into Drive or Reverse, felt through the drivetrain
  • Rhythmic shudder that increases with vehicle speed and disappears at a steady cruise
  • Visible grease thrown outward around the front driveshaft slip yoke area, indicating a torn or dried-out CV boot or failed bearing caps
  • Squeaking or squealing noise during slow-speed turns or when the front axle is at full articulation
  • Looseness or play felt when rotating the driveshaft by hand with the vehicle safely raised and in Neutral

Which Double Cardan CV H Yoke should you buy for your Chevrolet K5 Blazer?

The main decision is between a complete pre-assembled CV yoke unit and a rebuild kit, and whether to match OEM specifications or upgrade for higher load capacity. Application fit matters most here — spline count, yoke series (1310, 1350, etc.), and flange bolt pattern must all match your Chevrolet K5 Blazer's existing driveshaft.

Replacing a Double Cardan CV H Yoke on a Chevrolet K5 Blazer

Advanced⏱ 2–4 hoursFloor jack and jack stands or a vehicle liftBreaker bar and socket set (standard and metric)U-joint press or bench vise with socket adaptersSnap ring pliersTorque wrench

Begin by marking the driveshaft and pinion flange with paint or a scribe so the shaft goes back in the same rotational position, then unbolt the flange and slide the driveshaft out. Press out the old bearing caps using a vise or U-joint press, extract the worn CV yoke assembly, and seat the new unit with fresh caps fully pressed to the snap ring grooves. Reinstall the driveshaft aligned to your reference marks and torque the flange bolts to the specification listed in your Chevrolet K5 Blazer service manual before test-driving at progressively higher speeds to confirm vibration is gone.

Frequently asked questions

How much does it cost to replace Double Cardan CV H Yokes on a Chevrolet K5 Blazer?
Parts start at $97.95 on AutoBuffy for the Chevrolet K5 Blazer. A complete DIY replacement using a pre-assembled unit is typically the most cost-effective route. Shop labor, if needed, generally adds one to two hours of billed time on top of the part cost, depending on driveshaft accessibility.
What is a Double Cardan CV H Yoke and how does it work?
A Double Cardan CV H Yoke is a constant-velocity joint assembly that uses two standard U-joints and a centering ball socket to cancel out the speed fluctuations produced at steep driveline angles. The result is smooth, pulse-free torque delivery regardless of suspension droop or lift, which is especially critical on solid-axle trucks and SUVs.
Can I drive my Chevrolet K5 Blazer with a worn Double Cardan CV H Yoke?
You can drive short distances, but it is not recommended. A failing CV H Yoke causes vibration that accelerates wear on the transmission output shaft, slip yoke, and pinion bearings. Complete joint failure can drop the driveshaft, creating a dangerous road hazard. Address shudder or clunking symptoms promptly to avoid compounding repair costs.
How long does a Double Cardan CV H Yoke last on a Chevrolet K5 Blazer?
Service life varies widely based on use. On a stock, highway-driven vehicle, the joint can last many years without issue. Vehicles that are lifted, frequently off-roaded, or used for heavy towing put more stress on the centering ball and bearing caps, shortening service intervals considerably. Periodic inspection and regreasing extend life on greaseable designs.
Is a Double Cardan CV H Yoke the same as a regular U-joint?
No. A standard U-joint operates at a single pivot point and produces cyclic speed variation at angles greater than a few degrees. A Double Cardan assembly uses two U-joints phased together around a centering socket, which mathematically cancels that variation. This makes it the correct choice for applications with steep, consistent operating angles, such as lifted 4x4s.
Do I need to balance the driveshaft after replacing the CV H Yoke on my Chevrolet K5 Blazer?
In most cases, yes. Any time the front driveshaft is removed or a major joint is replaced, having the driveshaft balanced is good practice to eliminate residual vibration. If you are installing a direct OEM-replacement unit and reinstalling the shaft in the same orientation, some owners skip balancing, but a shop balance ensures the smoothest result.
