Choosing the right heavy-duty truck yokes and U-joints starts with identifying your drivetrain components. Whether you operate a Freightliner, Kenworth, Peterbilt or Mack, the replacement must match your truck’s specific configuration.
This guide explains the difference between driveshaft yokes and universal joints, how to check replacement references, and where to find relevant heavy-duty truck parts at Saen Export Truck Parts.
What Is the Difference Between a Yoke and a U-Joint?
A driveshaft yoke forms part of the connection within the drivetrain assembly. Depending on its location and design, it may be an end yoke, a tube weld yoke or another type of driveshaft connection.
A universal joint, also called a U-joint or driveshaft cross, allows rotational motion to transfer between driveline sections operating at different angles. Yokes and U-joints work together, but they are different components and must be matched to the requirements of the assembly.
How to Choose Heavy-Duty Truck Yokes and U-Joints
Start with the original component’s part number. Compare that reference with the replacement and cross-references listed on the product page. A similar appearance does not establish fitment.
Next, confirm the drivetrain series. Our Yokes & U-Joints collection includes components identified with series such as 1710, 1760, 1810, SPL170, SPL250, 20R and 25R. These designations should not be treated as interchangeable.
For a yoke, check the design, spline diameter, spline count, overall length and connection dimensions. For a U-joint, compare bearing cap dimensions, overall measurements and retention style. Use the component manufacturer’s specifications or ask a qualified drivetrain technician if identification is uncertain.
Yokes and U-Joints for Freightliner, Kenworth, Peterbilt and Mack Repairs
The truck brand is only the starting point. Freightliner, Kenworth, Peterbilt and Mack trucks can have different drivetrain configurations. Do not assume a replacement fits solely because your truck brand is mentioned.
Confirm the installed component’s part number, series and measurements before ordering. The references below are examples from our collection, not a guarantee of compatibility with every model.

Use these product pages to compare specifications against the original component. A shared series name alone is not enough to confirm fitment.
Frequently Asked Questions About Truck Yokes and U-Joints
How do I identify my truck’s U-joint series?
Start with the part number or markings on the existing component and check the manufacturer’s information. If the reference is unreadable, compare the bearing cap measurements, overall dimensions and retention style with verified specifications. Do not identify the series by appearance alone.
Are 1710, 1760, 1810 and SPL250 U-joints interchangeable?
Do not treat these series as interchangeable. Select the replacement specified for the assembly and confirm its dimensions and mounting design. If a substitution is proposed, have it verified by the component manufacturer or a qualified drivetrain specialist.
Can I select a yoke or U-joint using only my truck’s brand?
No. Freightliner, Kenworth, Peterbilt or Mack branding alone does not establish compatibility. Confirm the installed drivetrain component’s reference, series and dimensions.
What information should I have before ordering a replacement yoke?
Have the original part number, yoke type, spline diameter and count, overall length and connection measurements available. Compare them with the product specifications before ordering.
Does replacing a U-joint mean I also need a new yoke?
Not automatically. Have the assembly inspected for wear or damage and follow the manufacturer’s service guidance. A qualified technician can determine which components require replacement.
