OEMTOOLS Heavy Duty U‑Joint Puller for Semi Trucks — Class 7‑8, 1.5"–2.2" Cup Capacity, 1" Drive Compatible

The OEMTOOLS 24538 Heavy Duty U‑Joint Puller safely extracts seized U‑joint bearing cups on Class 7–8 trucks without hammering or heat, preserving yokes and driveshafts.

When you work on heavy‑duty drivelines, a tool that removes U‑joint cups cleanly and predictably saves time and prevents costly part damage. The OEMTOOLS 24538 is built for pro shops and experienced DIYers who service Class 7 and 8 vehicles; its design accepts bearing cup outer diameters from 1.5" to 2.2" and uses a controlled 1" drive impact or smaller for steady, mechanical extraction. That combination of capacity and control lets you avoid improvising with hammers, chisels, or heat.

How does this puller remove seized U‑joint cups without harming the driveshaft?

The tool uses a forcing screw design and supporting fixtures that push the bearing cup straight out of the yoke, concentrating force on the cup rather than on surrounding components. Because the puller guides the cup along a consistent axis, there’s minimal lateral stress on the yoke or driveshaft flange.

• Forcing screw applies smooth, centered pressure to the cup.
• Support fixtures hold the yoke steady to prevent twisting or bending.
• Compatible with impact or breaker wrench up to 1" drive for controlled torque.

What bearing sizes and truck classes will this tool fit?

This puller covers a wide range of heavy‑duty U‑joint cups, accommodating cup outer diameters from 1.5" (38 mm) up to 2.2" (56 mm). It’s specifically engineered for Class 7 and Class 8 drivelines, which are common on heavy trucks and vocational vehicles.

• Fits bearing cup OD range: 1.5" to 2.2" (38–56 mm).
• Intended for Class 7–8 truck U‑joints and similar heavy duty applications.
• Universal fit for most OEM and aftermarket heavy truck U‑joint cups.

What tools do I need to use this U‑joint puller effectively?

Use a 1" drive impact wrench or a smaller drive impact/breaker to operate the forcing screw; the puller is not designed for larger pneumatic guns that exceed recommended torque. Basic supporting tools—such as a jack or stands to stabilize the driveline and standard sockets to mount the puller—complete the setup.

• 1" drive impact wrench or smaller for controlled removal.
• Vehicle support (jack stands or lift) to access the driveshaft safely.
• Common sockets and wrenches to position and secure the puller.

Will this prevent the need for heat or makeshift removal methods?

Yes—by delivering controlled axial force, the puller gets seized cups out without resorting to heating, striking, or improvised levers that can damage parts. That keeps yokes, seals, and driveshaft surfaces intact and reduces post‑removal repairs.

• Eliminates hammering that can deform yokes or shafts.
• Avoids heating that risks bearing or seal damage.
• Reduces the chance of replacing additional driveline components after removal.

Who is this for: The OEMTOOLS 24538 is aimed at professional heavy‑truck technicians, fleet maintenance teams, and skilled DIY mechanics who regularly service Class 7–8 vehicles and need a reliable, repeatable method to remove U‑joint bearing cups. If you value preserving driveline components, minimizing downtime, and using a tool built for heavy duty workloads, this puller will integrate into a shop or mobile service kit and deliver predictable performance on stubborn U‑joint jobs.
