Lisle U-Joint Puller for 1"–1.25" Bearing Caps — Small, Heat-Treated Threads for Damage-Free Removal

Lisle 42890 small U-joint pullers remove sealed U-joint caps quickly while protecting driveshafts, yokes and bearing caps from damage.

The Lisle 42890 is a compact, professional-grade puller designed for removing sealed universal joint caps from cars, light trucks and agricultural equipment. Built with heat-treated threads and cast components, this tool delivers controlled extraction on 1" to 1.25" bearing caps without marring surrounding surfaces. Two size options accommodate a wide range of applications, making it a practical addition to a mechanic's toolbox or a DIY enthusiast's garage.

How does the Lisle 42890 protect driveshafts and yokes during removal?

Unlike improvised methods that can dent or twist the driveshaft or yoke, the 42890 applies even, concentrated force to the bearing cap so the surrounding metal stays intact. Its contact points are shaped to engage the cap securely, reducing slippage and unintended contact with the yoke.

• Designed to press on bearing caps only, avoiding yoke edges
• Even mechanical force prevents sudden jolts that cause damage
• Heat-treated components maintain shape under pressure for consistent results

What sizes and vehicles will this puller work on?

The Lisle 42890 is sized for sealed U-joint caps between 1" and 1.25" diameter, covering many passenger cars, light-duty trucks and some ag equipment. Two size options in the kit let you match the puller to the cap for a secure fit and effective extraction.

• Fits 1" to 1.25" bearing caps commonly found in light vehicles
• Two-size design broadens compatibility across models
• Vehicle-specific fit depends on your driveshaft/U-joint dimensions

How durable is the tool and what materials are used?

Lisle engineered the 42890 with durability in mind: the threads and cast sections are heat-treated to resist wear and deformation under repeated use. That construction ensures reliable operation in professional shops and home garages over many extraction jobs.

• Heat-treated threads resist stripping under load
• Robust casting maintains alignment and structural integrity
• Manufactured to withstand the forces needed for sealed cap removal

How do I use the puller safely and efficiently?

The tool installs over the bearing cap and uses a threaded forcing screw to push or pull the cap free with controlled pressure. Use correct size, support the driveshaft, and work slow to avoid sudden release; light tapping can help free a stuck cap before applying full turning force.

• Select the matching puller size to the cap diameter
• Support the driveshaft to prevent twisting or bending
• Turn the forcing screw steadily; use penetrating oil if needed

Who is this for: The Lisle 42890 small U-joint pullers are ideal for mechanics, fleet technicians, restoration hobbyists and anyone who services drive lines on cars, light trucks or agricultural machines. If you routinely replace U-joints or need a reliable, non-destructive method to remove sealed caps, this compact, heat-treated puller offers a practical, long-lasting solution.
