E-cowlboy Universal Joint Puller & Bearing Cup Installer Kit — Black, 1.5–2.2" Cups, Heavy-Duty for Class 6–8

The E-cowlboy 10102 heavy-duty universal joint puller combined with the 5192 bearing cup installer is a professional two-piece kit designed to remove and install 1.5"–2.2" U-joint bearing cups on Class 6–8 drivelines quickly and without damage.

This kit pairs a brute-force puller with a precision installer so diesel techs, fleet mechanics and heavy-equipment technicians can handle seized universal joints and bolt-retained bearing cups found on Spicer and Meritor drivelines. Built from hardened carbon steel with a black protective finish, the set is sized for common truck series and intended to shorten downtime while preserving yokes, driveshafts and cups.

How does the 10102 puller remove stuck bearing cups?

The 10102 uses a high-torque puller body that accepts up to a 1" impact wrench to deliver concentrated force straight onto the bearing cup. Its geometry centers on the joint so extraction happens rapidly and cleanly without bending the yoke.

• Works with 1.5"–2.2" bearing cups
• Compatible with most Class 7 and 8 U-joints (Spicer/Meritor series)
• Designed to avoid contact damage to driveshafts and yokes
• Use of impact wrench speeds removal of seized cups

What makes the 5192 installer reliable for bearing cup installation?

The 5192 bearing cup installer aligns and drives bolt-retained cups evenly into the yoke bore, preventing cocking and misalignment. Its contact surfaces are shaped to guide the cup squarely, so you get proper seating without hammering or improvised tools.

• Automatically aligns cups during installation
• Fits series 1610 through 1880 and many bolt-retained U-joints
• Reduces risk of cup tilt and premature wear
• Speeds reinstall during service intervals or axle repairs

Is the kit durable enough for daily shop use?

Yes — both tools are manufactured from premium-grade heavy carbon steel and finished with a black corrosion-resistant coating. The materials and heat-treated surfaces are chosen for repeated impact and torque, extending service life in commercial environments.

• Hardened carbon steel construction for longevity
• Black anodized/finished surface for corrosion resistance
• Precision-machined contact areas to maintain fit over time
• Backed by a 12-month warranty and 30-day returns

Which drivelines and bearing series does this set support?

This two-piece set covers a wide range of heavy-duty truck and machinery U-joints used in freight and vocational fleets. It was engineered to fit Spicer and Meritor (Rockwell) families and many common truck driveline models so you can standardize one toolset for multiple vehicle types.

• Spicer drivelines: 1610, 1710, 1760, 1810, 1880
• Meritor (Rockwell): 16N, 17N, 18N, 1710 series

Who is this for? The E-cowlboy 10102 & 5192 kit is built for professional technicians, fleet maintenance teams and serious DIYers who service Class 6–8 trucks, heavy trailers and industrial machinery. If you routinely remove seized U-joints or reinstall bolt-retained bearing cups and need a durable, repeatable method that protects yokes and driveshafts, this kit reduces labor time and risk compared with makeshift methods.

The product comes with customer support, a 30-day satisfaction return window and a 12-month warranty to help keep your shop moving. Always follow vehicle manufacturer procedures and safety practices when using impact tools and service equipment.
