E-cowlboy Universal Joint Puller & Bearing Cup Installer Kit Black — 1.5–2.2in for Class 6–8, Heat‑Treated Steel

E-cowlboy's 10102/5192 kit is a heavy-duty universal joint puller and bearing cup installer designed to remove and install 1.5"–2.2" bearing cups on Class 6–8 trucks and heavy machinery without harming yokes or shafts.

This two-piece professional toolset pairs a brute-force U-joint puller with a precise bearing cup installer so diesel techs, fleet mechanics, and equipment shops can tackle stubborn universal joints quickly. Built from heat-treated carbon steel with a black anodized finish, the tools resist corrosion and deliver repeatable performance across common Spicer and Meritor driveline series. The kit is engineered to work with widely used bolt-retained bearing cups and fits most heavy-duty truck applications.

How does the 10102 puller remove seized universal joint bearing cups?

The 10102 is made to accept a one-inch impact wrench and translates that torque into a straight, controlled extraction force so frozen bearing cups come out without hammering the yoke. Its geometry centers the pull, minimizing bending forces that could deform the driveshaft or yoke.

• Works with bearing cups from 1.5" to 2.2"
• Compatible with one-inch impact wrench for high torque removal
• Designed to protect driveshaft, yokes, and joints
• Quick extraction on heavily corroded or press-fit cups

What makes the 5192 bearing cup installer precise and reliable?

The 5192 automatically aligns bolt-retained bearing cups as you press them into place, eliminating guesswork and reducing rework. It controls seating depth and force so cups go in squarely, protecting needle bearings and ensuring correct joint preload.

• Self-aligning design for bolt-retained universal joints
• Fits Spicer and Meritor series 1610–1880 and many others
• Prevents misalignment that can shorten joint life
• Smooth, controlled installation that saves labor time
