3102-2201025 UJ3110 3088 Universal Joint 30×55×88 mm | GAZ UAZ BJ212
Description
3102-2201025 universal joint is a greaseable inside-circlip cross bearing for selected GAZ, UAZ, Volga, Gazelle and dimension-matched BJ212 driveline applications. Its identifying measurements are a 30 mm bearing-cup diameter, 55 mm distance between the inner retaining faces and 88 mm total cup-to-cup span. All three values must be checked together.
The photographed 3102-2201025 universal joint is supplied as one assembled cross with four bearing cups and four bent-tab internal retaining rings. The rings fit inside the yoke bores after the cups are pressed into place. This retention method differs from common external-circlip joints, even when the cup diameter appears similar.

Applications and Cross-Reference
The 3102-2201025 universal joint is commonly associated with Russian and CIS vehicle driveline service, including selected GAZ, UAZ, Volga and Gazelle propeller shafts. It can also be evaluated for BJ212 shafts that use the stated dimensions and internal-ring arrangement. Browse our Russian vehicle universal joint range for related sizes.
Do not identify the 3102-2201025 universal joint by vehicle name alone. Shaft production changes, replacement yokes and regional variants can alter the required joint. A 30×55.1×85 mm GUM-93 or MB000267 joint is a different size and should not be substituted merely because its cup diameter is close.
How to Verify Fitment
Before ordering a 3102-2201025 universal joint, measure one cup with a caliper. Then measure 55 mm between the inner circlip seating faces and confirm the complete 88 mm span across the opposing cup ends. Compare the ring-groove position, cup shoulder, seal profile and grease-fitting clearance with the removed part.
During installation, clean the yoke bores and inspect them for distortion. Press each cup evenly so the needle rollers remain upright, install all four retaining rings completely, and check that the cross moves freely without binding or unwanted axial play. Apply the lubricant and service interval specified for the shaft.
