LÖBRO CV joint (300838) transmits drive torque through full suspension travel and steering lock without generating vibration or noise, using a hardened-steel ball-and-cage design packed with high-temperature lithium-complex grease. Joint specification — Length [mm]: 450 mm, Bore Diameter [mm]: Carbon, 20 mm, Internal Toothing differential side, conn. to conn. shaft: 30, Number of bores: Plastic — determines the operating angle range and torque rating required to handle both the engine's peak output and the lateral forces generated in tight cornering manoeuvres. Spline count, joint diameter, and boot clamp positions are sized for the driveshaft on AUDI, VW applications; the included gaiter and grease pack mean no additional parts are needed for installation. Cross-references OE driveshaft references: 17-0751, 1H0 407 417, 1H0407417, 22933 and 1 more. LÖBRO CV joints are heat-treated and individually inspected for spline geometry before dispatch, matching the articulation angles and service life of the original manufacturer component. CV joints can last the lifetime of the vehicle if the protective rubber gaiter remains intact — but once the boot splits and grease escapes, the exposed joint deteriorates rapidly and typically fails within a few thousand miles. The classic warning sign is a rhythmic clicking or knocking noise when turning at low speed (especially in full lock), caused by worn ball tracks in the outer CV joint — inner joints tend to produce a clunking or vibration under acceleration. CV joint replacement is a moderate-to-advanced DIY job requiring a hub puller or slide hammer, circlip pliers, and a torque wrench — outer joints can often be replaced without removing the entire driveshaft, saving considerable time. When selecting a CV joint, ensure the spline count and ABS ring tooth count match the original — an incorrect ABS ring will trigger traction control and stability system faults. Replacing a worn CV joint promptly avoids the risk of sudden driveshaft failure — a seized or broken joint can lock a wheel while driving, creating a serious safety hazard.
