Windshield wiper motor arm splined bushing

Start by matching the spline size, bore diameter, and overall dimensions to your wiper motor arm. Check the spline count and pitch so the bushing seats correctly on the shaft, and decide between OEM-style reliability or aftermarket options. Read the product specs carefully; in this listing, items come from a generic-brand bushings category, so verify compatibility with your vehicle’s make and wiper system.

The spline interface—count, pitch, and diameter—drives whether the bushing seats correctly on the shaft and prevents play. To verify, compare the vehicle’s wiper shaft spline with the product specs, measure the bore and outer dimensions with calipers, and ensure tolerances align. Material choice matters for durability in varying weather; nylon and bronze bushings offer different wear resistance and may be better for your climate.

A beginner should select a windshield wiper motor arm splined bushing with clear, well-documented specs and a straightforward fit to avoid custom tooling. A professional will take precise measurements (spline count, shaft diameter, bore tolerance), assess high-use conditions, and may prefer bushings with higher wear resistance and load ratings. In both cases, confirm compatibility with your vehicle and the bushings category's generic-brand options.

Keep the splines clean and dry, removing debris before reassembly. When mounting, use correct fasteners and avoid forcing a mismatched bushing onto the shaft. Lubricate only if recommended by the product specs, and regularly inspect for wear or play. Always check that the bushing is compatible with your vehicle’s make and wiper system, and refer to the generic-brand bushings listing for fitment guidance.

Common signs are looseness, wobble, unusual chatter, or misaligned wipes during operation, which point to worn splines or bushing wear. When shopping, verify spline count, bore size, and overall dimensions to match your shaft, and choose a generic-brand bushing from the bushings category that lists compatibility with your vehicle’s wiper system. Avoid guesswork by sticking to items with clear specs and documentation.
