Installation Notes and Tips

Verify shaft diameter, housing bore, and seal orientation before installation. The listed fitment includes left-side applications, so confirm the transmission side and model-specific notes, especially on vehicles with transmission codes such as Honda SLXA, BMXA, S4RA, B4RA, M4RA, B46A, AM-1, AK2, AD, AE, AF, AB, and AC. Clean the bore and shaft surface thoroughly, and inspect for wear or scoring that could affect sealing performance.
