Before you order
- Match the full catalogue number 5557-2303075 against your vehicle's parts book or the old part — suffixes matter.
- Gears and splined parts wear in as matched sets — mixing worn and new parts shortens the life of both.
- Check mating parts (bearings, washers, seals) at the same time; they usually share the failure.
- For wholesale orders, these parts ship most efficiently as mixed pallets combined with other items.
