What to consider before buying

When choosing a main shaft seal, ensure compatibility with your vehicle's make, model, and transmission type. OEM seals guarantee fit but cost more; aftermarket options like National or Timken offer good value. Check reviews for installation ease and durability. Avoid cheap no-name seals as they may fail prematurely.
