Buying Guide
Key considerations for steering gear shaft seal purchases include fitment, kit contents, and installation practicality. Ensure the kit matches your vehicle’s steering gear model, year, and make. Look for:
- Comprehensive contents: A full seal kit that includes sector shaft seals, O-rings, dust boots, and vent plugs can reduce the need for extra parts.
- Model compatibility: Confirm that the kit explicitly lists your vehicle models or gear assembly numbers (e.g., Sheppard M90/M100, Pitman shaft seals for Pitman arms).
- Quality of materials: Look for durable seals and boots made to resist wear and leakage under normal steering loads.
- Installation aids: Foam applicators or similar tools can simplify the process and keep residue away from seals during installation.
- OEM vs aftermarket: OEM-recommended parts often ensure better fit and longevity for critical steering components; aftermarket options vary in compatibility.
