Installation Notes and Tips

Verify the shaft and housing dimensions before installation, and compare the old seal to the new Elring 843.680 for diameter, height, and lip design. Clean the sealing bore thoroughly, inspect the shaft surface for scoring, and install the seal squarely to avoid distortion. For Porsche 911 applications, confirm the differential service position and match the seal to the original AS2W-style profile.
