Detailed Description

Use Beck Arnley 052-3749 when replacing a worn or leaking differential seal on select Toyota trucks and SUVs. The seal dimensions are specified to support proper seating in the housing bore and consistent contact at the shaft, which is important for maintaining a clean sealing surface in the differential cover area.

What It Helps Fix

• Differential fluid seepage at the right-side seal
• Leakage caused by a hardened or worn sealing lip
• Improper sealing from an incorrect housing bore or shaft size
• Service issues after differential cover or axle-side seal replacement
• Contamination risk from a compromised differential seal

Installation Notes and Tips

Confirm the housing bore, shaft diameter, and right-side application before installation. Clean the sealing surface thoroughly and inspect the shaft and bore for wear, scoring, or debris that could affect seal life. Proper alignment during installation helps the side lip seat evenly and reduces the chance of early leakage.
