Detailed Description

Beck Arnley 052-3753 is a transfer case output shaft seal engineered for front-position service on 1996-2002 Toyota 4Runner and 1995-2000 Toyota Tacoma models. The seal dimensions, including a 59 mm housing bore, 49 mm shaft diameter, and 15 mm overall width with side lip, are important for maintaining a proper sealing surface at the transfer case output shaft. For buyers searching for a Toyota 4Runner transfer case output shaft seal or a Toyota Tacoma front transfer case seal, this part number provides a focused OE-style replacement option.

Beck Arnley sources parts to meet foreign nameplate OE specifications, helping ensure the part matches the original application’s form and function. This part cross-references National (e.g., 710068, 710069) for the same application.

What It Helps Address

• Transfer case fluid seepage at the output shaft area
• Visible oil residue around the front transfer case seal
• Seal wear from age, heat, and drivetrain movement
• Loss of sealing integrity after service or disassembly
• Noise or contamination concerns caused by low transfer case fluid

Installation Notes and Tips

Verify housing bore and shaft diameter before installation to confirm the seal matches the transfer case opening and output shaft. Inspect the shaft surface for grooves, scoring, or corrosion that could affect sealing performance. Clean the bore and surrounding area thoroughly, and install the seal squarely to avoid distortion of the side lip. Confirm the application is front position only for the listed Toyota 4Runner and Tacoma fitments.
