Detailed Description

The SKF WKH7048 is engineered as a front hub assembly for Mercedes-Benz S-Class and Maybach S-Class vehicles. Its hub kit design, tone ring, and carefully controlled flange and pilot dimensions support accurate wheel mounting and bearing service. The spindle nut locking system uses two high-strength lock bolts and a precision lock washer to help fine-tune end-play during service. This part cross-references Monroe Shocks & Struts (e.g., 2223340306) for the same application.

SKF WKH7048 is a practical replacement choice for Mercedes-Benz S550, S560, S63 AMG, S65 AMG, S450, and Maybach S550/Maybach S560 front hub service where the original assembly uses this configuration.

What It Is Used For

• Replacing a worn or noisy front wheel hub assembly.
• Restoring proper wheel bearing support and rotation.
• Addressing ABS signal issues related to the tone ring.
