Frequently Asked Questions
Q: What is the difference between the SU S524 and SU S524-A?
A: Both have the same 3.375 x 3.97 inch wheel dimensions. The SU S524-A is a complete pre-assembled unit with bearing and hub already installed. The SU S524 is the wheel only. Choose the SU S524-A if you want a faster installation and do not have bearing installation equipment. Choose the SU S524 if you have in-house bearing service or your axle already has ready-to-install hubs.
Q: Can I use the SU S524-A assembly if my truck originally came with a different wheel size?
A: No. The SU S524-A assembly is designed for trucks that originally specified a 3.375 x 3.97 inch wheel. Changing wheel size alters steering response, load distribution, and may overload the axle. Always verify your truck model and serial number against the OEM spec sheet before purchasing. Using an incorrect wheel size can void your truck warranty and create safety hazards.
Q: Does the SU S524-A assembly come with installation instructions and hardware?
A: The assembly includes the wheel, bearing, and hub. Hardware such as cotter pins, snap rings, and axle clips are typically not included because truck designs vary. Refer to your truck service manual for the correct fasteners and installation sequence. If you do not have the manual, contact your lift truck dealer to obtain the correct parts and procedures before installation.
