Frequently Asked Questions
Q: Is SU 2358-A compatible with SU 2350-A trucks?
A: No. SU 2358-A and SU 2350-A are not interchangeable. They are engineered for different truck models or load classes. Mixing assembly types on the same truck will cause alignment problems and compromise braking. Always replace with the exact part number for your truck.
Q: What bearing configuration does SU 2358-A use?
A: SU 2358-A uses sealed ball bearings matched to the wheel hub and truck axle design. Bearing type and preload differ from SU 2350-A. Verify the specific bearing configuration (2RS, Z, or open) with parts documentation for your truck model before installation.
Q: How do I know if SU 2358-A is the correct replacement for my truck?
A: Locate your truck model and serial number on the manufacturer nameplate. Cross-reference this data with Superior parts catalogs or contact field support with your complete truck information. Do not estimate or guess part numbers. An incorrect assembly will not fit.
Q: What is the typical service life of SU 2358-A?
A: SU 2358-A typically lasts 18 to 36 months under normal warehouse operation. Heavy-duty use, outdoor service, or abrasive floors may reduce lifespan to 12 to 18 months. Sealed bearings require no maintenance but cannot be repaired, only replaced as an assembly.
Q: Does SU 2358-A installation require axle removal?
A: This depends on your truck model. Some trucks allow in-place replacement without axle removal. Others require partial disassembly. Consult your service manual or contact Superior field support with your truck model number for specific installation steps and required tools.
