Frequently Asked Questions
Q: What components are included in the SU S898-XL-A assembly?
A: The SU S898-XL-A includes the 3.25 inch diameter x 5.625 inch width load wheel, installed bearings, and the axle mounting hardware. This is a ready-to-install unit. Do not separate components unless the bearing or hardware requires individual replacement.
Q: Is the SU S898-XL-A a plug-and-play replacement?
A: Yes, if your axle shaft bore diameter matches 2.0467 inches and your truck mounting width accommodates 5.625 inch side-to-side width. Remove the old assembly by unbolting the retaining hardware, slide the new assembly onto the axle, align it with mounting holes, and torque fasteners to specification per your truck manual. If axle dimensions or truck frame configuration differ, the assembly will not fit.
Q: Can I use just the wheel from the SU S898-XL-A assembly on my existing axle?
A: Only if your existing assembly has compatible bearings and axle hardware. The wheel itself (SU S898-XL) can be separated and reinstalled if bearings are still serviceable. However, if bearings show grinding, excessive play, or discoloration when you remove the old wheel, install the complete new assembly SU S898-XL-A instead to avoid bearing failure.
Q: What is the lifespan of bearings in the SU S898-XL-A assembly?
A: Bearing life depends on operating conditions. Under moderate use, bearings typically last 18 to 24 months. Under heavy continuous load or wet environments, lifespan may drop to 12 months or less. Inspect bearings monthly by spinning the wheel by hand. If rotation feels rough or you hear grinding, replace the assembly immediately to prevent axle damage.
Q: How do I diagnose a failed bearing in the SU S898-XL-A assembly?
A: Symptoms include squeaking or grinding noise when the truck moves, visible heat or discoloration on the wheel hub, the wheel is difficult to spin by hand or stops abruptly, or the wheel wobbles side to side when you push on it. If any of these occur, stop using the truck immediately. Replace the complete assembly SU S898-XL-A to prevent axle shaft damage and loss of truck control.
