Frequently Asked Questions
Q: Is the SU STR5213 caster assembly compatible with my Crown or Toyota lift truck?
A: The SU STR5213 is an aftermarket caster assembly. Compatibility depends on your truck frame, axle configuration, and load class. Compare the mounting hole pattern, wheel diameter, wheel width, and load rating to your truck specifications. Many Crown and Toyota models can accept aftermarket casters if dimensions align. Always verify your model year and serial range before purchasing.
Q: What is the difference between the SU STR5213 and OEM caster assemblies?
A: The SU STR5213 is an aftermarket part, meaning it is manufactured by a third party, not the original truck manufacturer. Aftermarket casters typically cost less and offer equivalent performance if dimensions and load rating match the original. OEM parts carry the original manufacturers warranty and specifications. Confirm that SU STR5213 specifications match your truck before installation.
Q: What symptoms indicate that the SU STR5213 caster assembly needs replacement?
A: Replace the caster assembly if you observe: steering wheel resistance or drag, uneven tire wear on the wheel, visible cracks or damage to the wheel, loose or rattling mounting brackets, or bearing play (side-to-side movement when you push the wheel). These symptoms indicate bearing failure, wheel damage, or fastener looseness that compromises truck handling and safety.
Q: How do I install the SU STR5213 caster assembly?
A: Installation is straightforward: (1) Raise the truck on a jack stand for safety. (2) Remove the old caster assembly by unbolting the mounting fasteners. (3) Align the new SU STR5213 mounting holes with the truck frame. (4) Install and torque fasteners according to your truck manual, typically 40-60 foot-pounds depending on bolt size. (5) Lower the truck and test steering response. Do not operate the truck until all fasteners are tight.
