Do I need to replace all four hubs at once, or can I do front only?

You can replace front or rear independently. Most buyers do all four for consistency, but if one corner is failing and the others are solid, swap just that side.

Will these hubs work with aftermarket wheels or lifted suspensions?

These are engineered for stock 4WD geometry. If you're running a lift or significantly larger wheels, test-fit before committing to installation—bearing preload and ABS sensor clearance may be affected.

What tools do I need to install these, and does anything come with hardware?

You'll need basic hand tools, a socket set, and likely a hub bearing puller or press to remove the old units cleanly. These assemblies do not include fasteners or spindle bolts—use OEM hardware or equivalent when reassembling.
