Slowly rotate the spindle and observe the dial indicator’s reading. Excessive runout can indicate a bent or warped spindle.
5. Brake Component Alignment: Check the alignment of the brake components, including the brake rotor and caliper, in relation to the spindle. Ensure that the rotor sits flush against the spindle surface and that the caliper is properly aligned with the rotor. Misalignment can indicate a bent or damaged spindle.
6. Seal and Bearing Inspection: If possible, remove the wheel bearing and seal to inspect them for any signs of damage, wear, or leakage. Look for pitting, excessive wear, or damaged seals. Replace the bearings and seals if necessary.

It’s important to note that axle spindle inspection may require specialized tools, such as a dial indicator or bearing puller. If you’re uncomfortable performing the inspection yourself or lack the necessary tools, it’s recommended to have a qualified mechanic or technician inspect the spindle for you.

Regular axle spindle inspections can help identify potential issues early on, allowing for timely repairs or replacements. If you notice any signs of wear, damage, or irregularities during the inspection, it’s advisable to consult a professional for further evaluation and necessary repairs.

In summary, properly inspecting an axle spindle involves a visual and tactile examination for signs of wear or damage, checking for bearing play, measuring runout, assessing brake component alignment, and inspecting the wheel bearings and seals. Follow the recommended steps and consider seeking professional assistance if needed.
