Remove the hub and bearing assembly and backing plate from the knuckle.
11.
Place the hub and bearing assembly on a suitable work surface with the lug nut studs facing down.
12.
Using a flat bladed tool (e.g., gasket scraper or stiff putty knife) and mallet, carefully pry the edge of the dust cap up from the hub. Continue
working your way around the dust cap until it disengages from the hub.
13.
Remove the dust cap and inspect for the presence of a spanner nut (1) on the threaded shaft.
^
If hub and bearing assembly HAS the spanner nut (1), then proceed to the next step and install a new dust cap.
^
If a hub and bearing assembly DOES NOT have the spanner nut (2), then the hub and bearing assembly must be replaced. Replacement hub
and bearing assemblies do NOT need to be inspected. Therefore, do NOT remove the dust cap on a replacement assembly. Proceed to Step 15
after obtaining a new hub and bearing assembly.
