Loose wheel SP36?

[williamcharrison]

I took the bird out for a test drive after replacing the thermostat
and ran over a rather large pothole at which time I heard (and felt)
a rattling from the right front wheel which felt similar to an episode
I experienced with an old truck I had which turned out to be worn
kingpins. Questions are: does this coach have kingpins and if so
how big a job is it to replace them?
