SPLINES people! SPLINES!!
But you can do that real easy with Fergy's write-up.
You do not have to have the dealer perform scheduled maintenance as long as you keep the records and receipts from you doing the job yourself.
One additional thing is to check over all of your connections and bolts.
Clean and repack connections, make sure bolts, motor mounts, cable connectors are tight and torqued to specs.
