I am going over the parts around the rear wheel bearings and replacing what is needed.
is there a difference between the 2 part #'s I listed above or are they the same thing.

in the online parts manual they are both listed for my bike.
I'm confused.

BUT the part ending in 770 is no longer available.

parts 4 and 5.
and my bike is a 7L.

thanks.
