Vibration @ 50 mph

Where does the return spring for the parking brake linkage go on a 54-3100 ?
I don't see it in the book. On the cross-frame bar ?
Thanks

Well, as maybe suspected .... both primary shoes were on one side, and both secondary on the other. Landing pads are pretty groovy and the contamination from the rear was a bit worse than initially observed.
New seals and shoes on the wayyyyyyyy.

Now the return springs ... pri and sec look identical, same color (blue), same wire gauge and all. Were they the same on these models ? I saw no mention in the shop manual of them being different.
Thanks again.

Also, I think the axle seals were installed backwards.
It had the dual lip leather CR seals with the springs to the dry side.
I always thought that the springs go to the wet side.
Which is correct ?
And I'm still trying to determine where the return spring for the parking brake goes ..... anyone have an original setup to help ?
Thanks.

This describes a 54 with a hand brake.. Mine is a foot brake.
The general idea/spec would be the same ?
Thanks dsraven.

And I see no mention of the pullback springs being different on this model. Just says to put the pri on first, then the sec.

All going back together today.

Thanks for the help.
