[6pack] Low Frequency Shimmy

[brian at asmoothmove.biz]

Vance:

Yes, when I restored the car 6 years ago, I tore them down, de-greased them
and liberally covered the splines with grease upon re-assembly. I remember
noting that there was play when I put them back together, but had no way of
determining how much. Because of the constant clunking when starting out and
changing gears I guess there was too much play and they were just plain worn
out. The splines still had plenty of fresh grease in them when I removed
them recently. The new axles have zerk fittings to facilitate keeping the
splines lubricated. I don't recall the originals having zerks.

    Interesting. Had the axles been regreased during the frame off?

    The reason I ask is that the axles have a reputation for binding as the
grease dries out. I tore mine down and cleaned and regreased mine. The
grease had completely dried out and was like paraffin (That would be kitchen
wax to our friends on the other side of the pond) rather than grease. While
paraffin has lubricating properties, it is nothing like grease. So a handful
of axle grease was used on both, and new boots then they were reinstalled.

     My point is, could your axles have been binding, or were they truly
worn out (or perhaps both I suppose)?

	Cheers,

    Apparently, the old axles must have wobbled or vibrated at a resonance
that manifested itself as the shimmy. With the new sliding axles, the shimmy
is gone. I would be interested to hear if anyone else has had similar
results.
