Hi Jerry,
The 3 new GMB u-joints I bought 20 years ago (not installed yet) don't look
so good.
Compared to Spicer or GKN - GMBs seem iffy.
But my question now is; how can I tell what I really have before me!?!
This brand new Hardy Spicer u-joint has 'GKN' cast into the body (it came new
in a Spicer box but the Spicer box DOES have a small GKN logo printed on it).
[merger I suppose]
Why does my nos GKN boxed u-joint have no markings?
And one GMB boxed u-joint with no markings either.
But two GMB boxed u-joints, bodies unmarked, but 'caps' that read U.S.A. -
all three GMB boxes read 'Made in Japan'!
In summary it appears that Spicer and GNK u-joints are of highest quality and
the GMBs have questionable caps.
But does anyone really know how to identify an authentic Spicer, GKN or GMB
u-joint?
Jerry - what identifying marks are cast into your GMBs?
Regards,
Carl

Does anyone else have first hand experience with the GMB joints.
Thanks,
