VCCA Home Forums TECHNICAL - GENERAL Mechanical - Engine, Trans, etc Different Dubonette (knee action)

Hello all,

I just had a look under the 37' 4 door slant back sedan that I bought a few days ago.

It has 2 different types of arms from the Dubonette suspension unit to the spindle.

Please see attached photos.

One arm has 4 attaching fixings whereas the other has a round disc with many holes around it.

Which is correct for 37 ?

Scroll to page 22.

The 1934 and 1935 has the four bolt type and 1936-1938 the one piece type.
They are interchangable.
Eaxh year from 1935 and up they changed the internal valving of the shock absorber to sriffn the ride.
Some owners thought that they were too soft and bouncy.
