Allan,
Let me relieve your confused state of mind. The problem you
are experiencing with your muffler bearings is due to a
compound misunderstanding of their purpose and correct
fitment.
Firstly, the "muffler bearings" are a simple layman's term
for the more correct description, "exhaust extractor
differential rotation harmonic equalizer". Part of this
system is, what might loosely be described as four "muffler
bearings", two on each side of the car. They are actually
located before and after each exhaust 'silencer',
surrounding the tubes on each side of the 'silencers'.
Secondly, the remainder of the system consists of balance
bars and "Z" linkages with Heim Joint ends, connecting the
outer shell of the bearings, athwart ship. Similar, but
opposite linkages are at the rear.
In practice, when the flow on one side of the engine is
pulsating out-of-phase with the other, the rotational
exhaust flow tends to twist the exhaust system in opposite
directions. The "Z" linkages, through the balance bars,
correct the imbalance and minimize disturbing exhaust
loudness. Friction dampers are fitted to the later systems.
Many owners have decided to forgo the correct replacement of
these components, when worn. This can result in excess
exhaust noise on acceleration, most disturbing in the
English countryside. Many Tigers exhaust sounds can be
heard above the surrounding sedan traffic.
A sure give-a-way to improper maintenance.
Additionally, the unbalance of these forces can cause
excessive loads on the driver's seat frame and upholstery,
causing excessive forces on the hide covers. Premature
failure can result.
Are you sufficiently enlightened?
Steve
