The old dog bone (torque strut) had been on my '84
Fiero since I bought it in April of '84; neither it
nor its two rubber bushings had ever been replaced.
For those of you unfamiliar with this part, it
anchors the engine to the rear frame of the Fiero
and keeps it from moving excessively during
When I started hearing a
"clunk" from the rear of the car this past July, I
was afraid it was loose half-shaft U-joints, as used
to happen with the independent rear suspension on my
old Triumph TR6. But I decided to go with what
seemed like the simplest solution first, and change
the dog bone.
After talking to other Fiero
owners and reading about the problems they were
having with engines shifting out of position and
having to be forced back into place with a crowbar.
There is also an ongoing debate among owners of
automatic transmission cars over rubber versus
harder polyurethane (poly) bushings. I started to
get a little worried. I'm no expert; I'm a shadetree
mechanic, without an impact wrench to my name.
Socket wrenches, crescent wrenches and breaker bars,
So I was surprised how easy it was
to loosen the two nuts and bolts holding it in, and
really relieved when the engine never even budged. A
little hammering and massaging of the metal brackets
on the engine and frame, and the new, slightly wider
dogbone ($12 bucks on Amazon) went right in. No
I was also surprised at
the inferior design of the rubber bushings on the
original dogbone; there were gaps between rubber and
metal on either side of the round holes they were
pressed into. On the side where it was bolted to the
engine, the bushing had two major cracks, and was so
worn that the center metal liner easily slid in and
out. That's definitely not supposed to happen;
probably the main source of the "clunk".
Anyway, I'm looking forward to driving my now "clunkless"
Fiero for many years to come. It's almost like a
