Subject: [alfa] ALFADIGEST - 105 GTV front wishbone bushes
Greetings all,
Finally started on refurbishing the suspension of my 1750 GTV. Have
dismantled most of the front left side, so that the only items still on
the
car are the two halves of the lower wishbone (A-arm for our USA friends,
is
it?). I've removed the lower ball joint so the two legs of the wishbone
are
free to be moved around separately. My query is, can I assess the
condition
of the inner bushes while the arms are still on their pivots on the car
body? I don't want to dismantle and rebuild these pivots if there's
nothing
wrong with them.
They seem OK to me so far, but I don't know exactly what to look for when
checking these assemblies. Here's what I've done so far (separately on
each
half of the wishbone):
- - Swung each arm up and down around the range of its pivot, and
confirmed
movement is completely smooth and even, and with what I feel is a nice
gentle amount of friction (i.e. not at all sloppy but not overly tight).
- - Grabbed the outer end of each arm and confirmed no detectable free
play
when pushing in and pulling out at right angles to the pivot.
- - Holding the outer end of each arm, moved the end gently from side to
side,
to apply a rocking movement to the pivot. In this test, there was some
free
play in the pivots, allowing the arms to swing about ten degrees either
way
from their natural rest position.
Any advice or comments please?
Many thanks,
Graham Hilder,
NZ (GTV, 156, Alfasud ti and Sprint).

I used the methods described in that link. The results are good. Not
concours great but it is good for a 'driver' car. There are reports the
cracks will eventually re-appear in about a year or so. I put a dash cover
(carpet type material) on after the repair was cured to minimize the
sun/UV
exposure.
There are some before & after photos of the dash from our GTV6 here:

After I finished the job someone else posted that 'Plastic Dip' makes a
spray product that might also prove useful for dash repairs. I think the
spray-can truck bed liner is a little too thin. If/when I re-do the dash I
might either try the Plastic Dip product or take the dash to a shop that
does spray on truck bed liners (thinking perhaps their material is a
little
thicker/more durable?).

Jon,
Try this, its complicated but the end result appears to be perfect

For $150 you can have the best repair guy in town do the work. I had it
done
on
a an earlier GTV-6. The repair was not visible and it lasted for several
years
- - was still good when I sold the car (which wom a national first with
99+
points.) Just go to the hi dollar new car dealer in town (Porsche,
Mercedes.)
Find out who does their work on their used cars. He'll come to
your house, and
in a couple of hours you wouldn't know there was anything
wrong with your dash.

This is an interesting web site, it doesn't list the Berlina or GTV
but it list the '71 Spider at .380cd and a '90 Spider at .410cd -I
guess that big rubber spoiler was just there for "looks"!

Where does one find aerodynamic numbers for the 105 cars? I
remember doing
a drag coefficient calculation one my '71 GTV using information
provided in
Road & Track based on generic design components, like windshield
size, front
fender to hood shape, rear end shape, etc. I apparently never wrote
the
number I "calculated" down as I haven't seen it in any of my
documentation
in years. It came out in the .3X area and I remember it being
lower than I
was expecting it to be. But of course this was using my
interpretations of
the listed shapes and sizes and doing the calculations so it was a
plausible
number but not experimentally derived.
