RE: Lower A arm nuts

["Jeff Greenfield" <alfaguy@xxxxxxxxxx>]

Jon - 

I just checked some of my manuals ... you are right in that the mid 80s
factory shop manual omits this spec.

I did find it in two others though, a late (series 4) factory manual says:
"Screws securing rod pins to lower wishbone arms, 35.4 thru 39.1 (ft-lbs)"

Another much older autobooks 1750/2000 manual states: "Lower wishbone shaft
to crossmember, 40.5 - 42.7 ft-lbs", but now that I'm thinking about it,
this seems to be for the bolts that hold the assembly to the body and these
numbers appear to be pretty much the same as that spec in the factory
manual.

Funny, I don't remember having any trouble finding this when actually doing
the job in the past.

You could always go with a generic spec for the size and pitch of the
fastener, I'd look that up but I don't remember what size they are ...

HTH,

Jeff

Hey Jeff..

Wondering what your manual is, and says?  I have a very old (printed in 
71) 2L tech spec, it's very unclear as to the names of the parts and the 
one that makes most sense is only 40-50 ft-lbs..  a borrowed 80's 
factory shop manual, which has everything EXCEPT the lower A bush nut 
torque spec.. (apparently left out!) and an old Kenneth Ball (Brit 
pubication) Autobook for Gulias up to early 70's, and it says "90 -130 
ft-lbs".

Kinda wishing I had more than one source saying the same thing, after 
all that confusion..  though I could believe the 90 or so..  90 to 130 
is a wierdly large spread! I just don't want to overtorque it.
