Sudden vibration/noise in the cabin.

Transmission mount shagged!

Place jack under transmission pan to support transmission (use block
of wood between jack and pan to distribute stress on pan).

Remove cross-member (4 bolts, 14mm) and broken mount under rear of
transmission. My mount was so corroded that center bolt (15mm) did
not even need removing.

Remove shagged mount, screw in new mount ($10 aftermarket, $60 from
Volvo)

Replace cross-member/transmission mount assembly.

done.
 
I often read where bolts are hard to undo due to corrosion and panels need
replacing because of rust .We here in Austrlia have no such issues .Our car
wear out but the bodies are fine .My wifes 1988 was running well and the
body fine at 280 000klm. Sold to the first viewer ..My 1990 turbo 740 has no
rust and runs like new but its only done 184000km on synthetic oil so a baby
..
 
You live in a dry climate down under, so it is not surprising that
bodies don't rust easily.

Same here in the SW, e.g. LA.

I live in Pacific NW, and car bodies rarely rust, even though it rains
a lot.

Main cause of rust: salt on roads in winter, e.g. in New England and
Upper Midwest, cars rot in no time.

We rarely get snow in Portland, Oregon, and when we do, they don't use
salt (tree huggers).
