Does anyone know if the windscreen in a Toyota Landcruiser is bonded or not?

What do you mean by "bonded?"

The windscreen is a glass and plastic laminate and is held in place with a
urethane adhesive.

Depends on the year - I think everything past 1990 is. I know the
old FJ-40, FJ-50, FJ-60 and FJ-62 series cars are gasket mounted.

Depends on which model and age of Land Cruiser.

Just had my '98 100 series windscreen replaced and it is held by adhesive.
If you have no prominent rubber surround to the edge of the glass, yours is
also bonded.

Since the Toyota service helpline states that "the windscreen is an integral
part of the vehicle structure and provides strength and rigidity to the
body." Therefore a newly installed windscreen in a series 80 1991/1992
Landcruiser, which has NOT used the recommended adhesive or bond of any sort
has compromised the structure and strength of the vehicle.

Can anyone confirm that this is not the correct procedure for fitting a new
windscreen in this model. Also should it be possible to push the windscreen
out of its seating area about half an inch or so clear of the surrounding
bodywork it should be flush to, thus letting in moisture to rust the
paintwork.

The service helpline probably refers to current models. It is a long time
since I owned an 80 series but I seem to remember through the for of time
that it had an old-fashioned windscreen held be a rubber surround. This type
of screen is not held in place by adhesive. As to you pushing the screen out
letting moisture in, there is an answer; don't push it out;-)

The service helpline refers to all models, and they state it must be bonded.

Surely a vehicle of this type shouldn't have a loosely fitting windscreen?

Not according to every service manual about. They all state that a bonding
adhesive is to be used in replacement windows, this it true of another
Landcruiser series 80 owned by a friend, the windscreen is tightly bonded
in, unlike mine you cannot push the windscreen clear of the surrounding
frame with ease. The loosely fitted windscreen and the soft rubber surround
is causing moisture to seep into the cavities and stay thus rusting the
screen surround, incidently this was happening before I noticed how easily
the screen could be moved with minimal force.

Surely an off road capable vehicle of this type it would be essential to
have a proper fitted windscreen which is waterproof and rigid to the
vehicles body, or as other people have said "it could pop out if taking it
offroad."

I have had very many off-road vehicles and adhesive bonding has only been
commonly used since the mid 90's.
All my Range Rover classics, early Discovery, Shogun/Pajero, Land Rovers etc
had rubber gasket mounted screens. Adhesive mounted screens were used in
Isuzu Trooper from 93 on and later versions of all the above models apart
from the LR Defender which continues with a rubber mount.
If you should have a bonded screen, you will NOT have a full rubber surround
but you may have hard plastic trim fitted to close the gaps between certain
areas of the glass and body, especially at the top where it meets the roof.
If you have a screen that should be bonded but has not been, it would simply
not stay in place and would rattle and fall about because it does not have a
close fitting rubber gasket/surround fixing.
An adhesive fixed screen needs a rigid body which is further strengthened by
the screen itself. Earlier 4x4 bodies were far more flexible with chassis
that twisted in work. These needed flexibly mounted screens to allow
movement without stressing the glass.

"If you have a screen that should be bonded but has not been, it would

Does this include having a rubber which retains water underneth its lip
causing a severe rust problem since its fitting? And should the rubber leak
causing wet carpets?, and should the windscreen be able to physically push
out up to half an inch clear of the surrounding bodywork with minimal
fingertip force.

Usually no but I think water does get behind these rubbers by design. It
certainly gets behind bonded screens by design. Remember that your car is
around 15 years old and will not last forever without treating developing
rust.

The reason for the rust is that the company who removed and reinstalled the
new windscreen caused a cut line into the metal on removal, this was not
treated and subsequently has caused severe rusting over a year or so. There
is no way that a normal amount of water could penetrate a normally tough
paint job. I have compared this prevailing rust to other Landcruisers and as
expected the others do not have any rust in these location and the
windscreen is bonded tightly into place.

Thankyou for your time.

The only place to actually compare like vehicles is out in the physical
world unless you use photos. Usenet is limited in this regard.

I know a few photos would probably get my point acrosss more strongly.
