wheel CADILLAC ELDORADO 1993 10.G Workshop Manual

Downloaded from www.Manualslib.com manuals search engine While the tires available as standard or optional equipment on General
Motors vehicles may vary
with respect to these grades, all such tires meet
General Motors performance standards and have been approved for use
on General Motors vehicles. All passenger type
(P Metric) tires must
conform to Federal safety requirements in addition
to these grades.
meel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give
you the longest tire life and best overall performance.
In most cases, you will not need to have your wheels aligned again.
However,
if you notice unusual tire wear or your vehicle pulling one way
or the other,
the alignment may need to be reset. If you notice your
vehicle vibrating
when driving on a smooth road, your wheels may need
to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted. If wheel nuts
keep coming loose, the wheel, wheel bolts, and wheel nuts should be
replaced. If the
wheel leaks air out, replace it (except some aluminum
wheels, which can sometimes be repaired). See your Cadillac dealer if any
of these conditions exist.
Your dealer
will know the kind of wheel you need.
Each new
wheel should have the same load carrying capacity, diameter,
width, offset, and be mounted the same way as the one
it replaces.
If you need to replace any of your wheels, wheel bolts, or wheel nuts,
replace them only
with new GM original equipment parts. This way, you
will be sure to have the right wheel, wheel bolts, and wheel nuts for your
Cadillac model.

Using the wrong replacement wheels, wheel bolts, or wheel nuts
on your vehicle can be dangerous. It could affect the braking
and handling of your vehicle, make your tires lose air and make
you lose control. You could have a collision in which you or
others could be injured. Always use the correct wheel, wheel
bolts, and wheel nuts for replacement.

A CAUTION
Putting a used wheel on your vehicle is dangerous. You can’t
know how it’s been used
or how many miles it’s been driven. It I
could fail suddenIy and cause an accident. If you haw ~ II replace
a wheel use anew GM original equipment wheel. I

Occasional waxing or mild polishing of your Cadillac may be necessary to
remove residue from the paint finish. You can get
GM approved cleaning
products from your dealer. (See “Appearance Care and Materia\
ls” in the Index.)
Your Cadillac has a “basecoatlclearcoat” paint finish. The clearcoat gives
more depth and gloss to the colored basecoat.

ALUMINUM WmELS
Don’t use chrome polish on your aluminum wheels. Use wax after you
clean them. Also, don’t use abrasive cleaners or cleaning brushes on them
-- you could damage the protective coating.
WEATHERSTRIPS
‘These are places where glass or metal meets rubber. Silicone grease there
will make them last longer, seal better, and not squeak. Apply silicone
grease with a clean cloth at least every six months.

Downloaded from www.Manualslib.com manuals search engine This transaxle is the first of a new generation of “SMART” transmissions.
The computer which controls the electronic shift solenoids adapts to
changing environments while you drive. This provides consistent high
quality shifts under all conditions. Communication between the engine
and transaxle through this computer controls engine output durin\
g
activation
of torque management or traction control. Smooth shifting is
ensured by design. Hydraulic accumulators control shift pressures and all
shifts are made to free wheeling elements.
The 4T80E uses a dry sump lubrication system with a scavenger pump.
This unique feature enables the transaxle to maintain adequate
pressurized oil supply during
all maneuvers.
Spirited performance with
very efficient cruising operation are provided
by the combination
of 4 speed overdrive gearing, a torque converter
clutch, and a
3.71:l or 3.11:l final drive ratio.

Your fully independent front suspension is a combination strut and spring
design.
The frame is isolated from the body with six rubber mounts.
Rubber bushings are used at
the lower control arm pivots. Thc upper end
of the strut is isolated by a rubber mount which contains a bearing to
allow
for wheel turning. The Road Sensing Suspension on the 4.6 Liter
(Northstar) and the Speed Sensing Suspension on
4.9 Liter will
automatically controls the damping rate of the struts.
The lower end of the steering knuckle pivots on a ball joint riveted to the
control arm. The ball joint is connected to the steering knuckle
with a
castellated
nut and cotter pin.

I'
Your vehicle uses an independent short/long arm rear suspension. All the
rear suspension components are mounted
on a suspension support which
is attached
to the body at four points and is fully isolated with bushings
and insulators to minimize road noise. Each rear wheel
is connected to
the suspension support through the suspension knuckle using an upper
and lower control arm and toe
link.
The control arms and toe link are attached to the suspension support on
the inboard side, and to a suspension knuckle on the outboard side. The
hub and bearing assembly is mounted
to the knuckle and is a single, non-
serviceable unit which eliminates the need for wheel bearing adjustment.
The load leveling
(ELC) shock absorbers are attached to the lower
control arm, with the upper end
of the shock attached to the suspension
support.
The springs are held in position between the lower control arms
and
a pocket in the suspension support.
The suspension system also incorporates
a new damping system now as

Downloaded from www.Manualslib.com manuals search engine Sensing suspension on the Eldorado. These systems control the damping
forces in the shock absorbers and struts, in response to various road and
driving conditions. The systems are capable
of making these damping
changes extremely fast.
A computer receives inputs from vertical acceleration sensors, wheel to
body position sensors, vehicle speed sensor, lift and dive signals. This
computer evaluates the inputs from these sensors, to control the damping\

of each of the struts and shocks independently to provide varied levels of
suspension control.
The system also has the capability
of providing Speed Sensitive Steering
control.
This system changes your steering effort based on your vehicle
speed.
Speed Sensitive Steering
This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at
a lower speed for increased
maneuverability and parking ease.
As your vehicle speed increases, the
steering effort is also increased to provide a manual like steering feel for
maximum control and enhanced vehicle stability.

The power rack and pinion steering system,has a rotary spool valve which
directs hydraulic fluid coming from the power steering pump
to one side
or the other side
of the rack piston. The integral rack piston is attached to
the rack. The rack piston converts hydraulic pressure
to a linear force
which moves the rack left or right. The force
is then transmitted through
the inner and outer tie rods to the steering knuckles, which turn the
wheels
If hydraulic assist is not available, manual control is maintained. However
under these conditions more steering effort
is required.
