Alignment on Volvo 850 — Specifications & Procedures

There is a small amount of adjustment at the bottom strut bolts. With those bolts in one can move the strut in or out slightly to get more or less camber. As the knuckle moves it changes the toe setting slightly, therefore an alignment is a good idea. On my cars I always set the camber as far neg. as it’ll go, it maybe ends up -.25 degrees or so., then I don’t have to worry about resetting the toe if I do upper strut mounts or a lower control arm. Besides, it corners better :-).

Prior to performing wheel alignment, perform preliminary visual and mechanical inspection of wheels, tires and suspension components.

Ride Height Adjustment

Before adjusting alignment, check riding height. Riding
height must be checked with vehicle on level floor and tires properly
inflated. Bounce vehicle several times and allow suspension to settle.

Visually inspect vehicle for signs of abnormal height from
front to rear or side to side. Check passenger and luggage
compartments for extra heavy items and remove if present. Riding
height between left and right side of vehicle should vary less than 1″
(25.4 mm).

Jacking & Hoisting

The following illustration indicates areas (parts) of
underbody and frame used to raise and support vehicle with either
floor jack or hoist. These points are indicated by shaded areas on
frame.

Wheel Alignment Procedure

CAMBER ADJUSTMENT — Front

1) Raise and support front of vehicle. Camber angle can only
be adjusted by altering the spring struts. Disconnect spring strut.
Drill out upper holes in shock absorber attachment to 14 mm. Ensure
holes are cleaned of burrs after drilling.

2) Install Washer (3 546 451-0) using one old bolt and nut in
lower hole. Do not tighten nut. Install Fixing Plug (3 546 450-2) in
upper hole. Drill a 4 mm hole through center of washer and shock
absorber attachment. Pound Clamping Pin (951 950-5) into 4 mm hole.
Remove centering plug and bolt.

3) Install Eccentric Bolt (3 546449-4) in upper shock
absorber hole and new Bolt (977 267-4) in lower hole. Slightly tighten
new nuts. Adjust camber angle, as necessary, by turning upper bolt.
After adjusting, tighten both nuts to 48 ft. lbs. (65 N.m), then
tighten an additional 90 degrees.

Camber angle cannot be adjusted unless car is raised.

CAMBER ADJUSTMENT — Rear

If camber angle is not to specification, check for trailing
arm damage.

CASTER ADJUSTMENT

Check caster angle on both sides of vehicle. Caster angle can
vary by one degree maximum between right and left sides.

TOE-IN ADJUSTMENT — Front

To adjust toe-in, lengthen or shorten tie-rod ends as
necessary. Loosen lock nuts and adjust tie rods. Longer rods will
result in a larger angle and shorter rods will result in a smaller
angle. Maximum possible variation in length between tie rods is 2 mm.
Take measurement between edge of thread and lock nut. After
tightening, apply rust proofing to tie rod threads.

Tip: Count the tie rod revolutions

TOE-IN ADJUSTMENT — Rear

1) To adjust toe-in, loosen nuts connecting transverse arms to trailing arms. Move transverse arms forward or rearward until correct value is obtained. Tighten one nut on each transverse arm anchor to lock it in relation to other trailing arm.

2) Replace other bolts and nuts that are not tightened with
new bolts or nuts. Tighten nuts to 37 ft. lbs. (50 N.m), then tighten
an additional 150 degrees. Replace 2 previously tightened bolts and
nuts. Tighten to specification.
