Removal
Drain the transmission oil or fluid {see section 13 or
14t.
Remove the left driveshaft (see page 16-3).
Bemove the three dowel bolts.
Remove the intermediate sh8ft from the differential.
CAUTION: Hold the intermediate shaft horizontal
until it is clear ot th6 difforantirl to prevont damage
to thc ditf€rential oil seal.
7. Install the knuckle on the lower arm.
NOTE: Wipe off the grease before tightening the
nut at the ball joint.
CAUTION:
. Be careful not to damago the ballioint boot.
. Torque the castle nut to tho low€r torque speci-
tication, then tighten it only lar onough to align
th6 slot whh tho pin hols. Do not align the nut
by loosening.

The Integra SRS includes a driver's airbag located in the steering wheel hub and a passenger's airbag located inthe dashboard above the glove box,
Information necessary to safely service the SRS is included in this Service Manual. ltems marked with an asterisk(*) on the contents page include, or are located near, SRS components. Servicing, dissssembling or replacing
these items will require special pr6cautions and tools, and should therefore be done by an authorized Acura dealer.
. To avoid rondoring ths SRS inoparstivo. which could |rad to parsonal iniury or doath in the ov€nt of ! sev6.o
trontal collision, all SRS sarvice work must be perto.med by an authorizod Acura dsalor.. lmpropor 3orvic€ procadures, including inco[6ql rgmoval and inrtallation of the SRS, could l6ad to pgrsonal
iniury clus€d by unintentional doployment of the airbags,. Do nol bump tho SRS unh, (Xherwise, th6 3ystom may fail in cas€ ol a collision, or the airbags may d€ploy

NOTE: The original radio has a coded theft protection circuit. Be sure to get the customer's code number before- disconn€cting the battery.- removing the No. 47 (7.5 A) fuse from the under-hood fuse/relay box,- removing the radio.
After service, reconnect power to the radio and turn it on. When the word "CODE" is displayed. enter the cus-
tomer's 5-digit code to restore radio operation.

INPUT SHAFT
High assist at lower speedsl
When steering resistance is high, such as when driving at low speed, or when turning the wheel with the car stopped, the
diiference in angle created between the input shaft and the valve opens the tluid passage on one side, and closes the fluidpassage on the other side, at each pair of orifices. The fluid pressure lncreases in the side of the power cylinder fed by thelarger fluid passage. This increased pressure pushes on the rack piston, allowing the steering wheel to be turned with light
effon. On the other side of the power cylinder, the return passage opens allowing the steering fluid to return through theinput shaft to the reservoir. The fluid passages to the power cylinder automatically change in size, increasing as the steer-ing resistance increases. In other words, the passages become larger and power assist increases when the steering effort
would normally be high, (for example, when parking or making low speed turns), and the passages become smaller andpower assist decreases when the steering effort would normally be low, (for example, when driving at high speeds or
straight ahead).

Pressure Control
Low assist at higher speedsl
When steering resistance is low, such as when driving at high speeds, or when driving straight ahead. the lnput shaft is
near or in the neutral position, so there is liftle or no flow to any of the power cylinder orifices. Most of the feed pressure
from the pump is bypassed to the reservoir. Because of this, the pressure stays the same in both sides of the power cvlin-
der, resulting in low or no assist.

. ls the power steering pump belt properly adiusted?
. ls steering fluid reservoirtilled to proper level?
. ls the engine idle speed correct and steadyT
