YES - go to 3.
NO -

Fill/bleed sytem

2. Is problem a leak?

YES - Diagnose.

See Power Steering Fluid

Leaks

NO -

continue

3. Is drive belt tension correct?

YES - go to 5.
NO -

retension.

See ENGINE, Repair, Drive

Belt

4. Is problem resolved?

YES - end
NO -

continue

5. Carry out pressure test at idle and 1000 rev/min.

See Power Steering System - Test

6. Is correct pressure achieved?

YES - steering box defective
Not at any speed go to 9.
Not at idle go to 7.

7. Is idle speed correct?

YES - Go to 8.
NO -

Correct idle speed -

If 3.9

See ENGINE TUNING DATA,

Information, Engine 3.9 - V8i

NO -

go to 9.

9. Bypass steering box using adaptor tap

LRT-57-001

10. Is correct pressure obtained?

YES - defective steering box
NO -

defective steering pump

CAUTION: Do not hold steering wheel on
full lock for more than 30 seconds in any
one minute to avoid overheating fluid and

possibly damaging seals.

NOTE: 1. Excessive pressure in the
system is almost always caused by a
faulty relief valve in the PAS pump.

NOTE: 2. Insufficient pressure in the
system is usually caused by low fluid level
or PAS pump drive belt slip, or one of the

following: PAS system leaks, faulty PAS pump
relief valve, fault in steering box valve and worm
assembly, leak at piston in steering box, worn
components in PAS pump or box.
