1999 HONDA CR-V Engine ground

Knuckle/Hub Replacement
Note these items during replacement:
. Replace the selt-locking nuts after removal.
. The vehicle should be on the ground before any bolts or nuts connected to rubber mounts or bushings are tightened.
. Torque the castle nuts to the lower torque specifications, then tighten them only far enough to align the slots with each
pin hole. Do not align the nuts by loosening.
o Use only genuine Honda wheel weights for aluminum wheels. Non'genuine wheel weights may corrode and damage
the aluminum wheels.
. Onthealuminum wheels, remove the center cap from the inside of the wheel after removing the wheel.
. Before installing the brake disc, clean the mating surfaces of the front hub and brake disc.
. Before installing the wheel. clean the mating surfaces ofthe brake disc and wheel.
. Wipe off the grease before tightening the nuts at the balljoints.

Troubleshooting
Symptom Ghart
For electrical malfunctions which are indicated by the self-diagnostic system, reter to selt-diagnosjs function (see next
page).
Note these items before troubleshooting a symptom.
. Check the engine coolant level, and allow the engine to warm up before troubleshooting.
. Anv abnormality must be corrected before continuing the test.
. Because of the precise measurements needed, use a digital multimeter with an output of 1 mA or less at the 20 kO
range when testing.
. Before performing any troubleshooting procedures check:
- Fuses No. 47 17.5 AJ, No. 55 (40 A), No. 56 (20 A), No. 57 (20 A) in the under-hood fuse/relay box, and No. 17 {7.5 A) in
the under-dash fuse/relay box.._ Grounds No. G101, G201, G202, G401, G4O2
- Cleanliness and tightness of all connectors
