NCAP overall
2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
SCHOOL, TRANSIT, OR HEAVY DUTY VEHICLES EQUIPPED WITH SPICER 6,000 OR 8,000 LB. FRONT STEER AXLES. THE TIE ROD END CAN PULL OUTBOARD AND SEPARATE FROM THE TIE ROD TUBE DUE TO IMPROPER THREAD ENGAGEMENT BETWEEN THE MALE TIE ROD END AND THE FEMALE TUBE.
Consequence
SEPARATION OF THE TIE ROD END COULD RESULT IN LOSS OF STEERING CONTROL, INCREASING THE RISK OF A VEHICLE CRASH.
Remedy
DEALERS WILL REPLACE THE COMPLETE TIE ROD ASSEMBLY.
Defect
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH T444E DIESEL ENGINES. A FUEL LEAK CAN OCCUR BECAUSE OF OVERCRIMPING OF THE HOSE END FITTINGS ON THE HOSE FROM THE REGULATOR TO THE LEFT HEAD AND THE HOSE FROM THE FUEL TRANSFER PUMP TO THE REGULATOR.
Consequence
FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, CAN RESULT IN A FIRE.
Remedy
DEALERS WILL INSPECT THE OIL HOSE AND PLACE AN ADDITIONAL CONVOLUTED LOOM AROUND THE EXISTING OIL HOSE, OR REPLACE THE HOSE ASSEMBLY.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
Yes — NHTSA lists 2 recall campaigns affecting the 1998 Navistar 3600. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
