1985 ISUZU TROOPER Power Trainaxle Assembly Problems

1ST INCIDENT OCCURRED 1990 AT 5 MPH. LOST POWER. WHEEL WAS EXTENDING FROM CAR. 1200 MILES LATER, 2ND INCIDENT OCCURRED AT 40 MPH, NEAR CLIFF. WHEEL AND AXLE DEPARTED, PASSED VEHICLE, SWUNG BACK & HIT VEHICLE. PAID LAREDO TX DEALER TO DISMANTLED OTHER AXLES AND EXAMINED DIFFERENTIAL. 1200 MILES LATER REAR DIFFERENTIAL FAILED. CHARLSTON, SC DEALER GUARANTEED NO FAILURE. SEVERAL THOUSAND MILES LATER, NOISE & AXLE HOUSING OIL SPILL. REPAIRED IN NEW YORK CITY. SEVERAL THOUSAND MILES LATER, ANOTHER AXLE HOUSING OIL SPILL. IN 1991, NHTSA REPORTS THAT THEY HAVE NOT HEARD OF SIMILAR INCIDENTS & CAN'T HELP. SOLD VEHICLE AT LOSS WITH FULL DISCLOSURE & RECOMMENDATION TO REPLACE FULL AXLE HOUSING. 9 YEARS LATER, I HEAR OF A SIMILAR INCIDENT IN ANOTHER ISUZU TROOPER. NHTSA DATABASE (2000) REPORTS NO RECALL IN THIS AREA. IS THIS SERIOUS ENOUGH OF A SAFETY ISSUE FOR NHTSA TO EXAMINE?*AK
