REAR AXLE · 1993–2002 · SWAP
Rear-Axle Swap: “Fits F-Body” Is Not Enough
The housing is only one piece. A successful swap has to satisfy every chassis, brake, sensor and driveline interface.
APPLICATION: 1993–2002 Firebird / Formula / Trans Am considering a 10-bolt replacement, 12-bolt, 9-inch or other aftermarket rear.
Brake interfaces
Caliper/backing-plate mounting, rotor offset, hydraulic hose routing and parking-brake actuation must match the chosen rear.
Electronic interfaces
ABS/TCS sensor and reluctor architecture must match the car. “ABS compatible” is not specific enough unless the channel arrangement is stated.
Driveline interfaces
Pinion/yoke, driveshaft length, U-joint, torque-arm mount and pinion-angle range must work together.
DO NOT ORDER FROM YEAR RANGE ALONE
Before purchase, document year, ABS/TCS option, current brakes, transmission, driveshaft, torque arm, wheel package and intended rear width.
FPV RULE
OBSERVE → MEASURE → ISOLATE → PROVE → REPAIR → VERIFY. Do not turn a symptom, DTC or catalog fitment label into a parts order.
