5L V8 Naturally Aspirated E7TE (225hp).
Quick reference
Verify installation specificities due to potential mid-cycle changes.
Consider checking for JDM vs USDM compatibility differences.
Context
When replacing the rear left CV axle on a 1987 Ford Mustang with a 5L V8 engine, look for OEM part numbers like E7ZZ-3B437-B and F1ZZ-3B437-A. These axles typically fit 1986-1993 Mustang models equipped with the 5.0L V8. Inspect the CV boot for cracks or leaks, as these are common failure points that can lead to axle damage. Installation requires lifting the vehicle securely and possibly removing the wheel hub assembly for access. Ensure all connections are tight and check for any unusual noises post-installation, which may indicate alignment issues. Be aware of the potential for mounting bracket variations between different Mustang models, so verify compatibility before purchasing used parts from junkyards.
