ZF5 Rebuild (Part 2) | Mainshaft Disassembly + Inspection | 7.3 IDI F-350

ZF5 S5-42 Rebuild Series:
Part 1: Full teardown https://youtu.be/Bb1yOZtmZnc?si=j-5_Qfg0-2TDc351
Part 2 (this video): Mainshaft disassembly + inspection

Today we continue the ZF5 S5-42 rebuild with a full mainshaft tear-down, cleaning, and inspection. This transmission came out of a 1990 Ford F-350 dually with the 7.3L IDI (RWD).

If you’re chasing hard shifts, gear noise, or planning a rebuild, this shows the wear points to check (synchros, bearings, gears) and what we’re replacing.
