M5R1 Mainshaft Differences
What are the differences between different 4x4 mainshafts in the M5R1? WIll they work in any '03 4x2 transmission for the 3.0L?
I'm going to convert my 4x2 M5R1 to 4x4. In my search for a new mainshaft, I was told that the design changed in 2001. Upon further research, it seems that the 4x4 M5R1 behind the 3.0L came in two varieties: F87A-DA ('98-'04) and 1L54-DA ('01-'07).
The mainshafts have two differnt part numbers:
F87Z-7113-AA for the F87A-DA
1L5Z-7113-AA for the 1L54-DA
Any idea as to the differences? Compatability?

Anyone need to get rid of stock 4WD Spindles, CVs, Front Diff (4.10), Front Dive Shaft, T-Case, or 4x4 ABS Pump?
