My first impressions of the FI Spool is that it is no joke.
I have run the Axial iron cross lockers since day one. They have always had a bit of play in them and not a tight fit to the axle shaft tang. The FI Spools you will need to press the axle tang into the spool. If you do not want to press them in you can lightly sand the tang until you get a snug fit.
Both the cases were worn through.
Besides comp'n I enjoy trail rides and water crossings. I wanted to make sure that the axles were well greased, I used green marine grease the last time I put them together. As you can tell I went a bit overboard.
Here are the rear axle shafts after pulling them out of the cases.
On the bright side they are not rusty at all.
This time around I took it much lighter on the grease, I went with the blue VP grease.
Here is the FI spool mated up with my front overdrive gear with the bearings in place.
Greased up the pinion and meshed it with the ring and FI Spool.
Finished front axle
Finishing up the rear axle was a snap.
These have been in My Class 2 rig since July 5th 2013, I have had no issues at all.
See you on the rocks, JSLICK
