Took down the DS front axle this afternoon. Got it cleaned up a bit this evening and noticed some wear. I measured preload before I disassembled and it was 4-5lbs per fish scale.
The last time I did the front axle was 60k/14yrs ago. I reused spindle then, but dont remember if the wear was there or not. It was a marathon 16hrs project in a another mudder's driveway, so we werent being too picky. TIghtened preload once post-axle service, then drove for many years. Has driven fine. Doing front axle as PM, so no symptoms I am aware of.
Spindle [outer bearing wear spot has a slight edge that you can just grab with a razor blade. Inner bearing wear spot is visible, but no edge. Can wait for new spindles if need to be replaced.]
Outer bearing [doesnt look good to me, but I dont know how bad. Replacing bearings/races anyway.]
Inner bearing [this one looks fine to me, but not sure if those diagonal lies are manufacturing marks or not]
And finally hub outer bearing race seat [looks burned, but again I dont have an idea of how bad. Same as spindle, can wait for new hubs if needed] PS- FIPG was there before me. Prior owner smashed the flange edge trying to get it off, created a burr so the flange wouldnt seat and solved it with FIPG. It has been filed smooth and FIPG remnants removed. I didnt catch it the first time since we were racing the clock.
AND BONUS QUESTION - distal edge of axle splines that seat in birf look kinda funky but I wasnt really planning to do anything about it. Figured maybe from slamming it home?
Thank you for making it this far. Appreciate your thoughts.
