Damn Nice. I got bored at work and made an excel spreadsheet for all my service. Plus folders with invoices and receipts uploaded and locked year/quarter/month

Service is done... did the rear diff this morning, pulled the cover and was shocked at how clean it all came out. Going to leave the front diff and put it on a 100k interval since I have the lockouts and it does not get the full use out of it.

once upon a time i had beeen doing the front bearings once a year (35k/yr), then once every 2 years, this time around it was 3. had no play or alarming noises and was running fine. used a shop the last few times since i was in an apt, this time with a garage over my head now it was up to me so it got done a few weeks back. had an issue with one sides brake carrier bolts that slowed me down but some deep creep penetrant broke the bond and bolts came off easy on the other side. which suprised me cause apparently surface rust was starting to grab the bolt shoulders and lock it in there. sprayed the shoulder with fluid film for next time.
total time on side 2 was quick, maybe 45 min to wheel back on ground. used royal purple grease as it was on hand and no reason to use anything else. repacked the outer and did the same on inner without removing the seal, left the inner bearing in place, packed... rotated bearing and repeat until satisfied. the inner bearing i used to pack but at the advice of spyntec (iirc) and the condition of it the last time i looked at it, i stopped. since the axle does not move all that often it can be pushed out a ways. the last time i looked at it was when i pulled the thuren kit for a repair, 2015 or so. probably should take another look at it. have axle ujoints to do and will have a look then.
going to do it every 50k moving forward...

Thanks Steve, that sounds reasonable. I redid mine the first time at about 30K miles/50K Km’s because the front end got wet for a couple of hours when it sat in water after a failed attempt to get a boat and trailer out of the water on a rolly pebble beach. Had to change a couple of bearings because of discolouration. The 50K miles looks good for me as my truck is a 95% pavement queen and not doing any boat launch or loading duties any more. Good info.

Purple must be your favorite color Steve lol.
I just read this post and feel I am way behind in some of my maintenance.
This will motivate me to change some fluids like my rear diff and front diff.
I have my transmission serviced every year and just did a brake flush when I replace my front and rear rotors and calipers along with shoes.
I took my old calipers off and rebuilt them as it was not that hard so why not.
Have a great Thanksgiving.

Yes, purple everything lol... I like that I dont have to think about maintenance... every 10k on the 10k, 25k on the 25k etc... It allows me to plan ahead for all of it so much of it can be done in one shot.
Yes RP in the tubes. I also recently had my axle u-joints swapped by a shop and requested they put a dab of grease on the inner bearing for the stub shaft (the one in the hub). That is whatever grease they have.
