OK so I didn't do it all in one day but, in this last week:
*Changed transfer case fluids
*Replaced right-rear wheel bearings (omg hate that design)
*Painted diff covers and changed both fluids
*Installed drain plug in rear diff
*Sandblasted and painted air box clips (were rusty)
*Cleaned up and re-mounted my full-spare (also very corroded and wasn't sealing
*Replaced the front-to-rear metal brake line, was almost rusted through, one bend and it broke clean so.. it was toast - good catch on my part.
*Flushed all 4 corners brake lines.
*Changed wiper blades to some nice quiet silicon Bosch ones.
*Finally snagged a OE (Mopar) hitch assembly and a decent install kit from U-Pull it - only had to wait 2 weeks for them to get on that still had it. $25! That made my week haha.
My Jeep already has all the other "tow package" stuff on it.. but didn't have a hitch... don't ask me how that happened.
*Changed fuel filter, finally completing all scheduled maintenance on the Jeep after buying 2 weeks ago. PO didn't have records of anything really.. even though I could tell some had been done - couldnt say when.
Only things left to do now are exhaust which I am going to get very creative and do some re-engineering and tires (2), maybe
