Oil and filter change on the pussycat (Jag). 20 minutes. Then an hour to jack it up on all four corners (I should get a darn lift) to change differential oil. The British figured out how to make the task near impossible.
Remove spare tire, remove covering to rear firewall, pry off an inspection plate, find flexible 1/2" swivel 'cause the fill plug is 2" offset from said inspection plate, attach extender and 1/2" ratchet, cuss loudly and colorfully at the ancestries of all those motherf**** who designed this thing.
Get a jug of 90W fluid and a hand pump, to which attach 3' plastic hose to reach the fill hole of differential. Pump fluid. Since the fill hole now is not easly visible, pump, pull out hose look at level, pump, rinse repeat until fluid is now running out and down the frame into a the oil pan mercifully remembered to put under rear differential frame. Cuss some more. Crawl under lifted car try and maneuvere the fill plug through the now thoroughly well oiled frame and start a few threads. Cuss some more. Crawl out and climb into trunk. Maneuvre the swivel into the square hole of the plug, not an easy task as the swivel tends to flop down and avoid being inserted into the fill plug. Say several hail marys and our fathers in a s many languages as I can muster. Finally success, attach extender and ratchet, tighten plug. Recount more of the holy ancestry of all the British engineers. Wipe hands.
Lower car to terra firma.
Suck up two cans of Fosters in rapid succession. Answer yes Hon when wife announces DINNER. Wash hands, enjoy dinner. Repeat excercise in two years or so.
So how was your day?
Rewarded my bravery with a strawberry shake.
