Thanks to this forum, I gained lot's of knowledge about my Jeep, to the point that I even started playing mechanic (which is - when you are official mechanical retard with two left hands - like myself - very dangerous)
Today I decided to change the engine oil and to change the rear differential fluid. Went to store and bought Mobile 1 (5W - 20) - 6 quarts, and Mobile 1 75W-90 differential fluid. Thanks to this forum, I already knew about the site where to order my Wix 57526 filters, so I had 3 filters delivered to my house few days ago (at dirt cheap price).
Engine oil change went smooth. The only problem is that I almost had a hard attack when I noticed that my oil drain plug was so lose I could unscrew it by my hand
. Yet another reason not to take my Jeep to oil change place and trust some 18 year old punk with my Jeep. I know for sure from now on I am doing my engine oil changes.
With rear differential I had a little problem.
I have 2013 JKU Rubicon and I just turned 4,500 ml on it.
I decided to dump the original differential fluid and go with synthetic. Prior to this I educated myself here as much as I could, plus I did some research on Internet on the fluid capacities of my (Rubicon's) differential which is Dana 44. I found out that it takes about 2.25 quarts (by many) or about 2 quarts (by some).
When I came from work I jumped on that task while engine and everything was hot. I opened both plugs of the differential and let it drain for solid 1 hour. When the fluid stopped dripping I closed the bottom plug and started pouring fresh fluid in. I came close to 2 quarts when I already reached the point where fluid is leaking out (from the upper) hole.
I forgot to say that I noticed when I took of first the upper plug that fluid started coming out like crazy. It appeared to me like dealer filled it up to the max (probably over filled it).
Now I have to go to bed thinking I don't have enough fluid in my rear differential - because I didn't even reach 2 quarts let alone 2.25.
Should I drive it around tomorrow and re-check this situation ?
