changed the oil. wix and a mix of mainly regular 10w30, and mobil synthetic 10w30. At work, if theres just a swig of oil left in a jug, we dump it all in one container, 1 for each weight, blend doesn't matter. Then we use it in our personal vehicles. Replaced rear diff fluid, added some additive to it. Filled up transmission also, as it was a good amount low. Did a good inspection, found i need the front end gone through, king pins, fulcrum kit, tie rods, idler, pitman. its pretty loose. Its all fixable though in the end with time and money :) also found rear trans seal is leaking a little bit. when i drained the oil, i noticed it seemed clean, like not at all dirty, like 500 miles clean. Looked at the oil filter, and someone wrote on it the date it was last changed. 7/09!! wow this last owner told me he had it for about 3 weeks and did not drive it much. i believe him now 96,502 on the odo today
