I got a bit delayed doing the 30K service , as per Isuzu its minor and they only do the front hub greasing apart from the check ups.
I changed the oil, oil filter and fuel filter as well as i have a habit of doing this every 10k kms. Cleaned AC and Air filter, torqued suspension, cleaned the brake liners.
Also oiled the rear cover motor gears
Hub greasing and greased the upper arms, also grinding the upper arm cap slightly.
Hub oil seals
Old fuel filter, this was replacedthough isuzu has a 20k km interval
Cleaned the hub items with diesel, greased and put back
