I pretty much agree with inkpot;
... The biggest thing on my radar is low oil pressure readings on the gauge, particularly at idle while warmed up. My immediate goal is to have a normal operating stock LC.
In hot weather, with the USA recommended oil, very low pressure is common, normal. Likely not an issue, but I prefer to use the “for everybody else but USA” Toyota recommended oil chart to select my oil. I go by the coldest temp that it will be started at, on the oil change. I run Mobil One 15W50, others have good results from 5 or 10W40. If the oil is fresh, wouldn't worry about it, when time to change, would step up in viscosity.
AU viscosity chart
1FZFE motor
20w50 oil- -7 deg to 38 plus ; 19 f to 100 f plus
15w40 oil -10 deg to 38 plus; 14 f to 100 f plus
10w30 oil -18 to +38 deg; 0 f to 100 f
5w30 -30 to 8 deg celcius; -22 f to 46 f
...The dealer said:
Front Cover and Rear Main Seals are leaking: $3200
Some what common, the "need" for a fix depends on the leak and your tolerance of leaks.
Front Sway bar is broken: $650
Depends on "broken". The mounts tend to break, most times, easy/cheap fix.
Steering Stabilizer needs replaced: $350
I'm

on this one. I ran the stock unit with a lift and big tires, it was

. Finally died, removed, ran with out and it was

. Bought an aftermarket (OME) heavy duty and it is

.
... Not sure they looked at steering knuckles, birfields, flux capacitors and other parts unique to offroad vehicles. ...
This is an important part, if some of this stuff is run low, short on lube, it can run into $$$$ in a hurry.
