Rear hatch struts failed.
Left rear central locking failed (servo).
All central locking failed (caused by shorting wires under dash).
Electric seats were beginning to have a bit of movement.
Gears did not change down properly (caused be incorrect adjustment of throttle cable).
I suspect the rear LSD has locked, resulting in tyre squeal when cornering and increased rear tyre wear.
I loved my Jeep, but fuel prices here in Northwest Australia meant it became too pricey (AUD1.45 per litre).
It was an amazing vehicle off-road and has out climbed Landcruisers in some of the toughest terrain.
The leather interior is actually better in hot, dusty climates, regardless of what most people think, as it stays cool and doesn't gather dust.
Parts in Australia are expensive: headlight AUD950, air-con controller AUD2000, front seats AUD7000 each!! and if the seats go, there is no way of adjusting them.
The 4.0L flat six is getting on and is thirsty, but has plenty of power, especially low down.
If you are looking at buying a Grand Cherokee LTD, ask yourself this:
"Could I afford to buy it new?"
...because if your answer is "no" then you may not be able to afford to replace parts in a second-hand one.
