No.
Will bolt up, but will not shift. The 1998 is controlled differently by the computer.
A 1998 Jeep Grand Cherokee has a four speed automatic transmission.
The only differences are between a regular Cherokee and a Grand Cherokee.
Me friend has a 1995 (same model as yours) jeep grand Cherokee with a 4in lift and it seems to be fine. I have a 1998 grand Cherokee and am thinking about putting some spacers in it.
Yes!
yes
NoNo
A Cherokee would have the AW4. A Grand Cherokee would have a 44RE.
It is not adjustable.
Check the belt tension. it is too hard on the bearing or it's running dry.
"how do you change a throttle position sensor on a 1998 jeep grand Cherokee?" could someone without any experience do it?
Since running boards were an option that replaces the rocker moulding I would say YES
