1997 4.0 oil pump replacement?? Please help

[Datman]

Hi All,

I see plenty of later model oil pump replacement how to’s...but I cannot find anything for my 1997.
At start up sounds like squealing under the passenger floor board....
I belive my oil pump is shot. I’ve searched here and searched YouTube and could not find anything on how to replace the early TJ oil pump....

before the noise started my oil pressure gauge was jumping and then read way low.
I ran the gauge test and no codes thrown...I ruled out the oil pressure reading unit due to gauge working during test and the squealing at start up.

I put in heavyweight oil and presssure seems to be reading normal but still fluctuates some...

I’m hoping someone can direct me to a link on how to replace the oil pump in a 1997 4.0 TJ.

thanks guys!

I don't know of a '97 specific write-up but the '97 factory service manual is available at the bottom of this post: https://wranglertjforum.com/threads...-fsm-technical-documentation.4618/#post-62640
