hello all! need to r&r the harmonic balancer on my 99 4.0l soon....noticed a wobble at idle and it appears to be starting to separate, not surprising for 243k. done my researcing here and think i've got some good ideas for getting the job done. my plan is to just go ahead and pull the timing chain cover and take look at the timing set. anyone with tips and advice for what i might run into, i'd sure appreciate your feedback. sourced an ATP HB, and felpro TC gasket set, have the puller and 5/8-18 3" bolts, 1/2-20 5" bolt for installing the pulley. the bolt holding the original pulley spins off no problem :yelclap:. want to do it myself, and do it right....guess my question really is deciding whether or not the timing set needs to be replaced once i get to it. the jeep is a stock DD.
