hey i got a 91 cherokee and maybe im just trippin and shouldnt worry but... after i got my new exhaust put on i noticed a little knock and a bad oil leak coming from my rear main seal . well the knock is kinda quiet and goes away when i give it gas, should i even be concerned about it? and how hard is it to replace the rear main seal?the 3rd video you can hear the knock pretty good and the first video you hear the little clank when my jeep starts. ouch. thanks

 

Check your fly wheel bolts. I had a 99 cherokee country that was making a knocking sound like that. It would go away when i would gas it or just be driving around but then it would come back when I stopped. My problem ended up being the that the fly wheel bolts were loose. Good luck.

 

I had the exact same noise but louder!!
Remove dustplate/inspection cover and tighten all four flywheel
bolts like he said!! Jeeps are notorious for that ..I put locktite
on mine

 

alright im going to give that a try on my next days off! thanks guys i hope that solves my little knocking noise

 

subscribed, possibly have same prolem

 

or the Flexplate cracked. Replaced mine twice allready. if thats the case while your at it check the rear main while it's off. ifs thats not leaking then valve cover it probably is.
