HELP PLEASE!!!! 00 xj noises
Hello everyone, I have a 2000 xj limited with the 4.0 in it. 151,000 miles on it. It makes a weird noise only if you get on it kinda hard between 1200 and 2500 rpms. It sounds like something is loose but I cant find anything loose anywhere. It almost sounds like its coming from the front of the motor. If im being really gentle with it then it doesnt make the noise at all that I can hear of. I know the fan is not hitting anything. There is no fan shroud on it. Long story short it broke and I havent picked up a new one yet. The motor mounts are fine too if that helps. Also, there is one other noise that comes up every now and again that sounds like a heat shield is rattling around on the drivers side lower half of the motor only if I am sitting still and go to back up or pull forward a little bit and barely give it any throttle at all. But again, cant find anything loose. No idea whats going on here. ANY input would be greatly appreciated. Thanks in advance
Re: HELP PLEASE!!!! 00 xj noises
It sounds like it could be your flex plate. What kind of noise? Is it metallic? Clink, clunk, thump, rattle?

Re: HELP PLEASE!!!! 00 xj noises
Both noises are rattles. No clinks or bangs or clumps thumps or nothing thank goodness. On a very right budget lol
Re: HELP PLEASE!!!! 00 xj noises
for the front engine noise have you taken your belt off and checked all your pulleys, sometimes the idler pulley can go out or the water pump pulley and you wouldn't know until they are about ready to come off. also check the harmonic balancer i had to replace my boyfriends cuz we noticed a slight rattle when steppn on the gas hard and when we got together and he stepped on the gas when in park of course; i looked in the engine bay and noticed a really good wobble to it and when we took it off sure enough the bearing was about to explode*Rut RO*. but thank goodness for a good eye and second opinion we save are jeep from disaster.
Re: HELP PLEASE!!!! 00 xj noises
Never thought about the pulleys. I'll have to check them next time I have a day off. Really hope it's something that simple.
Re: HELP PLEASE!!!! 00 xj noises
Had same issue Brandon, and same solution, come up on a friend's 96 XJ; would rattle under acceleration and had a belt that was "walking" on the fan drive pulley. Replaced the HB, all's good now. Fairly easy to see; the balancing weight (outer ring) should be parallel with the hub (center piece) when looking at it from above. We got a new one for $45 at local auto parts store!
Re: HELP PLEASE!!!! 00 xj noises
Haven't checked anything yet but basically it's either play in the pulleys or the job or flex plate? I believe I'll start with taking the belt off and checking the pulleys first. I have replaced pulleys before but on a ford 390. Not too bad I don't think on the 4.0. How much of a pain is it to change the harmonic balancer and flex plate?
Re: HELP PLEASE!!!! 00 xj noises
HB is not bad. Might need.to pull the radiator though. Gonna have to pull the tranny to change the flex plate

Ah ok. Thanks everyone for the info! Just need a day off or to get off early. Not a good time to take off of work being a tree guy in md. Too much going on
Re: HELP PLEASE!!!! 00 xj noises
when or if you need to pull off the HB you wont need to pull the radiator i don't think at least i didn't have to when i did mine. you can rent a tool at the auto parts store that will help you get it off its a bit tedious but well worth the bleedn knuckles. if you have trouble i could make a vid for you on how to do it.
Re: HELP PLEASE!!!! 00 xj noises
That would be awesome. I'll see if I can pull the belt and check the pulleys tomorrow after work and go from there. Thank you

Re: HELP PLEASE!!!! 00 xj noises
give ya exhaust a good shake ...cat or muffler can rust up inside and make a rattle ..
Re: HELP PLEASE!!!! 00 xj noises
Already did that cantab27. That was my first thought. Exhaust is fine. Thanks for the tip though. All the pulleys seem fine as well.
