Stimmel1647545512 Posted December 17, 2012 Report Share Posted December 17, 2012 2001 WJ quadraTrac 74120 miles, 4.7 v8 had the car make a chatter comming from underneat the car, shop told me it sounded like a starter staying engaged and hitting the flywheel, the problem was only occasionally, went away for a few weeks came back, So i put a new started in the car, all was good for a few days and now its back!! No major problems with the car always fires right up when i did the starter there were no shims and the mopar unit came out, does this sound like a got a bad starter out of the box? does this sound like maybe loose flywheel bolts? anyone ever had a similar problem? I did the starter and it was fine for days, problem popped back up friday night didnt drive the car at all until today did it every time i drove it today! The noise seems to be non existent when in neutral or low rpm but leaving a stop its present, doesnt do it in reverse what so ever regardless the rpm and does not do it in neutral unless the rpm is on the 4k or high side, my next step would be to put it on a lift and have someone check the flywheel for cracks or loose bolts, that being said I tried to include as much info as possible.

Rocky31186 Posted December 17, 2012 Report Share Posted December 17, 2012 Got a video? The only cracked flex plates I found on Toyotas did it all the time. How did the teeth look on the starter you removed? Quote Link to comment Share on other sites More sharing options...

Rocky31186 Posted December 17, 2012 Report Share Posted December 17, 2012 I can't remember if that bell housing has a inspection plate? I would check to make sure the bolts are tight. Quote Link to comment Share on other sites More sharing options...

Rocky31186 Posted December 17, 2012 Report Share Posted December 17, 2012 If that's not it, I have heard the 4.7 makes this noise right before a piston lets go. Something to do with carbon build up lets go off the top of a piston, bounces around and scores the cylinder walls. Quote Link to comment Share on other sites More sharing options...

Tractor Posted December 17, 2012 Report Share Posted December 17, 2012 Check your front driveshaft, they go bad and do crazy things. Especially if its the CV type. Quote Link to comment Share on other sites More sharing options...

Tractor Posted December 18, 2012 Report Share Posted December 18, 2012 It's sitting still??? He is under the truck taking a video. Mine was making a horrible noise while sitting as well before I removed the front drive shaft. When I got under it, it was obvious though as the CV was jittering a lot.

Shawn89 Posted December 18, 2012 Report Share Posted December 18, 2012 Mine had a bad cat by the starter that made a weird rattle sound Quote Link to comment Share on other sites More sharing options...
Stimmel1647545512 Posted December 18, 2012 Author Report Share Posted December 18, 2012 had a reputable shop look at it all day, all bolts are tight and everyhting is in place, upon inspection of the flywheel something is making contact with it ever so slightly to make this god awful noise! next step new flywheel possible crack, either way trans has to come out!
