Be sure there is RED locktight on those 6 bolts. A couple of people have had them back out......including me. Red locktight is a diesel swapers friend.
Coming from a business doing electric vehicles conversions for 27 years I just never have to worry about vibration so the diesel swaps have been a real introduction to the problems of the ICE.

Good to know. I have red on the crank spacer bolts and flywheel bolts. I was always kinda used blue or green locktight on aluminum as the softer stuff would sometimes take the threads out with red. These went in dry. They will get something going back in this time though.

So finally got the truck back together. Replaced all the ball joints and bushings, shocks, steering rack and pulled my 240K mile trans and put in a 150K mile spare NV3500. Also lock tight on every adapter bolt. Had one that was loose making me think it was a transmission noise as it was rubbing the back of the flywheel and all others were snug but not as tight as when I put them in. Lock tight should fix all that now.



The big upgrade though was the 40lbs (more like 42) flywheel. stock4.0 jeep is 27lbs




The rattling intermediate shaft in the NV3500 is definitely quieter. The from idle inertia helps too not that it was lacking before. But now its smooth no matter what gear or throttle input your giving. Its a must buy IMHO.

Tires and alignment is next.

Wheels tires and alignment. I went with a deal I found on a 265/70 r17 Goodyear Authority used. Measures 31.7 inches. Anything bigger than that would rub for sure.




I need to do a boost leak test as today I got overboost code. Kinda worried me at first as it wasent making much part throttle boost suddenly on the highway and egts went up. It cleared up after a restart. Ill have to do some research on causes for that.

Are you attributing the quiet NV3500 idler rattle (marbles in a can sound) to the flywheel or is it a result of the different trans?

Is the surface on the centerforce FW curved as the oem one is supposedly?

Which clutch are you using...or how much is it rated for?

Flywheel for sure made the difference. My original trans is still good and measured the same lash as the newer one.

Not sure on the curve? looked like stock except the back is completely solid.

Clutch is a stock $46 rock auto clutch for a 2001 4.0 jeep.

So this week I am working on getting cruise to work. First I wired up a 5pin 40amp relay to act as my TDi brake switch. Nice to finally have that 1400rpm throttle cut out after startup finally fixed. Next I attempted to grab the Dodge VSS signal coming off the ring gear and feed pin 20/121. But VCDS said no signal. This didnt make sense to me as Reddoks Jeep swap worked this way.



See here is the VSS diagram. Looking at it now I tapped into the-Neg side. Maybe it needs to be on the+ side?

Well tapped the positive side and still nothing . I might have to get a dakota digital box and vampire the speed signal coming out of the ABS unit white/orange wire. Still would like to know why its not working though.
