Comon, you can do better. Lets see that paint pattern. You didnt show how you determened the pinion shim size too. You can make up for all the missing stuff on your front axle build...
hi, I did the same swap on my 2002 tj, with a 1999 engine. I kept my 2.5 harness frame but currently I have an ignition problem, what are the exact modifications you did you do on the harness please?
if you want true sound reduction you need mass loaded vinyl. This type of material will help with resonance from vibrating metal panels but if you want to go all out you need mass and a de coupling layer of closed cell foam. ResoNIx makes a really great product for this called ResoNix Barrier but its $$$. Good luck everyone trying to quiet down thier jeep.
Not sure how far along you are in the process, but there's quite a few things you would need to change i.e. Motor mount location, transmission, transfer case (or spline swap).
Nice work 👍🏼… I was thinking of doing the same to my YJ, & looking at either the killmat or dynamat products. I’ve also considered going over the sound mats inside my Jeep’s tub with bedliner. What do you think? Reduce sound (and possibly heat), while also keeping the tub protected from any water that might get in..
What about the driveshaft was causing the wobble? I feel like I'm experiencing the same thing based on the location and type of vibration - also only at highway speed. I assume the root cause were the u-joints? Thanks for posting this, I've been meaning to take a similar video to try to find my issue.
Did you change ECU from your 2.5 to an ECU for a 4.0? did you use your 2.5 wiring harness? where can i get a copy of the wiring change that in your video. i am in the process of removing 2.5 and installing MORE motor mount kit i purchased. just need help on figuring out the wiring. thanks james
Apologies for the late reply. Need to figure out how to get notifications on this thing. Let me know if you still need info. To answer your questions: 1.) I got my 2.5 ECU reprogrammed from this company called ARES technologies in Reiverside, CA. 2.) I actually ended up using a wiring harness from a 99 but required some mods to connectors. More trouble than it's worth, but it was the only wiring harness I could find for the inline 6. Good luck, if you haven't already finished the swap.
Nope. This is the new Oliver's drive shaft, but due to my ring & pinion gear ratio (left over from 4cyl days) the shaft is spinning way faster than what the vendor balances to, hence the vibes. I need to regear to proper gear ratio.
That was me in the white Gelandewagen. Made it up to Redbox road before turning around. There was a family in a new S-Class stuck at the large turnout before Redbox.
Awesome video! Am planning to do this with my yj, I planned on using a 200 mil silhess layer and then a closed cell foam on top of that. Was thinking about doing under the hood and the hard top too. Do you feel like the mats affected how the carpet fit in your tj?
I was never a fan of the Wrangler carpets. Always felt flimsy and never stayed in place. With the sound deadener or maybe anything underneath seems to keep the carpets in place better. Or maybe it's just too soon to tell?
It's been LA "cold" lately so can't speak for those summer drives, but I haven't noticed the usual amount of heat coming up... the foil back linging should help.
Hey there. Yea, I think it was worth it. I went into it with the not expecting much and knowing it's not going to get super quiet like a luxury sedan, but there is a noticeable difference from before. I was running no carpets and just herculined interior so I probably had the worst case scenario as a baseline. The best way I can describe the change is that all the noise is now muffled. My only regret was not accurately taking decibel readings before. I plan on installing kilmat in the door panels as well to if I can get it even quieter, ha! Hope this helps!
