09/09 Q/A Session - Jeep Wrangler and Wrangler Unlimited - Page 2

I have another question while there isn't too many posts yet. I understand the whole "It's a Jeep thing", particularly with the quirky sounds the JK makes. One in particular, I haven't been given a "technical" answer for. I have the 6-spd manual. And without fail, every time I change gears, there is a clunking sound when I release the clutch pedal. What is making this sound? Is it the driveline? Even after my entire clutch was replaced (separate issue), it still makes this sound. It's a clunking sound, like metal on metal, as if something is loose? Thanks a million guys!

Hello Gentlemen!

Thank you for making a million improvements in the JK model

I have only one complaint: the folding windsheild. In my TJ's it took 10 bolts to lower it, now it takes 24 (or is it 26?). Man that's a PITA. Was it made cumbersome to intentionally discourage folks from doing it, and are there any plans to simplify the procedure in upcomming model years?

Even making the wipers quick release (as on the TJ) would make a difference- hey that's two less bolts!

The catalyst and O2 sensors are indeed an integral part of the engine management system.

Some folks do change the muffler for a deeper sound...... that won't hurt, but we don't want you to modify your vehicle.

Exhaust is the same as US I am pretty sure.

Wow thanks for the quick reply! The exhaust in my JK was slightly modified, there were 4 cats. 2 are pre cats I think, without sensors - these were removed. Will that hurt? The remaining 2 cats with sensors are still there.... i'm worried now

Does it make the noise with just pedal movement?
Or is it coming from the transmission itself?
Or can't you tell..

Really hard to "guess" a fix without seeing/hearing it ! Come on over for a cold one and we'll check 'er out !

Really, we all would love a diesel option. Any word if the Mopar team is getting any closer to finishing the TJ diesel swap kit we were drooling over back in May?

If you feather out the clutch is it the same sound?
It sounds like the lash in the driveline system if you slam it into gear you may have some clunking noise.

Really hard for us to say - we deal with stock vehicles. Hmm, has it set a fault code?? If so, what is it ?

Yep, when you feather out the clutch, it is the exact same sound. It is like something clicking into place, but because it is loose - it clunks. When it is in gear, and I quickly / firmly press on the gas pedal - it makes a different clunking sound too. Again, as if something is loose...

The additional bolts on todays Wrangler are there to improve the vehicles structure so that we could improve the vehicles Noise, vibration, ride harshness over the previous Wrangler. While it is understood that there is more bolts to take the windshield down on todays Wrangler it was a sacrafice that was made to improve the overall vehicle.

after being on this website for 3 years, it seems that everyday someone ask the question about cold air intakes an how they add HP, MPG, could you please explain why this does not work on a TJ. i would like to use your answer when replying back to the people that ask.

Dubya · 09-09-2008, 04:32 PM

My 07 Rubi soft top leaks on both sides over the door handles. I have had it in to the dealer 5 times now, and none of the things they have done has amounted to a hill of beans. They even repeated a TSB to add some foam weather stripping. Nothing helped, and this is a well known problem.

Someone on another forum reccommended adjusting the sport bars so that they are closer to the doors, thus giving a tighter fit to the door. Does this sound plausible? Is it possible to move the bars (specifically the section next to the door) laterally?

Thanks!

Best guess I have is to look at the clutch pedal itself or the pin under the dash.

No fault code (yet), and it runs fine. It's just a majority of the restriction as with all stock vehicles, is in the cats - as you know. I "was" interested in replacing it with aftermaket Hi flows - but at risk of issues as you have highlighted, I will not pursue it. Thanks again, sorry for crowding the Q&A!

Boy would I love to take it over there and show you what I'm talking about! The sound is definitely underneath the vehicle, almost directly under the shift stick.... or perhaps in the engine bay. Maybe one day I'll upload a video to Youtube, if I can get decent audio from it.
