Ram 2500 with engine noise.
 
I've had my Hemi powered Ram 2500 since March and I want some clarity on what is acceptable noise to be heard from the Hemi. I've noticed when I drive with the windows down the truck is a rather noisy beast. This is not the throaty exhaust note coming out of the pipe but rather a medley of different noises. One I assume is the "Hemi Tick" I've read much about. Another is the intake making a sucking noise while under acceleration.

However, the one that really irritates me is what I would describe as an exhaust noise that comes from the middle of the truck. It's a weird noise that only occures under a load. It mimicks an exhaust leak but without a leak. If my truck is running and I place the truck in gear the noise will start. I've even heard it while the truck is in park but the A/C compressor kicks on and puts a slight load on the engine and you hear it. I'm guessing the noise is coming from the exhaust prior to the muffler. My dealer had the truck and they state it is normal "hemi" noise. I've thought that it may be due to thin exhaust piping allowing noise to resonate through the pipe wall and subsequently sound like crap.

Of course when driving the truck the noise is pronounced only on acceleration. While coasting or revving the engine without a load will not cause the noise. I dare say it almost had a diesel clatter sound to it when accelerating.

Any suggestions?

Hi I just signed on today and I'm new at this. if i'm reading the date right, this was posted in 2010. i realize this was 2 yrs. ago, but was wondering how you made out with this noise. I have a 2010 2500 with a hemi and am having similiar noises. Mine have been getting progressively worse. It started out that it was just on start ups and would go away, suggesting the notorious exhaust leak and broken manifold bolts. It now lasts through all my driving. After start up and the idle drops off, it can be heard as an exhaust leak, what I always describe as a 'whiffle'. Then when in gear and backing up or driving forward it is much more pronounced. i can hear it on the highway, when I let off the throttle and then get back on it. it is now a loud tick. i liken it to what I read in someone elses post as 'a diesel knock'. My dealer has also given me the 'normal engine noise' sermon. Also a mechanic told me it was just the exhaust warming up, except I drive 25 min. to work and I'm pretty sure it's warmed up by then. I didn't pay $50,000 to have a truck that sounds like a 90's Ford diesel bag of shit. Does anyone out there have any info. for me? Thanks.

exhaust noise
 
I also have this exhaust like ping sound under load. Does anyone have a fix for it. Its really loud under load and quite annoying. My truck sounds like crap and the dealer is aware of the noise but don't know where its coming from. Im actully thinking of going the buy back route through arbritation. its called camvap or something in canada isnce we don't have the lemon law. Also does anyone else 2500 hemi make a fairly loud creak nosie when going from park to reverse or drive to reverse? Mine does and again they cannot find what is casuing this. They replaced the drive shaft but it did nothing.


im suprised that more people with this truck aren't complaing about the exhasut leak noise more.

Any of you guys get this issue resolved? I've got the exact noise on my 2013 2500.

I have a 2014 2500 w/5.7 Hemi and have been experiencing the same noise since the day I bought it. I've taken it to the dealer 3 times for the same issue, only to have them: update my computer the first time, tell me it was the normal Hemi noise the second time, and the third time I asked them to check for an exhaust leak and the senior mechanic told me it was the manifold "heating up." I call BS because like a previous poster, I can drive 300 miles and the sound is still there. It is really annoying to hear while driving next to a barrier or a curb with the window down because the sound just resonates inside the cab. It sounds like junk, but otherwise it runs like a top. I'm gonna take it in again to another dealer and really make a big deal of it this time.

Common problem on the Hemi's. It is an exhaust leak due to broken exhaust manifold mounting studs or bolts. Usually it's the passenger side manifold that leaks first but the driver's side bolts have been known to snap as well. Haven't heard of the manifold itself cracking but I suppose it can happen as well. I've occasionally seen the bolts connecting the y-pipe to the manifolds disintegrate and snap creating an exhaust leak but less common. Chrysler released a TSB in 2009 regarding this problem and I have known several Ram and Durango owners that have had it fixed under warranty.

Interesting that this problem still persists in the 5.7's and even the 6.4's. The studs and bolts fatigue, rot and snap in two. I suspect inferior metal composition. The TSB indicates that the dealers are suppose to replace the bolts with high strength stainless or grade 5 bolts but the parts guys and techs I've spoken with just use the OEM replacements so the leak will most likely return at some point in time. Not a difficult task to replace them on your own but if they're snapped off inside the head, it becomes more than an afternoon in the driveway.:i_rolleyes:

My 07 2500HD (ordered new) began exhibiting the dreaded exhaust just this past winter. Annoying as hell. I'm ditching the OEM manifold logs and bolting on a set of shorties along with a low restriction y-pipe hooked up to my existing cat-back duals. I love my Ram. Best I've ever owned and I'm keeping it forever. Sad to see these exceptional trucks from Chrysler with some of the most important underhood components assembled using cheap fasteners, just to save a few pennies in the end. I've disassembled decades old 318's, 340's, 440's and the bolts are just cleaned and re-torqued with no issues. :4-dontknow:

Mechanic couldn't find any problem, while he could hear the noise, said everything checked out and to try and get used to it. How could I check these bolts myself? Exactly where are they located?

Reach through the wheel well. You will see a metal shield, which is the heat shield for the manifold. They use common bolts that secure the shield and manifold. Tug on it and see if it's loose. It would be fairly obvious once you tug on it.

Thanx, I'll check it today.
