Suspension Noise

Hello All - 

 

I have a weird suspension noise that I believe is coming from the driver's side but perhaps under the driver seat area (torsion bar).  The best way to explain it is the sound a straw makes going in and out of a McDonalds/fast-food cup.  LOL  Even the slightest articulation causes it.  However, I've only noticed it when a little warmer (above freezing) and more humid conditions.

 

Has anyone heard and/or successfully repaired this?  I'll likely take it to the dealer eventually but I'm guessing it'll result in a "no problem found" as it doesn't happen all the time.

 

Thanks.

I  agree unlikely torsion bar. I would start with upper control arm , move down to lower control arm. and eventually each sway bar bushing. One of my older trucks i had a noise. from the  front suspension. fox coilovers and incognito control arms. I carried a can of wd-40 on a test drive soaked each bushing one at a time.  Found  my noise on the 3rd shot. 

 

I also agree it could be a shock the oem ones are not the greatest. might be dust boot might be the the chrome plated shaft running dry

Definitely a bushing type of sound. (Not metal on metal) Only reason I thought torsion was that it sounds aft of the front suspension.  I know there’s been complaints of the leaf springs making noise but I don’t think it’s that far back. 
 

Really hate noises like these because they are annoying and hard to troubleshoot.  
 

Thanks for the ideas!

Leem offered a good technique:  lube the bushings with spray one at a time driving in between until the noise stops. I don’t know if wd40 is a good choice for the materials. I would have guessed silicone spray would be better for the bushings, but I really am guessing. Maybe Leem researched that.

Yes i forgot to mention it was not the old school WD-40 is was the silica based  blue silver can.

I would rinse all of it off after your test. That stuff likes to gather grime.

      seat base height *lowering* (base 40/20/40 seat, 2026 1500 WT std cab)

      By bwiese · Posted

      Folks, Have a great new 2026 WT  (std cab, 2.7/4WD) w/base 40/20/40 mech adj bench "fake buckets"  (with lower and upper center console) heavy vinyl seats.  Overall the seats are very comfortable and the vinyl is heavy and appears less likely to 'split out'. Am very tall (6'5")  + a bad back/osteporosis/former hyperparathyroidism so ease/range of movement is a bit restricted.  The truck rides a bit high and I use a nerf step bar w/my left foot to step in, then I put right foot/leg in, drag my butt in  & get seated.  Worked fine in my 2018 RAM quadCab. But I end up dragging my butt over the left raised sidecushsion area of vinyl seat, and due to texture there's fair amount of traction on slide inward.  (ArmorAll didn't improve.) If the seat were even ~1/2" - 3/4" lower it'd be helpful, but base seats just have the forward/backward underseat bail and the side lever for tilt which really doesn't affect seat height.   I really don't want to 'de-puff' the left side sidecushion forming the  fake 'bucket'. I know one company sells 'seat elevator blocks':  but is there a simple way of lowering the height of the driver seat instead?   Thanks Bill W San Jose

      I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.
