Seat Click/Clunk Noise Update

So like many of you, I have the same click/clunk noise when getting in to the truck on the driver side bucket seat. Well I finally got to the point where I decided I was going to chase this issue down myself (Since I previously hadn't given it much thought other than letting the dealer look at it). I took a peak under the seat and found that with my right hand in the crack between the bottom of the seat and the back of the seat (squeeze your hand in between the cushions right in the middle) and my left hand on the front that I could rock back and forth and make the same noise. I then moved on to having my wife do this to the seat while I looked underneath and it seems one of the adjusters was loose. The adjuster that was loose was one of the two that make the seat go up and down (10 way power seat or something like that). There is one that lift the front of the bottom cushion and one that does the back. The one that was loose was the back.

 

I took a look at how the motor was mounted to the frame and it is bolted on a slide bolt that has lots of slop in it allowing the motor frame/bracket to clunk/clank around when moving in and out of the seat. I looked at the motor mount for the motor used to raise and lower the front of the bottom cushion and it had a spacer/washer in the place the previous motor mount didn't to take up this slack.

 

So...I ran to lowes to get some 6mm washers and proceeded with squeezing them in place where the slop was in the bracket (Easier said then done with the very limited space).

 

The long and short of it is that it seems to have fixed the clink/clunk/clank noise when getting into the driver side bucket seat. It is also amazing at how much it helped the overall looseness of the seat.

 

I AM NOT CLAIMING THAT THIS FIXING THE SEAT MOVEMENT WHEN DRIVING AS I HAVENT DRIVEN IT YET, BUT WILL REPORT BACK WITH TIME.

 

I will also try and post pictures. I am going to the dealer Thursday to take a look at the seat again (Already had the frame replaced once) and to see if other trucks have a spacer where I added a washer and if maybe they left it off when they installed the new seat frame trying to get rid of the seat movement. (my $0.02 after looking at the seat frame in depth is that the movement is in the actual track pieces used to slide forwards and backwards. The front of the track seems to have spacers between the stationary and non-stationary piece to take up slop, but I don't see any in the rear of the track where the movement usually is.....might have to test that theory out. )

Did this fix it? I have a 2014 GMC Sierra with the AC/Heated seats. I hate the clunk it makes when you move or turn the truck from side to side and it makes you weight shift! The dealer says that they cannot find a noise, I am going to take it in and make them ride in the back seat with a hand under the seat so they can feel the clunk.

Has this resolved your seat issue? I am having the same issue and I took it to the dealership. They put these clips in and it fixed the problem but only for about 2 weeks. Now the dealer is telling me to just live with it. I am looking for a permanent fix to this.

I HAVE 2014 SIERRA LTZ, CREW, Z71 WITH THE SAME ISSUE. MY SEAT CUSHION SHFTS AS MY BODY WEIGHT SHIFTS WHEN TURNING OR ON CURVY ROADS. EVEN MOVES FORWARD WHEN I STOP ABRUPTLY AND BACK WHEN I TAKE OFF. I HAVE THE HEAT/COOL SEAT OPTION AND COLISION AND LANE DEPARTURE OPTION. IT FEELS LIKE THE MECHANIZING IN THE SEAT THAT VIBRATES WITH THESE OPTIONS IS MOVING WITHIN THE SEAT CUSHION. I STARTED NOTICING THIS WITH ABOUT 5500 MILES. NO NOISE OR CLUNK YET. WHO EVER BUILT THIS SEAT FOR GM REALLY SCREWED UP. WHAT HAPPENED TO QUALITY CONTROL. MY HEATED SEATS ALSO DO NOT OPERATE ON REMOTE START.

      What have you done to your K2 today?

      By UrbanRage · Posted

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
