Awe man that sucks. So its definitely not coming from the strut mount area? There are a couple threads out where using the factory strut rod bolt stopped the knocking.

Every night I get a little closer... I have grade 8 bolts in there now. I took each bolt out and still heard the noise but fairly confident the knock is coming from the strut. Need an extra set of hands to feel around to see if we can locate the source of the knocking

Check your top strut mounts and the bolt for the strut piston in the center. Sounds like what our old strut do when they go bad.

Check to make sure the strut it tightened down to the strut mount. Also to check ball joints what you do is jack the truck up under the lower control arm and then place a pry bar or piece of wood unde

Will try that if my crown nut work (see below) doesn't resolve the issue.  Thansk!!!! I checked those yesterday. Cranked the hell out of them BUT I didn't check the crown nut.  I saw some old p

This one. Notice how the thread starts deep with in the nut? That has to account for something.ff100f6c2c9ecf8facdddd5e19bf6697.jpg14261d0e7084a95de6fd454d5ab14746.jpg

Yes. Most of us toss them. But after looking at it I think it pulls the shaft futhure in to the strut mount for a more secure fit.

I’ll check my old struts but for some reason I think my eibach has a wider main shaft. Definitely worth trying thought because I’m running out of ideas...

Main shaft maybe, but bolt holes typically dont change. I wonder if the bolt size is the same.


Tried the nut this weekend it was too long BUT I can see some benefits. The base of the nut is wide and fills the top of the strut plate in well where as the nylock nut from eibach is small and leaves some slop.

Not sure if that’s what is causing my issue but might try to find a wider nut to see if it helps.

Well darn that sucks. Add a thick washer to remove the "slop". Gotta get that squared away. It would really suck to hear those struts failed so soon.

Spoke to Eibach yesterday, I’m going to flip flop my struts to see if the sound follows the strut. If it does they things it’s a failed seal if not....then I’m trading my truck in...

Welp I think i found the culprit!!!! If you watch my eibach install video I mentioned that I previously had a rough country kit. When i upgraded to the eibach kit I replaced the lower bolts with grade 8 bolts of the same diameter.

While swapping struts today I noticed a lot of slop in the lower bolts once loosened. Before reinstalling the bolts I ran to the hardware store and grabbed new grade 8 bolts a diameter size larger (7/16”). Turns out those fit PERFECTLY through the lower strut mount and the lower control arm.

Even looking at the original bolts I had (3/8” I’m guessing, you can see the zinc coating was worn off right where they passed through the lower control arm.

So in short, my lower bolt diameter was too small because I wasn’t using those stock nut clips!

Pictures below showing the wear marks. Crossing my fingers this was the issue!!! I slipped them into my old struts to illustrate my point.

      Brand new to this forum. Questions about re-gearing my 26’ HD

      By BDS my HD · Posted

      Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.

      2013 2500HD 6.0L intermittent no crank no start

      By linc45bn · Posted

      I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated.

      GMC 1500 Illuminated Front Grill Emblem REPLACEMENT.

      By Peoplemvr · Posted

      Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
