Well my 2019 early build leaker was replaced with 2020 hopefully not leaker. No signs of an leaks on the window or headliner of the 2020 so fingers crossed. Very impressed with the 10 speed after th

No leaker here so can't do a 100% verification, but the problem seems to be with the spoiler design, regardless of weather the sealer leaks or not, and any cracks in the trim make it worse.

Do you do it yet? Washed the truck this morning and checked. No leak. 

So, it's been over a month since you installed this and no leaks? 

 

Must be leaking from the spoiler bolts and running to the top of the window from the inside.   Goin to order this and try it myself!! 

 

FYI- I ran a similar rubber seal between the window and window frame on the outside, across the entire left side of the window and it didn't stop the leak....so I think it is coming from the spoiler bolt!  

 

Washed my truck yesterday and it's still dripping inside on the driver's side, at the plastic piece on the top of the window, still just a few drips but dripping nonetheless! 

 

This picture was a few months ago, but that is the spot, right on the corner of it!

 Yep did it a couple months ago but the truck is parked in the garage, my wife and I are both working from home and it hasn’t rained much. Can’t guarantee it, but so far so good. Worst case you’re out $15.....

Update on the Trim Lok. Had a few days of rain here and no sign of leakage. I highly suggest you give it a shot. $15 and about 15 mins worth of time.

I ordered this exact Amazon Trim-Lok product, but I cannot get it to fit into the upper gap of the spoiler.  I even tried lubricating it with some silicone spray.  How did you guys do it?

I just put it in yesterday...I'll keep you posted.  I plan on water testing it instead of waiting for rain.  Full disclosure, I don't have a leak since they replaced my rear window.  This is more preventative.

I used interior plastic trim tools to get the cord between the spoiler and the cab.  Gap was that tight on my truck.

Anyone that's had the window leak fixed under warranty via a dealer, have you noticed an interior rattle after the work was done? Apologies if this has been brought up. Tried searching the posts but no luck.

Mine was repaired last week at a reputable dealer where I purchased the truck. Noticed this morning on my early coffee run with no music, etc a distinctive rattling on any little bump I hit that def wasn't there prior. I'm hoping it's my son's car seat and/or something he left in it, [emoji1787]

2019 LTZ 4x4, 6.2. For reference.

I used the handle end of a plastic frozen yogurt spoon to work it into the gap.

Might be the headrests on the backseat.  Do a search for it on the forum.

Same here, small drip, just about not noticeable but found it after a serious hard rain.

Headrest rattle like others said before, easy fix to just spread the headrest legs out

OR

Rear cab vent(s).  Check to see if they didn't knock those out.  I got mine back after the window and the driver side cab vent was loose. 

OR

Could possibly be spoiler attach bolts.  I personally feel that this might be a big part of the leaking problem, as my window wasn't cracked...but they insisted on replacing it anyway.

When they did, the leak was worse, and in a different area because they didn't seal the spoiler attach points.  What a mess.  Still have a noise in the cab during extreme temp changes...and I believe it is due to the spoiler not torqued correctly.  Which led to the leak.  Just my theory.  I am probably way off the mark.

Yes I had the rattle. Pulling the headrests and “widening” the bars did the trick. Hopefully I can just enjoy my truck now. No leaks since rear window replaced.

Wow that is considerably worse than mine. They discovered a foot of sealant was not applied at the factory. They ordered me a new window regardless.

Mine is getting worse too.  Doesn't even take much moisture anymore.... just a light rain and the interior is wet. 

 

They discovered a foot of sealant was not applied?  Is that new info?  Source?

      Fluid Change Questions

      By Chuck FB · Posted

      There would be one way of determining the quality of the factory oil although probably more than a typical oil lab test, and that would be to draw out some oil from a new truck and send a sample to a lab that could do a more elaborate test of the oil. The issue with too little oil in the diff may not be the lack of lubrication of the diff bearings and gears themselves ( although a lack of oil volume for cooling ) but the wheel bearings because at some point the oil would be too low to properly get onto the spinning axle or fed along the axle tube. That was the claim by the local dealer from a couple of trucks in recent years that had the wheel bearings fail and they figured from lack of sufficient oil due to a severe underfilled diff and some of the bearing material made its way to the diff and it got damaged as well so the axle housings were just replaced on warranty. But your right that if the diff is over filled by whatever margin that it causes more churning of the oil than is desirable and that is no good either and can cause a pinion seal to leak. Also old oil I believe can tend to loose some of its properties like antifoaming and another good reason to change the diff oil every so often.

      I would be surprised if the diff's were not filled (with the cheapest gear lube) at the axle factory before being shipped to GM.  If you ever watched them building trucks they install the axles and all suspension parts with the frame upside down and then turn it over before its time to install the engine.     Too much gear lube in a axle can be worse than not enough especially with a lower quality GL where is get whipped up with entrained air (foam)  weakening its ability to lubricate.

      This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.
