Stiffler

I know this is an old thread but maybe the author still looks at it. Where did you make the little tape dams at on the window? and did you have to torque the spoiler bolts down? if so do you remember the torque ratings? Plan on trying this soon hopefully it goes smooth

Thank you for the reply, The brakes should be in good shape I only have 20K on the truck. The U-bolts were new but i'm ordering a new set just for peace of mind. I'm going to swap tires this evening and try it. If that don't make a difference i guess i will take the block out and try it. I think i can get away reusing stock U-bolts for that just to trouble shoot and order new bolts accordingly. I wouldn't think that would change the angle enough to cause the vibration but I could be wrong. Could the transmission cause a vibration like that.

I have a vibration that i mostly feel in the seat at around 40 and up. Strange thing is some days its better than others but its been there a while. I've got newer toyo at3 tires stock size p rated that were just rebalanced a few days ago. Also i have an 1 in block lift with 5100 bilstein shocks. Vibrations seems to have started around 2000 miles ago Have any of you experienced this or have any suggestions on what to trouble shoot? Im thinking its the rear because I dont feel it in the steering wheel. 2020 rst 5.3 8 speed

I have the 5100s on my rst with the 20 inch wheels and to me the ride is stiffer. I feel more road imperfections than with the ranchos but i think the handling is more stable imo. when i would go down the backroad I live on with the rachos it felt like the backend was getting a little loose. I dont have that with 5100s

I love the at4 unfortunately they were no where to be found when I had to get my rst

In hind side I should’ve got LT tires instead of p rated. Just didn’t want to run the added weight. I don’t tow anything more than a zero turn. When these wear out I’m going e rated lol

Thank you!

Any one here running the 115t at3 here on the 20 in wheel? what tire pressure are you running? I got some on my truck and they look a little buldged out at the bottom. Dont know if thats normal for these tires . Thank you If a redundent post plese delete

That would be my step but I think I’ve past the date to do that in my state

I have to take my truck back for the 5th time dealing with the window. They say it’s unlikely a failed window again but the symptoms are the same as before. My question is what are they investigating and has anyone had this many problems with the window. Is it a possible buy back situation? The gm field manager or something is involved as well. Had the truck 2 years 12k miles. If so how does that work? I’m new to having this level of issues with a new vehicle so I try to see what to expect. I didn’t add to the leaking window thread because of this and don’t consider it a window question

How did you go about this? does the motor have to stay in the truck and cut the cables? i"m looking at a solid to put in mine.

2020 rst here. Have had 3 back sliders put in and the newest one started leaking today. I’m gonna let it go awhile then put a solid window in since it’s not to bad . It is not the spoiler but the window frame that cracks. From others on the forum the solid window fixed it

Just picked mine up they got it done, 40 minute drive home and no noise at 73 degrees. Let’s hope it keeps up

Been to two of them and both are pathetic. The next one is about an hour from where I live. The ford and Toyota dealership are owned by the same people. Toyota is good and the ford service dept was excellent Unfortunately I will never buy another gm product based solely on how pathetic the after purchase care has been. I’ll be calling them today to find out why the shaft has not been put in

We’re you trying to write something lol
