Shake when towing

[jbgrizzler]

2017 Sierra, tow package, 6.2 Lt, 8sp tranny and 3:42 rear end. 5000km on truck (3000 miles)

 

Took my boat out of storage (2003 pro sport 17' Lund walk through fishing boat) this past Sunday. While on the highway A very noticeable shake started throughout the truck at about 100-110 Km/hr (60-65 MPH). Towed my snowmobile trailer this winter when the truck was newer, ran up and down highway since Ive had it and never a shake. I have read up on the chevy shake issues in the past years but never read anyone stating that the shake occurred specifically when towing. Mine is only when I towed my boat which is only slightly heavier tongue weight than my sled trailer. Curious what some of you think or have experienced and what The fix was...????

I would venture to blame the trailer tires if it only happens when towing and only your boat

Trouble agreeing with that one. Has never ever happened with any other truck and that boat would have to shake like a bitch to be able to shake the truck like that.

Tires could be flat spotted. Easy enough to test, have a buddy tow the boat with his truck.

I agree on the trailer tires, you just took it out of storage.

I'll take it back out shortly, run it for 25-30 miles to get the tires warmed up and see what happens. If it still shakes I'll borrow buddies truck and te-try. Hope is just the tires. Had the boat and trailer for 14 years now and this has never occured... interesting. Let y'all know. Thx

Replace the tires on your trailer tires NOW. That happened to me (Lund Tyee 1850) ignored the shake and BOTH trailer tires blew in the middle of ST Paul MN.

Haha. Ya no tires aren't 14 years old.

Start with the trailer,,,, Check the wheel bearings.

 

Then I would try and tow someone Else's heavier trailer to see if it's still there.

Well y'all were 100% accurate. Took it for a 25 mile journey. No change in shake. For hom put the old spare set on and shake gone! In 14 years of storing this boat same place same way I have never had this issue. Thanks all for your input!

Keep those old tires as your storage set. Put the good ones on when actively towing.
