The key question here is: why weren't you making Mrs. Econometrics drive the minivan?

? We had $5500 of (warrantied, thank God!) work done on the suspension, so I needed to make sure the dealer got it right. ?

That just sounds more like something that would be happening in the minivan.....

I never had but a friend has. Had to replace shocks. I would look at the Bilsteins.

Are you are running truck 'unloaded' and have factory tire sizes at the pressures on the door sticker? 

 

If so try running reduced tire pressure - its a free trial.

 

Washboard road has always been a issue in a pickup -- especially unloaded and at speed. 

Suspension adjustment -- by setting tire pressure match current loading -- can help.

I have a 2019 Sierra SLT 4x4, and I lived with the crappy ride for almost a year. I noticed the same thing, it would go sideways when going over bumps, lose rear traction easily, etc. I installed new Bilsteins on the rear about three weeks ago - best $200 I ever spent. The ride is much improved on all less than perfect surfaces.

 

As others have said, loading up the rear with several hundred pounds and/or reducing tire pressure can help (I tried both) but neither helps nearly as much as getting the junk factory rear shocks out and replacing with good ones.

A LOT of us have this issue. It's very well-known. 

 

Adjust your tire pressures down some, it helps. The shocks will also get better as you put mileage on them. 

 

Best solution, though, is to replace them with either Bilstein (not out yet) or Eibachs.

I just put Bilstein 5100s on the rear of mine today. I haven't driven it yet.

There is now a 5100 for the front but no one has it yet. Part # for the front will be Part Number: 24-293297. The rear is Part Number: 24-293471.

I've driven a truck on washboard dirt roads since before I was legally old enough to do so and every one of them to some extent will do that, and the longer the wheelbase the move pronounced the effect. Trucks are made to haul stuff and when the bed has nothing in it they will tend to get a little "squirrelly", they certainly make shocks that will help but as mentioned a cheap fix it to put something in the bed. Doesnt have to be much...back in my wilder days even a igloo full of ice and beer makes a big difference lol.

I had the same problem on my F150. Bilstein 4600’s fixed it. Can’t wait until they have the 4600’s for the new Sierra. Hate that feeling.

Thanks Guys for all the help.. going to see if the dealer will help  Thanks again .....

They won't be of any help. You need new shocks to get the more planted ride you're wanting (and should come OEM off the lot!) 

 

The other day I was following Mrs. Econometrics home in her minivan, she was driving my RST. I was watching the rear suspension on my RST... wow... it was just bouncing up and down like a loose noodle. Someone with a TB was driving in front of us, and I honestly didn't see the same play in the rear end. Then a GMT900 1500 CC drive along side my RST for about a mile... same thing. Rear axle just did not look as bouncy. Made me realize how badly I need to get rid of these Rancho twin-tubes.

      The Peckish Synapse

      Well that book won't sell many copies. Taking ones right foot off the loud pedal never gets applause. Funny really, It isn't that people don't know what to do...they just don't want to do it. But they will complain about it. About bad craftsmanship, about the cost of fuel, about the cost of part and repairs and mainly they complain that the solution while still possible isn't one they are willing to do.    I observe this daily. 'Gas cost to much!", they wail, while they mat it passing at 80+ mpg and scoot down the road like gas cost a dime a gallon. Then complain about the few that will lift and save both fuel and iron like they are owed and own the road.    Good thing they haven't an ounce of influence on my equipment. The rest I just laugh at. Stupid is as stupid does, right Forest?

      Gas Prices

      Today I filled up with 4.899 gallons of fuel at a cost of $4.899 a gallon. $24 bucks. 290 miles. 59.2 mpg. After my 4% COSTCO discount just under eight cents a mile.

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      Brake Pad Warning Message

      By TrueBlue · Posted

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.
