Thank you for the well written explanation!

Does this make sense?

I get that you are happy with your ride after the change. I still don't understand WHY it is different than before. I'm getting the feeling you want your truck to ride like your grandpa's old 86 Cadillac. I haul things in my truck and I think the improved ride you are describing is the same as I experience with a bed full of lumber or shingles. I realize that with no weight in the back it may bounce or clunk a bit more over large bumps. For most driving on normal city streets my truck is still more comfortable than the 2 other vehicles we own. But I don't expect it to handle bumps the same way as a passenger car.

Andy,

No use in beating a dead horse with a stick LOL

I use my truck for towing and hauling as well.

If I wanted a Cadillac for a truck, there would be a new 2020 RAM 1500 in my driveway.

The same old issue has popped up again and I'm now seeing more from members here posting about it. Yes, those who weren't helpful are still blocked, I don't want to hear drivel from fanboys.

 

I haven't driven much but I drive on dirt roads frequently in Mexico and out in the desert near Temecula where I run a large ranch. This is the third time it's done that, back end swaying in one direction. This time, it was on a straight dirt road with ripples on it but there were no pedestrians this time, fortunately. The first time it did that, a guy had to jump out of my way. The saving grace was that I was in the middle of an isolated road. If there was traffic on the other lane and I was on the right, I would have hit the pedestrian and that was enough to really piss me off. This was a safety issue and this should not be tolerated by any manufacturer. Roads do get dirt on it, I should not be forced to swerve when the rear end decides to fishtail on its own! I don't want to have to drive ridiculously slow on roads with dirt on it or even dirt roads, especially in a 4x4!

 

Based on advice from others, I reduced the psi on my tires from 45 to 35 which helped. Had coat of spray-on liner to weigh it down a bit more. It did that again but it wasn't that bad, then did it again last week which is pretty much the final straw.

 

I could change the shocks on it. It kind of sucks because I paid extra to have better handling and it's clearly failing in that department. The electric gremlins are annoying but I can live with that. I am not too keen on spending more money on it right now.

 

Yes, it's great, I love the gas mileage I'm getting on my V8. It has a little less power than my previous F-150, but that's nothing when I get much better gas mileage, 18 vs. 24. I like the interior.. although I know some of you don't like it, but I came from the F-150 which had cheaper interior than Silverado, so I obviously don't know what I'm missing out.

 

If it wasn't for the back end swaying and the electronic gremlins, I'd rate the Silverado above the 2016 Ford F-150 I had.

I agree that you will  find your solution at a spring and axle shop. Decades ago I found shocks a cheap, easy option to deal with my suspension complaints and could always muster up "facts" to validate the expense.  One visit to your local spring shop will show you how a specialist can adjust, add or replace your springs to provide a ride quality that is right for your needs.

You guys do realize you both right....RIGHT? 

 

Factory rear shocks, any of them, do not have enough rebound dampening and to much compression. The spring compresses grudgingly the slaps the pavement as the spring rebounds with little resistance. The shock valving needs another thousand pounds to act 'normal'. But anything weight wise will help. Even a few bags of sand near the tail gate. Have a conversation with Ben at Filthy Motorsports if you need the minutiae. 

 

Andy does make on solid point is the word EXPECTATIONS. You can't agree if you expectations differ, eh?

This is the first intelligent explanation of how the shocks work I have read anywhere online.

 

So does this mean that Dan's Billsteins have MORE rebound dampening and LESS compression?

[Wiggums]

I tried about 100 pounds of spray-in liner but that didn't seem to work. I didn't have anything else but I am not too keen on dragging weight when I'm trying to maximize gas mileage.

The dirt road is about 2 miles long with about 1 mile being completely straight. With my old F-150, I went 55 mph regularly on the hard dirt road. The new truck fishtailed at only 35 mph but it didn't do that the first 4 or 5 times I drove on it even at 55 mph. I was going slower because my co-worker was on the side of the road so I stopped to ask him what he was doing.

 

You know, some cars, the wheels are fine at 35 mph, vibrate at 40 mph, then goes away at 45 mph. I think it's the same way with the ripples on the road. I have to be going faster or slower to avoid this. The back end wasn't bouncing around, it was just the right jiggle that really gets it crazy, and move one direction. I can handle the bouncing around but not that.

 

The Raptor and F-150 bounce around too but that's all four tires and I can always easily correct it. I couldn't do that with the Silverado, when I ran over the ripples, I let off the gas and it was quite a bit off again and I slammed the brakes this time with my car winding up diagonal on the road.

 

Nobody else drives less than 35 mph on that road, it's well-maintained with a few ripples from the water coming out of the avocado farm that borders the gravel road.

 

There should be a recall on this, honestly. The three times, I was driving at the same speed everybody else does.

 

How much would the good shocks set me back? I've never replaced shocks before. From what I've read here, the twin tubes are to blame. Two tubes disagreeing with each other. GM should have stuck with monotubes.

 

Sierra Dan explained it perfectly.

So when you are driving with 1000 lbs in the bed, how does your truck handle the same big bumps? Does the rear end float more?

Are you in 2 high when this happens? Maybe use 4 auto or 4 high when not on pavement.

 

Always 2H. I don't think 4x4 would help with the back wheels. All three times, I was going 35 mph. I realized that now. Never happened going above 45 even on the same road. I guess I'll just go faster. I usually go 55 on that road, it's really flat and straight, very well-maintained except for the ripples caused by the water coming in from the avocado farm. I was only going 35 that time because I had just stopped for a co-worker on the side of the road.

My Rancho K2 does it a bit and my '14 non-Z71 4x4 is even worse, but not noticeably more than any other older truck I have owned. I wonder if a Hellwig sway bar would help clear it up. Lots of guys were putting these on the K2 trucks. Kind of funny how GM claims they put 2 million test miles into these trucks and they still get released each year with 15 common major annoyances/problems. Looks like Hellwig doesn't have one for a 2019 yet, but they likely will soon.

I have never had 1000lbs in the bed.

Any substantial weight would calm the savage Rancho beasts a bit more.

But honestly, how many light duty truck owners today travel daily with substantial weight in the bed or have a trailer hooked up?

Well sure Marty.

I do not want my points to come across as arguments but rather experience.

How can you argue with experience?

You're right, the majority don't do that. But I'm glad mine has the capacity to carry more weight when I have my 400 lb plow on the front and a couple hundred pounds of sand in the back during the winter. The ride is very different then. And I am okay with that. You're never going to make a truck ride like a car and still deliver all the capabilities of a truck. Its a give and take, and only each owner can decide what configuration meets their needs best. I guess your needs are just different than mine. I won't hound you any more about it. Have a good weekend!

[L86 All Terrain]

Trucks are designed for payload. They ride stiffer when empty. Today's half ton's payload is rated the same as yesterday's 3/4t's. Now with weight reduction the biggest concern for automakers, they are getting stiffer in the rear and also lighter in weight. The T1 is nearly 500lbs lighter than a K2 truck, I would expect a decent portion of weight savings come from the bed area, even though it was hinged parts using aluminum. Now GMC has taken even more weight off the rear with the Carbon Pro bed. Yes sure, lighter bed means more payload, but it also means poorer weight distribution, and evidently axle rap. Where your 2005 Chevy was a 60-40 front bias weight split, these are probably closer to 65-35, and I would expect the carbon pro to almost approach 70-30. To me, that is probably not the right direction to go for handling, but great for increased payload. They should be pulling weight from the front of the truck to improve payload while maintaining unladen handling.

It's all Good Andy.

I like hearing other opinions.

After-all, isn't the diversity of the members here what makes this site tick and survive?

We can all contribute in our own way.

There are members who own and drive 2500HD trucks that do nothing more than drive 'em down the highway vs. using them for towing or hauling.

Happy motoring to them as well!
