I have an '06 Cheyenne - 1500 4wd(hence the name). I recently had the RR shocks changed under warranty for prematurely dying (13k miles). The problem at the time was every bump I hit, the entire truck shook like an SOB.

Now it's been 1 week, and the problem is back again.... any ideas?? Could it be the front now?? Maybe I should get the torsion keys and level the front off? I was thinking maybe a root cause could be excessive weight on the front end.

 

For those of us in the U.S the Cheyenne (Canada model) is called the Silverado here.

What have you done in the way of modifications to this truck (list everything that is not 100% OEM)?

 

Not OEM: E3 Plugs, Step bars, Optima Yellow-Top, K&N.

No mod's to the body, suspension or steering.

 

Do you have something hanging on the front end?
You mention "excessive weight on the front end".


Side note: Did you notice any difference after replacing the plugs with the E3's?

 

There's nothing added to the front. Everything is OEM. what I mean by excessive weight on the front is the fact that stock Silverado's are lowering in the front, thus more weight is over the FR suspension, even more so when braking. The roads in Quebec are by far the worst I've seen out of MANY states and provinces. So bad in fact that the gov't made a law that you can't sue them if your vehicle is damaged from the road, i.e.: large pot hole bending a shock shaft from over extension (happened to me on a 92 Blazer FS).

E3's, TOTALLY AWESOME. I noticed a throttle response instantly. Feels like a bit more power as well, over maybe just more getting to the wheels and not lost out the tail pipe. We'll see soon if I save any $$ on gas. They claim 1-3 more MPG. I certainly recommend these plugs. At $6.95 each, you can't go wrong. Heck, AC Delco Platinum's where I am are over $18 a pair. Imagine the Bosch +4's....over $30 a pair.

 

Kind of puzzling to me, what does the dealer say about the problem?
Have they driven your truck?

Were the bad shocks leaking fluid?

 

The RR's were not leaking when they changed them. They drove it yesterday and are going to check the torsion level. Personally I think the FR's are dead.

It's in the garage today so I'll find out this afternoon what the problem was. They've already tightened some parts in the steering system. And that was only 3k miles in.

 

Well it's been in, been out, and it seems to ride better. From my understanding, they raised the ride height to see if it would help (apparently worse). Then it was lowered back down to spec and that was about it. Everything is tight, aligned 100%, no leaks.....Very very strange. They said they were going to change the shocks, but it's hard to tell if they're new or not. Would they reuse the shaft covers? The shock looks new, but the shaft cover is older and dirty.

Anyways, the rest of the vibes are standard pick-up issues, but the bad stuff is gone. let's just say that a good pothole would make the front jump left or right. It was like throwing a rock in a pond, where the rippling starts in one spots and finishes in another.
