#193 of 1492 Silverado vibration
May 29, 2001 (4:31 pm)
Does anyone know if the vibration problems with the 2001 Silverado 1500 or Sierra still exist.
I am about to purchase a new truck ( the old 78 Ford is really rusted ) and have some concern about these problems posted on the boards. I really like the GMC drivetrain and interior opposed to the Ford. Like most of you know , a little research goes a long way in avoiding buying inherit design problems in a $20K + vehicle .Thanks
#194 of 1492 According to the dealers,

the vibrations never existed. Other than that, I haven't seen one on a 1500 lately...now the 2500HD has seen some.
#195 of 1492 Sierra shakearu

In reference to post #190 I was concerned about the infamous shakearo problem with the front end at speeds of 35 and 65 mph. I know that extra frame supports were added for the 2001 model year and some changes were made to the steering but GM hasn't put the sliding window
back as a option . It was removed on the 1500 due to leakage and breakage from undercarriage frame flexing from the new designed frame.thanks

It sounds like you have a bad tire try rotating your tires around rear to front.

I drove 200 miles on an asphalt highway this past weekend and did not experience the bounce at 70 mph that I do on the concrete that I drive on every day.
#198 of 1492 Yeah, you've got to watch those surfaces

North I35 out of Round Rock, Texas has a stretch that will make you swear you have a tire out of balance. It is a ripple in the concrete that is just the right spacing that will make it feel like a tire is out of balance at 65. Turn around and go south and the vibration disappears.
#199 of 1492 Funny, Hawaii has the same thing

that causes the bounce in certain areas on concrete highways....

could that be dried "hot liquid magma?"

the cooled magma is smoother than the concrete...and it's free.

I did get some bounce coming back from Seattle on Interstate 90. In fact at about 85 I decided I had better slow down or my guts couldn't stand it much more - kinda like a stiff legged horse in a trot. I was looking at the surface and could see some ripples, probably from trucks. I am not sure if the wheel base is just the right length to amplify this, or whether the shocks are not quite stiff enough, or both. When I get to Calif., I am going to have stiffer front shocks put on.
