    Angry frame beaming

    i have an 09 , 2500hd , crewcab . would like to know what gives gm the right to sell hundreds of thousands of trucks without informing the consumer ( before they buy it ) that they may be spending there hard earned money on a truck that may have issues with there frames. the issue is called FRAME BEAMING , a term that they have named themselves and because they named it , it must just be a normal characteristic of the vehicle .. i have had the issue on the last 3 chevrolet trucks that i have owned , a 2000 - 1500 extended cab which gm bought back after about 8 months of argueing , a 2003 -2500 crewcab which eventually i got rid of in 05 , and now this 09. how can you have a bulletin combining the years from 1999 - 2011 for the same issue and never correct it. the only fix that is used to possibly help the situation is the replacement of the rear 2 cab mounts, which 90% of the time has not fixed the issue. for those of u who dont know what the issue is it is like having one of your rear tires not balance , always a little shimmy in the rear of the truck... i have spent close to $3000 to try and fix the issue myself , bought new aftermarket rims ( xd series rims ) along with new tires , did not fix , new bilstein 5100 shocks all the way around , did not fix , sold new xd rims and tires at a loss and bought brand new factory chevrolet rims from the dealer and new tires ,still did not fix. one of my best friends bought a new 2011 , 2500hd extended cab back in june 011 , truck had the same exact issue with 4000 miles he put on . when he bought truck dealer told him it was the tire get flat spots in them and would go away in a few hundred miles . 4000 miles later he traded it in on a new DODGE. i have informed friends and strangers to not buy gm, hope they listen.....

    Re: frame beaming

    Well I've had many 1 ton crew cabs from the '70s up to the current 2000 model.
    All had a harmonic bounce/hop going down the interstate when empty. Any amount of ballast in the box and truck settled down.
    If that is what he is complaining about I'd consider it a non-issue. Want a nicer ride, buy a car.
    If that new dodge had a solid front axle let us know how he likes it when the front end wears out and starts wandering or suffering from death wobble.
    I've had a few dodges and poured many $$ into steering/suspension parts.

    Re: frame beaming

    Contrary to the delusional GM Fanboys on this site, this is actually an issue with most if not all GM's 1500 - 2500 trucks. We have had this shaking problem with almost all of our company Silverados when empty or very lightly loaded. Sometimes is is subtle sometimes it is very annoying and rattles the whole cab. Our experience has been that is you take it to a GM dealer they go through denial, then "you are the only person with this problem" to it is normal live with it. However if you persist long enough they should fix it for you as it is a well known and understood issue. Apparently they use very inexpensive cab mounts that don't absorb frame flex throughout the frequency range. They can install better mounts that absolutely fix the problem.

    Here are the part numbers from our service records:
    Upper Mount 25791031 Qty 2
    Lower Mount 25791032 Qty 2
    Washer 15854745 Qty 4

    Andretti, I (as one of the delusional Fanboys) have no problem with your fix. I'm sure it's what's needed.

    snowblind, on the other hand, has a problem with your math. You say "mounts that absolutely fix the problem".

    He says, "90% of the time has not fixed the issue." Personally, I think he just wanted a Dodge, and I have a hard time believing anyone would spend $3k on an '09 truck vibration issue. But I have seen stranger(less intelligent) things.

    I don't say the issue has never occured. I can tell you the frequency I came across a customer complaint of it since I started at the GM dealer in 1994 which retails appx 800 trucks a year, and services many more. And I see all the repair orders.

    One.

    PS-I went back and pulled the repair order for our "one".

    Technician notes: Aftermarket wheels and modified suspension.

    I'm not delusional about the issue. The passenger seat back shakes at certain speeds on some roads in my 3500 series truck.
    I just look at it and shrug my shoulders, meh, empty truck. My SRW Dodges rode rough empty too.
    Since the mounts are out there I might pick up () a pair and see if they fit the older body style.
    Mounts break down over time so why not upgrade to a better mount??

    +1..This is a real issue. my '02 Sierra 2500HD does the same thing. 200 lbs in the back doesn't really help. I've lived with it to over 200k miles, but as I am waiting for the MY2014 to come out, I will bring this up in my purchase negotiations, and make sure I find a dealer that will order the better cab mounts and put them on at no cost to me prior to delivery. **If you want to dig into this further, go to the "duramax forum" website. You'll find plenty on this very real issue.

    no arguement there, but comparing a Ridgeline to a Silverado regardless of the EPA/DMV calling the honda a p/u is delusional IMO.

    I've owned Dodge Diesel before, leaf sprung, coil sprung, short bed, long bed, ext cab, reg cab.
    GM crew cabs from a '77 to 2000, gas-diesel, 2wd-4wd, manual-auto, loaded-stripped, SRW-DRW.
    I'll stick with my thought that if you drive your truck empty so ofter the ride concerns you , get a car. Or a Ridgeline.

    We run Silverados and Ridgelines towing 2500# covered trailers and 400-600# in the bed with 1-3 people in the cabs. In this situation the Ridgelines out perform the Silverados in all measurable metrics. I personally prefer the look/image of the Silverados so we continue to split the fleet.

    I believe he wants to have the new/better mounts installed on the new truck he is going to purchase. That way it will ride properly from the start.

    Although the original post was confusing and poorly written, this response is very informative, logical and well written. Thank you.

    I can attest to the fact that the cab mount bushings are not upgraded on 2011's. If they are using the better mounts on 2012 I wouldn't know as we won't be getting any 2012's until June -July.

    Fair enough andretti (nice objective comments, btw).

    From what I have read on other googled threads, the parts necessary for two mounts, was @$120 (no labor). So even if we double it for four mounts in total, and add for labor, how much has your company been charged on a per vehicle basis?

    Surely not $3 grand.

    You are correct! The only vehicles we actually paid to have corrected were each less than $650. After those we had each of the others upgraded at the first oil change, so still under warranty. However, if we had done all of the dealer suggested fixes (tires, wheels, shocks), it most certainly would have approached $3000.
