  • Shaking at 60mph

    When i bought my lifted 2015 gmc duramax i notice it had shaking at 60mph i can feel it good in steering wife said she could feel it in passanger side not the death wobble as they say but a good annnoying shaking only at 60 well before i decided to look into that problem i deleted everything and tune it then i bought ppe tie rods thinking it might fix it but when i put it on tierod on passenger side i notice it was very close to frame so didnt think nothing of it untill i test drove it after new tierods where on and alignment ... still shaking so next i change out idler arm and pitman arm of course idle arm was bent cause tierod was almost touching frame well after that the shaking was gone but need alignment again but once i got alignment done the shaking is back not bad as it was but u can notice it ...now i can grab my ppe tierod and have movement clockwise and counter clockwise my question is the outer tierods can they already be bad? I pay a pretty penny for them want to say maybe 4 months old maybe the shaking mess them up idk i know my truck isnt going to run smooth like a Cadillac but my last duramax did on same tires which is 35 but different brand and before i started replacing steering components i did do tire balance and rotation

    i been on a shutdown so havent really been under truck just wanted to know if it sounds like tierods could be causing shaking at 60 or something else

    Have you already ruled out the wheels/tires causing the shaking? What kind of tires do you have and what condition are they in? Have the tires been balanced and/or road forced recently? As for the tie rods, it should pivot a little if you are grabbing the body and trying to rotate it.

        I'm guessing you already checked the rest of the front end parts like the bushings, wheel bearings, steering box etc.? I know you said the tires were balanced and rotated, but do you recall if they had an issue balancing the tires or did they balance out fine? A road force balance would let you know if there is an issue with your tires. Otherwise if you have a friend or family member with the same lug pattern, try swapping those wheels/tires on momentarily and see if the problem goes away. It sounds a lot like a wheel/tire vibration.

            Toyo or Nitto tires are what we would recommend. Just to name a few, Toyo Open Country ATII, Toyo Open County MT, Nitto Trail Grappler MT, Nitto Ridge Grappler.
