shaking/ truck feels like its pulling left/right slightly

Chevysousa · June 25, 2015

So i made a post before and everyone flipped out because i accidentally wrote that i drove *140mph*....when i meant to write was *140km/h*..and it was on a highway to pass some stupid

truckers flying back and fourth... WELL thats out of the picture!

my Deal is that when im at about 100km/h. I feel something happening with my steering wheel...somethings not feeling right...like a pulling or leaning like my truck wants to go left or right at

times... And as i said up top when i passed these 2 truckers i gained to about 140km/h and it nearly felt like my truck was damn right going out of control ...yes i know im in a truck! but ive

driven trucks before and never felt anything like that. Now i constantly feel this everytime im going above 80+ km/h. any thoughts of what it could be? im no mechanic so im useless and will

probably need to bring it to a shop or dealership. but i appreciate your thoughts

What are the alignment numbers?

i have no clue all my stuff was done at a local shop. could it be an alignment issue?

morrislee · June 25, 2015

I would get it aligned, tire balanced just to be sure, maybe rotate them if you have high mileage already on those rubber

Chevysousa · June 26, 2015

yeah i only have like 7k on the tires. and i apparently just got the alignment done like a month ago when they were fixing my lift.

morrislee · June 30, 2015

hum.... driving my truck for the past couple of days, noticing past 120km/h shakes too, as soon as it is under 120km/h, it is fine. maybe time to rotate tires and balance them

Chevysousa · June 30, 2015

thanks guys ill be looking more into it.

Let me know if you find out anything, mine is vibrating, I might wanna get a rotation soon and get nitrogen in it instead

Chevysousa · July 2, 2015

ye

yeah still nothing as of yet i really dont want to spend another 100$ when it was just done...so im contacting fabtech thats where i got my 4" lift to see if they know something down the line.

morrislee · July 2, 2015

What if it was uneven wear? could balancing fix that? i have hear my tires burn out couple of times when I floor it from stop, I might have worn them out....lol

yeah i see that there are alot of vibration issues. i dont have nun of that. nore the shake really...now its just like a slight tug to the left/right.....really stumped on what it could be.

Yesterday, it was really good weather, tire pressure were almost exactly 220kpa, no shake or vibration at 120 to 130km/h (faster than I should be on the highway, but I was surprised)

I think the pressure does make a difference. I am going to get the tires deflated and nitrogen the whole thing while doing a rotate and maybe a 2inch block in the back. I like a little rake back.
