I cant figure this one out so I will ask you guys for some help

my car is shaking in the front end, the vibration coming through the steering wheel when I:
a: accelerate from easy to hard, this also now induces some serious torque steer which it never did till this problem
b: hit a bump on the highway cause some good shaking through the steering wheel also wont stop shaking, it totally throws something out of balance. I have to slow down below 80 to get it to stop.
c: when I am on the brakes: rotors and pads are brand new and not warped, I cant see them causing shaking when I hit a bump anyways
and the front end also feels rather loose now.

Waht I have had tested: all 4 tires have been road force tersted and all 4 are fine, all 4 have been rebalnced 3 times now on top of that. all tires have been rotated. the brakes are fine. everything is working fine. I have had the car jacked up and everythign feels tight in the suspension sector.

I had an allignment done about 2 months ago when I got my lower sub frame replaced.

I currently have 101000km on this car and my mods are front and rear ttr inserts for the motor mounts they have been in for about 10000km and lowerin springs which have not gave me any issue at all and they have been on for 50000km.

this problem came out of nowhere. i have no idea how it started or anything, I never hit anything or bumped a curb. i slowed down to 80 one day and it apperead.

thanks for your help.

 

all your lugs tight? if so i would crawl under there and start looking for loose steering linkage.

 

Have you checked the axles?

 

take it to the dealer if your under warrenty

 

Slow down below 80??? Jesus, how fast do you normally drive?!?! lol

 

He's from Canada. That'd be KPH.

 

ya, kph, lol. sorry. lug nuts are fine, all torqued properly and in sequence. how do I check axles?

and my warrenty is done, and the dealerships never help me anyways.

 

Did you bounce off a curb? Anyway jack it up and put it in gear and just watch them for vibration. Also look for any missing weights. They will have left a mark where they were. Also since your in the frozen north look for any ice built up anyplace cause that WILL do it too.

 

what kind of tires do you have cuz i had da same problems when i had the tripletreds but when i replaced them with michelin pilots it was fine..

 

never hit anything, just happened while i was driving, I had it in +10c and i have it in -20c so it doesnt depend on the weather.

 

Well seeing how freezing is 32 degrees it looks like its been frozen a looooong time.

 

he is from canada, 10c and -20c is celcius. 10*c is somwere between 50-55*f. -20 is around 0*f.

 

It was a joke.

 

mine did that its the master cylender haha ya didnt spell that right owell but ya it took chevy 4 times to find it but ya thats what it is
