I just put my summer rims and going around 100 km/h, my steering wheel is shaking and when I press the break, the car lean toward on left or right.

When breaking at high speed, the steering wheel is shaking too.
This was happening before but wasn't serious.
but after putting summer Rim, it got worse.

Recent mod was KVR slotted rotor with CF pad.

Could it be the problem?

Thanks in advance

First and foremost, the simplest thing would be to check if your summer rims are bent, or any of the wheel weights have fallen off that could cause the vibration. Check the tire pressure on all tires, more importantly make sure that the 2 fronts are at the same psi.

Also, I cannot remember if your car was lowered, if so did you get an alignment done? toe in or toe out can cause ur car to pull either which way.

As for the brakes, the only logical thing that I could deduct is that hopefully you took it easy on them after we did the initial break-in. if you over-heated them by going hard on them, they could be warped

Oh, was there shaking before the kvr rotors and pads were installed?

hope this helps. Keep us updated

Thanks everyone...

Ken..
The shaking when I was breaking is after the KVR rotor I think...

Shaking at cruising at 100 km/h is after I put the summer rims on I guess...

Where can I check the problem?
any good shops at GTA area?

I just check the tire pressure.. there were no problem.
If the wheel weights are the small blocks inside the wall of the rim, I think some of them are gone from every rims, cause I see some marks that there were something sticked.
Bnet rim... I dont know, when I look at them, It seems fine to me.

So please let me know where I can check this.
Oh.. My car is still under warranty. Can it be covered if it is alignment problem?

Thanks again

Does it shake when you go up to 120km and let go of the gas? does this ONLY happen when you apply the brakes?

that's funny... i was on the dvp today and my steering wheel started to shake a little as well when i hit 100km/h and up...

i just got my new rims on....
ride just got re-dropped... and got an alignment right after.

havent checked the tire pressure.. but i'll give that a check, but even if they were off... i've never had my steering wheel shake at 100km/h and up when they werent the same tire pressure.

as for the rims... maybe the guy didnt balance 'em correctly.......

only logical explanation that wwent through my head was the worn down front lower control arms' bushings that i still had on..... but i dont konw if the bushings would cause my steering wheel to shake at 100km/h and up....

Yes, those small blocks are the wheel weights and if there are some that are missing (which u said u could see the glue residue) then try switching ur rear rims to the front, make sure that the rears have all the weights on them obviously. That way we can at least eliminate the wheels/rims from the problem.

this might also be obvious, but did u torque your lugnuts when u got home?

You can take your car to wheels direct and they can balance them for you ($10 a rim i think). If they are bent, they'll let you know or they will show you when its on the machine.

It shakes when pressing gas pedal around 100 km/h even let go. and also when braking at high speed.

Ken..
Some weights are missing from rear too..(damn)

I will take my car to the Wheels direct.
By the way, I saw ur car at the SCN.. very nice..

Thanks everyone...

Wheels not balanced then.

Even the best of us miss that.....LOL. At least I managed to pull over for mine. And I agree that it's got to be the rims. It's a good practice to have your car realigned and wheels balanced every spring. Of course I haven't done it yet, and my front end is shaky between 120 and 140...not that I drive that fast of course.

make sure ur rims r bolted on tight enough and are tighten to the same amount of lb for each rim, i had the same problem, but some of my rim wasnt on tight enough causing my handling to be really horrible

For the steering wheel shaking look into ballancing all your wheels, as someone said some ballance weights may got lost, causing you to worry.

Allingment will help tire weare, but it has nothing to do with shaking.

Wide tires on uneven road surface = puling of a car to left/right when braking.

Thanks...
Everyone..

I went to wheel direct today and did the balancing on 4 wheels.
Most of the shaking is gone but still there are little bit...
But shaking when breaking is still there...
What do i have to fix now?

Worn brake rotors, uneven brake pads wear, cloged/blocked brake line...
There are few posibilities

Damian, I want you to bring the vehicle up to speed, then push the button on the ebrake lever, and slooooooooooowly pull the ebrake (dont pull it so hard as to make the wheels lock up)

But make sure you're holding the button and pulling the ebrake with increasing pressure. Do NOT push the brake pedal. Do you feel the vibration in the ebrake handle?


If you do, that means that your rear brakes need attention.

umm, the shaking is from the front my fine feathered friend so i doubt that the culprit is his rear brakes. HAHAH i can just see him pulling it and drifting into the wall.

lol oops my bad
i was thinking the pedal was pulsating, i just re-read the thread... its the steering wheel thats shaking
haha nm

i just rebalanced my tires as well........ it's STILL shaking once i hit 100km/h.... it's like a vibration on the steering wheel....

only thing i can come up with is that my bushings on the control arm are worn down but i dont know if that could cause the steering wheel to shake at 100km/h

Did your mechanic checked tie rods?
Thats most likely gives the "shaking".

 
Rep Power: 0

sorry... tie rods?

 
Rep Power: 0

tie rod ends connect your suspension steering knuckle to the steering arm of your steering system. The usual culprit is a torn boot, and u can tell by built up of grease around that area.

A good test is also to jack up the car, and give the wheel (tire) a left and right jiggle, if there is play then that would be a good indicator of a worn tie rod end. While you are there is a good idea to give the tire an up and down (push on top and bottom of the wheel alternately), if there is play then that could also indicate worn wheel bearings.

An obvious thing to do would also to check if the tie rod end nut has been tightened properly

If there is no play then that could usually rule out any problems.

An obvious thing to do would also be to check if the tie rod end nut has been tightened properly.Hope that helps
