Thread: Mazda 626 Vibration

Have you got the wheel alignment done aswell?

Yep ,
wheel balance ,rotated,wheel alignment,new tyres problem still there.


Dash.

Then more than likely one of your shockies is stuffed
Roll into Pedders (or similar) and have them check your suspension
You can check this yourself by pushing each corner of the car down a few times as hard as possible and the stop. The car should not be rocking after letting go.
Another thing you can do is get someone to drive at the speed the problem develops and you sit in the passenger seat with the window down to check the wheels. If you see a 'bouncing' wheel you've found the culprit

most likely your shockies or osme part of the suspension dont go pedders there a frikn rip off and half of em dont know what there on about.just go to your normal mechanic and have them hoist the car up an havea quick look under.However if oyur pedders has the $16 suspension check then go to pedders...

You do not mention that the car is a front wheel drive or rear wheel drive (the 626 came both formats) also are you feeling the vibration though the steering wheel or the body ???.

could be loose wheel bearing.

Hmm z80 could be right, if its a front wheel drive it could be a CV joint also ?

Thanks for the replies,
it's a '98 model front wheel drive.
There's no noise or movement in the wheel bearings and there's no clatter from the CV joints going around corners left or right and there's no pulsation when you apply the brakes.


Thanks

Hi Dash,

In response to your question, some Bob Jane dealers do on car balancing but you will need to ring around, because they are trying to phase it out. They think its too labour intensive.

I had it done about 7 years ago on a mates Bimmer at Moorabbin.

Good Luck

Thanx PPL,
will do some ringing around.

Thanx

Dash.

wouldn't a warped rotor cause a pulsation when the brakes are applied?


Dash.

Yea the more i read your post i don't think its a wheel problem, you say you have rotated the the wheels and had them balanced but the problem persits. so if it was a wheel problem it would show up on the right side of the car when you rotated them, So i would start looking else where for the problem, like rotors, balljoints, tyrerod ends, shocks ??. I hope you find the problem as it sounds interesting.

Vibations.

Everything posted looks right IF a wheel is out of balance, the problem will show up more if a wheel bearing is loose, a shocker worn or a disk is shattered but i somehow doubt that its lost a chunk of disk as you would quickly find that out.

We forgot to mention a worn steering ball joint.

Lets remember that the wheel has to be out of balance to bring on a rythmic pulse through the steering wheel, if its on/off randomly its definitly something worn more than a wheel out of balance.

Another unseen common problem is cheap tyres that have torn cords internaly that feel exactly like a wheel out of balance or driving on a flatspot.
Had a freind ask me to drive his wifes car the other day with exactly the same problem (new tyres fitted 3 months ago) we balanced the tyres and it wouldnt go away.
New tyres did the job.
A balance will not normally show up torn cords that bind the tyre together internally.

One last thing that may be causing a vibration is the tailshaft out of balance of worn/seized universal joints. More commonly a worn seized universal joint but it will be a vibration from under the seat through to the rear of the car.

Bro i did mention ball joints and its a front wheel drive car no tail shaft, and the fact that he has rotated the wheels should have brought to light a faulty tyre.

Sorry tagg your right, my mind is in another world atm. LOL
My apologies.

Oh forgot to mention a bent rim.

If the tyres have been rotated and the cords a buggered in more than 1 tyre the problem will persist after a rotation.

Heaps of cheap chineese import tyres failing atm due to cords breaking.

The thing is he just says he has a vibration, but does not explain how he is feeling it if its coming from the body it could be a harmonic balancer or Fan ??
But if it coming from the steering wheel it has to be wheel or suppension ??

Tagg

A balancer or fan out of whack will come through the body and alter with RPM.

Id jack it up rotate the tyre while carefully watching the rubber tread for movement.

While its up id shake the tyre and wheel top and bottom, then side to side for steering and suspension wear.

If that failed id balance and test then change the tyres or test a set from another car.

Suspension or steering wear will not be rythmic, but rather random if the tyre is in balance.

You can have worn steering and suspension but if your wheels are in balance the shake will not be rythmic but rather a shake through the wheel when you hit a iregularity on the road like a small pot hole.

Torn cords feel like regularly rythmic small pot holes on one side of the car if its just 1 tyre.
Just like a tyre thats been locked up with a flat spot.

One other thing that comes to mind is a loose c/v joint coupling, if the bolts are loose their should be a clunk when doing from forward to reverse and a vibration as the assembly is moving around.

Yes more info needed as to the type of shake, is it rythmic or not.
Easy to diagnose if i could drive and feel it.
