Wobbly corolla on motorway

Recommended Posts

Hi Guys,

Felt uncomfortable at the weekend during a trip up north, at motorway speed it felt like my stomach wash turning. I made couple of sudden movement steering wheel and it felt very wobble, one of the the passenger said even his little micra does not do that. It appears at motorway speed the car unusually light, going down hill on parts of M1.

Are my shocks gone or are they on their way out? (after 110k miles, non of the shocks are leaking as they are clean and dry.

I did the usual bounce test, but I cant see anything unusual other than the rear is easier to bounce than the front but that could be due to the front is much heavier?

Also, if I need to do the shocks, should I also replace ball joints? Does bad ball joints affect the up/down movements?

Thanks in advance for your inputs

Have you checked the tyre pressures? Underinflation could make the car extra bouncy.

Yes, before I set off, I checked the tyre pressure, all same 32psi or a fraction more.

Thanks

I would have that checked out properly, you need to inspect it, preferably in the air, so that track rods/arms/suspension/tyres can be thoroughly tested. Do you have a local garage you can rely on? If it is as bad as you say then it really should not be too difficult to find

Hi,

Agree with Kingo, do get it checked by a mechanic,  like part of a mot but just on the suspension and steering,  a few pounds much better spent than replacing parts  on a whim.

Are you getting any vibration though the steering wheel or though your feet ?  eg out of balance wheels  or a curbed tyre /bulge.

Checked your wheels nuts , any loose ?

Did the problem just start this trip or only at motorway higher speeds ? what recent works have you done on it ?

No. Only left front tyre wearing slightly uneven on the outer edge -  I hit a kerb I think  some times ago, will get it aligned when I get the set of new tyres.

No, I noticed it in the past as well, I put it down to high winds at that time. It does it at motorway speed 60+ if the road it bumpy or if I make make sligth sudden correct on the steering wheel then it settles down after a bit.

All wheels torqued to 103Nm

Hi,

Sounds like you have damaged something on the steering and / or suspension, probably now worsened with continued use and uneven tyre wear.

Would get the front steering alignment checked before you buy new tyres, but you might also have wear /damage to the rim and track rod ends and/or wishbone ball joints, again any decent garage will check those while doing the tracking /alignment. Check the fact that you will be offered 2 or 4 wheel alignment.

Hi, why not try swopping the front tyres with the rears and see if it changes? Mike.

Did another test on the rear, one side defo moves more than the other. 

I will get it checked by mechanic, although the MOT was just done last month I don't think they do a proper check on suspension, do they?

It may be one of the brake calipers is sticking on a front wheel. Jack it up and spin each wheel. If not then worth the check with the mechanic anyway. Steering and brakes are key to staying safe.
