Car Wobbles When Driven Fast

Edward · May 8, 2011

Hi Friends,

I own a AE 110 for the last one year. The car is in good condition. Very recently I noticed a noise from the front area when driven in rough roads & the car wobbles when reached 80KMPH. I wanted a complete repair done, so we changed the Rack ends, ball joints & tie rods ( I am not sure about my spellings, please excuse me if it is wrong). And the front tyres are brand new. After the repairs the car is smooth, no noise in the rough surface, but the car wobbles when reached 80KMPH. Till I reach 80KMPH, the car is steady. What can be the reason? Experts please advice.

Before trying anything else, do a wheel balancing first. Should cost u about 500 bucks. Go to a place where they got the proper equipment, like the places in Malay Street.

You might need to get the front wheel alignment done as well. Guess you have got it done after the repair though, reminded just in case.

P.S. Also, might help to get the wheel bearings checked as well. if you jack up the car and try to move the wheel along a horizontal and vertical axis, do you feel any play in the wheel?

True. If the rack ends are changed, wheel alignment also needs to be done. So I guess wheel balancing + wheel alignment (both only for front wheels) should most likely solve the problem.

Hi Guys,

Thank you for the quick reply. I did the wheel alignment after the repairs. But did not do the wheel balancing. will do it & check the wheel bearing also. Please let me know, if you thing there can be some other reasons. Edward

Yes check the wheel balancing and if this still does not resolve the problem, you will need to get your suspension checked. I had the same problem and it was a combination of wheels off balance and worn suspension bushes.

Hi Guys,

A complete check is done by the mechanic on the wheel bearing & bushes they are fine. He also insistes me to do the wheel balancing. I will do it & come baack to you if the problems does not get solved.

Then the most likely cause is the wheel balancing.

I had the same issue with a ae110. Problem was due to the broken wires inside one of the front tires. Changed tire, problem sorted

The guy has already changed rack ends. That particular nut (steering rack inner bush on the driver side) you are talking about, should be adjusted at the same time the rack ends are replaced. If the mechanic hasn't bothered to do that, then my advice is don't go to that mechanic again.

Yeah I was thinking this could be a problem as well. This is not as common as wheel balancing gone wrong. What brand of tyre were you using ?

MkX · May 9, 2011

If you don't see any irregular tyre wear and issue comes only in high speeds most common issue is wheel balancing.

Hi Guys,

Thank you very much for your input, I got the wheel balancing done today. The front wheels were off balanced very much. The reading was 100 / 25 in one side & the other side 85 / 15. Anyway this is balanced today, but did not get a chance to drive at 85KM to check it. Will be able to do it during the W/E. Will keep you posted.
