Again im new to this forum and Im a new owner of a 2003 Lexus GS430; the question I have is when I seem to drive on a road that is uneven or grooves in the road the car pulls similiar to having large wheels on a car. I went to a local shop that works only on foreign cars to have it wheel aligned and wheel/tire balancing and it still does the same thing.....I need some help also keep in mind the Lexus is totally stock with the fsctory bridgestones 235/45/17 and less than 39k on it.

 

Make sure to check your ball joints and control arms

 

Thank you for advice I called them and explained to them what the problem is and they notified me that on heavy trafficed routes such as rte 9 where large truck travel on can cause those grooves in the road and those grooves will cause the car to pull, etc. The pulling only happens on uneven surface if I took it to lexus would they align the car any different from them??????

 

IMO have the suspension checked and let it go. I get road grab all the time but I'm running a pretty fat set up both front and rear. If you don't anything bump or grind and you've had a professional check the suspension, just concede the fact that you'll have the issue.

 

If the road is uneven then you'll get some pull regardless of what tires you're running or how well the alignment is.

Take a detour, haha, good luck

 

That's normal and to make matters worse, if you have a wide tire the more pull you will feel. Keep a firm grip at 10 & 2 and you will be fine.

 

took the words out of my mouth

also, correct me if im wrong...pulling has nothing to do with balancing the wheels. only on vibrations

 

My car went in for alignment a couple of months ago and drives straight if I were to take my hands off the steering wheel. That pulling whether it be to the left or right does still occurs when I drive on roads where the asphalt appears to be sunken in. Its not really a pothole or sink hole though.

 

Correct, un-normal pulling mostly comes from bad tires or alignment being way off.

 

nvrm...i thought you had aftermarket rims

 

Might need to have the steering rack bushings replaced and/or tighten the steering rack.

 

Participate in your local government and get the roads repaved.

 

Depending if this occurs all the time or just at certain roads. If all the time then your alignment is off or bad tires ect ect. If this just happens on certain roads then that's normal.
Word of advice...JUST DON'T FALL ASLEEP BEHIND THE WHEEL

Hey, I know what your talking about. I installed my daizen rack and away back bushings, it helps noticeably. However, where I live in construction hell, there's like 200+ road construction projects going on under MNDoT. It's either winter or construction season , however I have never been a car that is so sensitive to uneven roads as I drive an LS, LX, a 5-series beamer, explorer, escape, and even my girls Accord doesn't pull and move around in the lane while I happen to driving on uneven pavement or going back and forth. I feel as it wasn't like this when I bought it, however it's been 2 years now since I bought my GS. But even my friends GS is similar, and he didn't even tighten his rack, and he has 16's with brand new tires. I am willing to just deal with it, because I have yet to see someone on the highway who can keep up with the GS, and drive it 24/7/365.
Question: Why do people come on here and give stupid answer's as no one wants to hear an answer like take other roads. If you don't wanna answer with a constructive answer, don't answer! I think he could probably figure that one out, but sometimes that just not another option. It isn't like all roads around here are even, except the one I take. Just my 2 cents.
