I posted a while back about shake in my steering wheel on the highway. Been down the rotate, balance, new tires road and just recently got new rotors and pads. Still going strong with the shake. Would the rims be the next thing to obviously check for dents, etc.? I figured that when the tires were replaced, they might have told me they saw a dent...maybe not. Any further thoughts or things to "look for" would be appreciated. i'd like to take it into a garage and have them check it out, but the more hints I can give, the better. Thanks!

I would get your front axle looked at, recently i had the shakes and replaced my front axle and now it is gone but i havent eliminated the shakes from the rear yet though.

Is there a particular speed where the vibration occurs? A good tire shop should have checked the rims, but that doesn't mean that they did. The newer suspension has less mass to dampen the vibrations, so "close enough" on the balancing isn't good enough anymore. Have the balance rechecked, and it may also be time for some new struts - depending on mileage.

Thanks. And thanks leftd90. All good inputs. Typically once I get over 60 it starts in ernest. sometimes the amt of vibration differs at different speeds - like more from 65-75, less over 75 if that makes any sense. i bought it in jan '05 with 31K and now i have roughly 51K miles on it. love everything about it so i'd love to fix this problem...you just can't drive this car under 60!!

I am having the same problem you are with my 01. I have had the tires balanced twice, front end alignment, replaced the drive side half axle which was leaking, and still have the annoying vibration and wobble in the steering wheel at those same speeds you mentioned. What is wierd is that for 3 days last week (in a row), I had no vibration or wobble at all. Then it magically started again. The tires on the car are almost new Goodyear RSA'*, but I did not purchase them, they came with the car. This whole thing is really starting to **** me off. Some people can live with this, I can't. It takes the pleaure out of what is a fantastic car. Sorry for the rant, just aggravating. I guess the next thing is a Hunter Road force balance; does anyone know if that will tell if the tires are out of round?

it really does take the fun out of it. i love the car so i really want to try to figure it out. my tires are no more than 1 year old and the place i got them was a sullivan tire i believe. my normal mechanic sent me there because he said they had the only balance machine that could balance my size tires properly. i can't remember the name of the machine, but obviously that didn't work. i'll post the tire make and size, but RSA sounds familiar so that'* probably what I have too. i have yet to have a time when the vibration has not been there. it does also seem to sometimes shake more when the A/C is on...or maybe i'm just imagining things now...

Your best chance to get rid of shake from tires/wheels is the Hunter 9700 and a knowledgeable technician. You might buy Michelins and get rounder rolling tires that will eliminate some of the problem. The Hunter technician can check the rims as well as the tires for out of round problems. Plus the pressure on the wheel while it'* rolling tells if there an out of round effect due to crushing differently on one part of the tire/wheel than on the other

For my LeSabre it required a careful alignment. My rear toe in was slightly off but well within the allowed tolerance. But my technician knew it also can set off shaking.

I am almost convinced that my SSEi is unbalanceable. No terrible just a slight quiver. I've had 3 sets of new super high-performance tires in the last 20,000 miles in order to try to solve the problem. No soap! Still a quiver from the front end. Seems worse when cool weather. Sometimes she is smooth as silk and sometimes at the same speed, over the same road, she feels out of balance a little. Have tried Hunter 9700 blanances. No deal! When I flip the rears with the fronts the problem is still a slight quiver in the front. Freakin' amazing! Problem entirely goes away over 75 mph, but 67-75 mph I get that quiver.

I've replace both tie rods. I will admit they were about shot at 65,000. I was hoping that would solve the problem. The tire dealer thought so too. Not. He says the front end is as tight as new. He has told me that he has had consistent problems trying to balance the 2000+ SSEi'*. He thinks it is a suspension flaw in some of them, not all.

Almost makes me want to dump the Bonnie, almost.

My Aurora has the same vibration problem in the front end, and it has 16" rims instead of the Bonneville'* 17", and a different strut. This kind of proves, in my opinion, that the problem isn't wheel, or suspension related.

Soooo, any ideas from the crowd???
