Wheel still shakes after balancing???????

ImBack · 12-04-2006, 02:32 PM

Well i just switched from my summer wheels to my winter rims and tires. My summer rims and tires were fine came balanced and everything this june. No shaking what so ever. Switched to my winter rims and tires and it drove fine until i reached highway speeds of 60-65 the wheel starts to shake it would go away alittle at say 80-85 but still shook. I had the wheels balanced and thought that would ake care of it...it did but just a little the wheel still shakes at highway speeds...pressure in tires is fine...what the hell is going on???? it cant be alignment casue the summer wheels and tires rode fine no shaking at all???????????

you could have warped rotors.

**SWortham** · 12-04-2006, 03:49 PM

There are a number of possible causes for this. I'd check to make sure the wheels are not bent and the tires are not out of round or flat-spotted. A lot of times you can check all of that by jacking up the car and spinning and checking each tire and wheel visually. Or this could effectively be checked at a tire shop by doing a roadforce balance on a Hunter GSP9700. You can find a shop with one of these machines by using Hunter's locator here:
http://www.gsp9700.com/pub/search/findgsp9700.cfm

Just make sure you request a roadforce balance, because if you don't ask for it they'll only do a regular balance.

I'd also check the placement of the weights on the wheels. Are these wheels stock or aftermarket?

On the stock wheels, there should be a weight on the inside and on the outside lip of each wheel and it's easy for shops to get a good balance like that.

But with some aftermarket wheels that you may use tape weights on, you'd want the two lines of tape weights as close to the inside and outside lip as possible. If they are not placed far enough out on either side then there's a good chance that whoever balanced the wheels was not able to obtain a good dynamic balance. This is something you should ask about when you have them rebalanced; if you don't, the next technician could very well use the same line placement thinking it was done that way for a reason.

do the wheels fit tight on the hubs? if not maybe they are a little off center causing them to shake at higher speeds.

stretch · 12-04-2006, 04:26 PM

Like bickford says, I'd bet you have wheels with the wrong hub bore, causing the wheels not to be centered. I just went through this on another car- exact same problem.

Maybe so. Then again with my last car I went through 3 different sets of hubcentric rings and multiple rebalances but that didn't solve the dreaded wheel shimmy. The wheels were just in need of a proper balance.

But if you do have aftermarket wheels then it's probably worth it to buy hubcentric rings. If they don't solve the problem then at the very least they may prevent problems down the road.

By the way, I recommend the hubcentric rings from Discount Tire Direct. They're machined aluminum and seem to be made to more precise tolerances than the others I tried...
http://www.discounttiredirect.com/di...riesWheels.jsp

If you let them know what car you're driving and what wheels you have, they have nearly everything imaginable in their database and they can tell you what size hubcentric rings you need. When you install them, just apply some anti-seize to the mating surface so they'll be easy to take off when you want to.

ImBack · 12-04-2006, 05:25 PM

You mean spacers? I have spacers on the car right now.

**SWortham** · 12-04-2006, 05:34 PM

They're two different things.

Wheel spacers are designed to extend the offset of the wheel...

And hubcentric rings are designed to center a wheel on a hub...

bickford · 12-04-2006, 05:34 PM

Its a ring that fits inside the wheel so that it fits tightly on your hub. A lot of aftermarket wheels will fit multiple cars, so the inside of the wheel could be too large for the hub, which will let the wheel sit off center.

The problem could also be the spacers, were you running them with the factory wheels also?

ImBack · 12-04-2006, 06:35 PM

Well when i got the car in dec of 04 i got these wheels with some all season tires...the ride was smooth no shaking...and yes the spacers were on since day one...spring comes winter tires and wheels come off stock bbs's and potenzas go on spacers come off and so on and so forth...last fall after i put them back on i noticed that they shook. I looked at them and saw some weights came off some of the tires. I had them balanced problem fixed no shakes. winter over new rotas and falkens go on summer over last week comes and the winter rims and tires go on...shakes like a Bansheee after 60-65mph...get them balanced...still shakes but not like a banshee anymore. no clue...could it be that i didnt rotate the tires from last year and this year that last years front right tire is again this years front right tire and last years front left tire is this years front left tire and so on for the rears. Should i rotate the fronts to the rear? Would that be causing the shaking. I dont think i ever rotated them in the 3 winters theyv been on...the rears have more tread then the fronts do???????

bickford · 12-04-2006, 07:01 PM

If the tires are wearing unevenly, then that could be it. But if so, rotating them now might not make a big difference because they are already uneven. You could try it out and see what happens. When you tighten your lug nuts down are you using a torque wrench and making sure they are all the same? I doubt it would cause them to shake... but I guess it could be something as simple as that.

fuzz · 12-04-2006, 07:10 PM

Go somewhere with a nice balancer. I would recommend one with a road force. See how many lbs it road forces to. I know at the shop I work at if it shakes we fix it no matter what. There are a lot of things that can make your car shake. I say take it back.

**nhsilversti** · 12-05-2006, 07:02 AM

put the right front wheel/tire on the rear drive and see if the problem is still there. if it is then do the same with the left side. recheck. if it clears up the problem you will be able to isolate it to 1 wheel.

ImBack · 12-06-2006, 03:37 AM

Do you think i need new tires anyway? I did the penny check thing and on the rears the tires are ok lincolns head is covered up but on the fronts its only covered on the middle part of the tire barely & near the sides its not you can see all of his head...with a little cracking also on the side tops

Yeah, it sounds like you're due for new tires. Winter tires don't do you much good when they have so little tread.
