I had my tires balanced, then re-balanced and I still vibrate once my speed hits 40mph.. I had my rims checked for bends/dents, nothing.. Could this be an alignment issue? I have no clue..

Any ideas.

 

Definitely not an alignment issue. Your problem is strictly related to the wheels, tires or hubs.

Question. I see you have aftermarket rims. Did the installer have to use hubcentric rings to go around the hub? maybe when you got your tires balanced, the ring fell off. This will cause the wheel to not sit centered on the hub when you bolt it on. If this is the case, even if your tires are perfectly balanced (off the car), they will not spin true when on the car.

Based on your post, this would be my first guess.

 

was it doing this BEFORE the tire balance at shop??
you had them balanced trying to fix a shake?

any giant potholes recently? big curb hit?

If so- look at all the suspension and steering- axle bearing/cv joints for any damage
Any rubber boots that are torn are a bad sign

 

01tl4tl, you are always on the ball! I completely forgot the CV joint possibility.

A few more questions about the shake...

Does it only shake during load? (When you are accelerating/decelerating)? If so it could be a problem with the cv joints - more likely inner joint.

Does the shaking seem to be coming from the steering wheel or the seat of your pants? Steering wheel indicates front wheels, seat indicates rear wheels.

Does it shake more/less when you are on the brakes?

 

No shaking before I got balanced and rotated.. It started after I got balanced.. After reading the first response, I had the tire shop check for hubcentric rings.. No rings on the front wheels.. They put some on, re-balanced my tires and off I went.. Unfortunately, no fix.. Still vibrates.. Although not as bad now..

When I accelerate, the vibration is not that bad.. Breaking, the vibration is not there.. When I am cruising at 40-60mph, thats when I feel the vibration. I appreciate any tips or possible causes that you guys give me.. I have had these wheels on the TL since January and no problems, until about 1.5 months ago, when I got the tires rotated and balanced..

is it possible that the directional tires are facing the wrong direction? Would that cause a vibration..

Oh ya, i feel the vibration more in the steering wheel than in my seat.. Although, I do feel it in my seat a little..

 

go look at each tire- it will have an arrow for direction that should be pointed to the front -------->

So the rims you have now- I see they are 20s,,, thats big for the TL,
so they DO require hubcentric rings- the size adapter that goes from the hub on the car to the inner connection of the new rims?
Plastic or metal ones?
Did they check all the wheels- if they forgot to install 2 of them- they probably forgot at least 1 more~

 

the other idea would be use a `Hunter Road Force` balance machine, with those rims- a standard machine wont do the job right

 

Im just lurking here...but this doesnt sound right. Unless the tires are all the same size.

nice catch!!! didnt see the stagger-- you young kids with your good vision~

So whats the story with the stagger Duma??
- what tire sizes are you running exactly and where- did the shop do a front to back rotate, or cross x pattern which would be wrong for directional tires-

but if they used a lousy balancer and forgot to reinstall the very much needed centric spacer rings-----you do the math
Note hubcentric rings are removed for balancing- always make sure yours go back on if custom wheels- take the wheels off at home and carry them in is best! IMO

Another scenario- when rotating tires- its possible to have a broken belt inside the tire- potholes are tire killers, especially super low profile ones-
so when you move it to the front for example- now it makes a shake

But I think stluis is onto the solution with the stagger sizes
or the cv axle bearing is the other obvious choice

 

Understand that not all hubcentric rings are the same size. If the shaking was less pronounced after installing the rings but not all gone, they could have installed the wrong size.

 

dude, are you lowered? hard? by looking at your avatar, i'm assuming you are. well, i have the same problem, except for me it's more noticeable under acceleration and mine goes past 40. after inspection via acura of lynnwood - i have either a bent axle (i know, ) or some sort of bent center hub? they put it on the lift, and when the car started going - the front right wheel was WOBBLING. something's bent - i'm just not sure what

 

NO, the wheels are where they are supposed to be.. 20x8.5 in the front and 20x10 in the rear.. Thats not the problem.. I had these same wheels on my 05 Tl (aug07-dec07). Bought 08 TL (put wheels on 08 tl). No problems what so ever until my last rotation and balance.

CV axle bearing? Not sure what that is, but tomorrow, I will take it back and have them check it out and have them check to make sure the directional tires are facing the correct way..

Stlouis, i love your white-on-white.. it looks so good..

 

Nah man, i am not lowered at all.. My avaitor is all photoshop.. I think Saturday i am going to go to the acura dealership and see if they can tell me anything..(if tomorrow the tire shop cant fix the prb).

 

Thanks about my car.

Now with yours, you said that they rotated your tires. Does this mean that they unmounted all 4 of them and put fronts on rear, and rears on front?

With this, the only way this would work is if all your tires were the same.
What are the tire specs on your car?

And im sure the tire shop youve gone to has looked but check the tires for tread seperation and/or "cupping" on the inside edge of the tire. Ive had both issues before since im lowered, and these will both cause a vibration.

Also a simple check would be to have the shop go back to square one, and put everything back to where it was before they ever touched it, and work from there.

 

Big Al, what's up bro? Like sto4louis said, maybe they we're rotated wrong. Are your wheels staggered?

 

When I get my tires rotated, they usually dis-mount the tires, flip the tires around(because they are directional), then re-mount the tire, then switch the rims from Front (D) --> Front (P). Same with the back.. The front tires do not go to the back wheels.. They wont fit..

Tomorrow I should have some time, so I can take it back to the shop and have them Road Force Balance my wheels, and make sure that the tires are facing the correct direction..

The vibration has calmed down abunch since they put on the hub rings, but it is still noticeable. Should I have them put hub rings on the rear?

 

doh you dont have them on each wheel-! who sold you these rims anyway!
and the tire shop didnt notice this or only sold you 2- go find a new place to dwell

the purpose of the ring is to center then rim to the hub as the lug nuts are installed
Its possible to tighten the wheel with it slightly out of position and result in major vibrations

For what you must spend moving tires around- why even bother?
a fwd car wears out the fronts first- so you buy 2
then it wears out the rears- and the best tires always go on the back- so its new rears!

Plus with high performance tires there is about 100 miles where the belts in the tire get used to running a new direction- this can result in vibrations too

 

make sure they are hand tightening the wheels to 80 foot pounds- not a torque stick or air gun blast- then check it by making the torque guage click- that only means its at least that tight- have to bring it up by hand to do it right
overtight is a bad thing
