Violent Vibration above 65 mph

Hi Everyone,

I hope someone else has had this problem and can help me...

Just had new tires mounted and balanced on my 2011 Santa Fe. I purchased Toyo Celsius tires. I purchased the tires on line and had Faulkner Hyundai in Harrisburg PA mount and balance them.

When I drove to work 2 days later, I found that the vehicle starts to vibrate above 65 mph. When I get to 80 mph (typical traffic speed on I83 in the morning), the vehicle vibrates so badly that I shake in my seat.

This shaking leads to a feeling of lack of control.

I'm hoping the dealer just screwed up balancing the wheels. Faulkner Hyundai uses a road force balancing machine.

My old near bald tires (the factory original Bridgestones) had a tiny vibration around 65 that went away as speed increased. With the new tires, the faster you go, the worse the shaking gets.

My 2011 Santa Fe still has under 30,000 miles on it!

Any ideas what could be wrong?

Thanks!

1 - Make sure ding dong did a "2 plane" balance

2 - What they use for ballast ?

3 - Steel,, or aluminum wheels ?

4 - Do RFV on tires, could be crappy tires as far as the belt overlap in the tire construction too

5 - Did they do balance down to minimum number, or balance to get by setting ?

The Santa Fe has aluminum wheels.

I don't know the answers to your other questions yet. I have another appointment at Faulkner Hyundai on Saturday.

I think the technician that worked on my vehicle was an idiot though...

I also requested 3 new wiper blades. I had to go back to Faulkner after work on Monday, as the technician put all the wrong blades on my vehicle. The service experience was hortible. Don't know if I'll ever go back there again.

Thanks for your reply.

Give original shop one more chance. If fail, then have balance re-done on Hunter 9700 (bound to be a shop somewhere nearby that owns one). You can find a shop that has one at this site >> GSP9700 Locator. There are 10 such shops within 5 miles of the 17101 zip code. These machines aren't a panacea, but when kept calibrated, and in the hands of a decent tech, they'll point out issues that others will miss.

Make sure whoever does the job uses the hub attachment and not the spindle. Your wheels are 'hub centric'.

Get before (BOTH with the weights as installed by the first shop, and the raw tire/wheel sets) and 'after' numbers. If it resolves your problem, take the bill back to the original shop.

Why dealers employ people representing them that don't do the job properly is unbelievable. (where is the shop foreman?) I affects and reflects on them as well as other mechanic. Owners won't come back

Where has attention to detail gone. More and more I find as a consumer I know more than what the guy in the business does. It take 10 times longer to fix the screw ups than it would have doing it right in the first place. They can't charge you for their screw up. Some might trying pointing something else claiming it need replacing before doing it all over again to get more money out of you. LOL

I found this out first hand when I managed an oil sampling lab for a local Caterpillar dealer. The mechanics would bring me samples into the lab that they thought were coolant. They were not - hey were diesel fuel. I had to go out to the shop and show them where the radiator was - SERIOUSLY!

From what you say I would find a new dealer. I found out a long time ago that you cannot argue an idiot or indifferent service provider into competence. When I was a kid I took tires in to be balanced and noticed that his indicator was broken. I asked him how he could possibly balance a tire like that and he said he did it by "feel" . They are out there.

Exactly. I guess he thought I wasn't watching or would't know the difference. It was a long time ago and I don't think I paid for it. It was a balancer that had a shaft charged with high voltage just below the point of discharging to an outer conductor. Any inbalance in the tire caused a spark discharge from the shaft to the conductor corresponding to the heavy spot on the tire. The gap read out was caked with dirt and obviously has not thrown a spark in years. Anybody ever seen one of these antiques ?

Represents 2 plane for wheel with clip-on weight use

Represents 2 plane for most aluminum, I think this is best way if not using clip-on weight at inner bead
Image



Turn that joker down to balance down to 5 gram (slight less than 1/4oz)
Image



Set to measure RFV (road slap of belt overlay in tire tread.. MICHELINS common for very low RFV numbers

I had a quick comparison via CTC website. Close to twice the price for the LTX tires. Not that I like even the looks of the Kumho Solus. Maybe ok in California etc but here we need tires that still work in foul weather and for me millage rating is nothing. It traction thats the key rating without it they'll still be on the vehicle when it goes to the wreckers.

I am not looking for any at this time. My old tires still have plenty of thread as do my winter tires. If I did anything since I have OEM rims for both sets. I'd run the Winter tires as summers wearing them out and get a newer set of winter rubber. Winter is where its more important when the rubber meets the road. Also I could dump summer and put the new winters in there place.

I had a similar problem on a SAAB I once had. It turned out to be a bent rim. The tire balanced perfectly, and was not noticeable on the back with the old tires, but when that rim was on the front with new tires it was bad and the distortion became evident at speed. It was spin balanced only. Fortunately a new 'refurbished' rim from a place in Bath, PA fixed it.


Good luck.

Print my post on how to use the machine, then stand there and have ding dong set the machine according to my pics while you watch..

PROBLEM SOLVED

It was indeed incorrect wheel balancing.

I was at Faulkner Hyundai earlier this morning. This time around I got a really good service advisor - James, who actually cared. James said he would get me someone really knowledgeable this time to rebalance my wheels.

I had a technician named Blake. Blake found that both my rear wheels were balanced incorrectly. They were off by 350 on each side. I'm not sure if that is grams or what, but he balanced the Santa Fe correctly this time.

Blake took pictures of the Hunter Road Force Balance Instrument screen this time with his smartphone to show me each step of the way what the incorrect and correct settings were.

We went for a road test after he balanced the wheels and the Santa Fe rides like it's on a monorail now. Smooth as glass.

I was fearing the worst - but as most of you said, it was a balance issue.

Thanks for all the input. I really appreciate it.

We have printer on ours.. Put wheel straight from car on spindle, spin, see error, then correct the balance,, save to info, do next wheel, save, and so forth, then print screen to reflect all 4 wheel initial error, and final.. staple to ticket to document work done and balanced per machine' logic

Tripplec,
I know this is off topic for this thread, but I second the vote for the Michelin Premier LTX. I ended up paying $1,145 for those at Costco, but it was money well spent when compared to the Pirelli tires that I removed. The Michelin tire had a way better ride - vehicle tracks straighter, does not wander around in the deep ruts, and absorbs the small bumps a lot better. And when accelerating a little quickly from a stop with the front wheels turned there is no spinning the front tires. I would really have to nail it to get the front tires to spin. With the Pirelli's I had to be very gentle when taking off on a turn in order to avoid spinning them. I think the Pirelli tires were just very hard and therefore had a terrible ride and never gripped well.
Can't speak to snow traction, as I just pulled the Michelin tires off last week to put on my dedicated Firestone snow tires.
Scott.

Great news!

Now you need a sign on the back that says DO NOT TAILGATE. I have a bumper sticker from Geno's Garage that says "I may be slow, but I'm in front of you".

Most of the eastern PA drivers are rude and pushy. They commute through here every day. If they're not doing 90, they're weaving, tail gating or cussing you out. I have a big stinger in the hitch on my truck. I just love dragging the brake so those really bright nuclear red tail lights blind them. It really tics them off. Our Tucson is getting a set of red blinders too

Yeah, I hate to admit it, but PA drivers are some of the rudest out there on the road. On 83 in the morning and afternoon commute to and from work, I get to witness all kinds of idiots!

On the very steep hills on 83 there are 3 lanes. The right lane being for trucks who can't make it up the hills with any sort of speed - so as not to hold up traffic. Idiot drivers weave through all three lanes just to gain 1 or 2 car lengths. STUPID!

Back on topic, these Toyo Celsius tires are really grippy - we shall see how they perform in the snow. ALL the reviews that I read said that they are as quiet as all season radials. They are not! They are not as loud as a pure snow tire, but they are not as quiet as an all season radial. They sound similar to a pure snow tire only a few decibels less.

Consumer Reports rated them number 1 along with Nokian all weather tires. They tested both on a hockey rink and were impressed with the traction on ice. Can you really believe people who test toasters though???

I know. I really hope they train their personnel better in the future!

Unfortunately today, businesses feel that they can hire someone off the street and have them cookbook through a critical procedure!

I'm still at a loss as to what was meant by each rear wheel was off by 350. What is 350? I asked the technician who thought it was ounces...

That would be impossible as it would be almost 22 pounds.

Is the 350 a measure of mass? 350 grams??? Weights???

The Hunter unit is capable of recording some very interesting vibration statistics -- which is nice, because that's what the customer typically feels in the butt as well. The amplitude and nature of the harmonic and TIR numbers can tell a really savvy tech a good bit about what's going on and likely sources for issues. DEFINITELY takes some experience to properly interpret those, though. They don't just explain themselves. If I can, I'll take a snippet of the 9700 manual's "Theory of Operation" that might be of interest in that it describes a couple of the things being measured.
