Wheel Balancing problem - Even after silver / Gold on Car Balance on New Kakadu

[Bawky Member Find all posts View Profile Close Bawky]

Hi,

I am hoping someone can shed some light on this problem...

We purchased a brand new Kakadu and drove the car straight to BJ, changed the tyres for Yokahama Geolandar GO12's with a silver balance, meaning rim and tyre are match mounted so that the heavy part of the tyre is mounted 180 degrees to the heavy part of the rim. Then only a small amount of weight correction is required.

This resulted in viabrations on the freeway. These were felt through the seats, doors and small amount through the steering weel, at 100km/h and above.

They since checked twice with a roadforce machine which applies 500kg pressure on tyre whilst the tyre and rim is spun. They re-did some work on the balance, completed on car front balance after checking match mounting. After a test drive showed the problem, they swapped front to rear. Hours of waiting around and test driving.

Problem still there, more pronounced in the steering wheel viabration. The steering wheel moves clockwise, anticlockwise, back and forth when you don't hold it. When holding the steering wheel the steering wheel seems only a little bad. Hold the steering wheel in your finger tips and you can see the movement. The car shake is felt at 100km/hr and worse at 110 and 120 km/hr.

I have the same tyre type on my SR5 and no problem. Does anyone have any suggestions? I am thinking of asking for a refund and asking for my OEM tyres to be refitted. Sad I know, but I want a smooth ride.

Wish I could tell you what the problem is Bawky. I have an 09 Kakadu which had BFG's on it at time of purchase and now has Bridgestone D697s (Vicroads compliance issue being the only reason for swapping). I've never noticed an undue amount of vibration with either but I did notice a lot of balance weights on the rims after the D697s were fitted. The ride is smoother with the D697s but I'm not entirely happy with the rate they seem to be wearing at, still investigating there.

I can't tell you if the oem tyres were any different as I never had them, they were swapped out by the previous owner prior to us purchasing the car from a dealer.

Can you see where the red and yellow dot on the tyres are in relation to the valves?

Sounds like steering wheel wobble? Rather than vibration.
More to do with out of round wheels and or tyres.

If the first issue was through the seat then is more than likely coming from the back wheels, if the issue is now at front then it sounds like it is something to do with those front wheels that were on the back. Get the wheels checked for out of roundness.

I will ask them to check the roundness of the tyres. Thank you for the tip.

Red and Yellow dot relative position to the tyre valves

Hi amts, the photos below show the relationship of the red and yellow dots to the valve. BJ told me that the red generally is to line up with the valve, however they said they determine the best location during the match mounting process.

I was talking about the rim as well.

I agree with ####, sounds like run out issues on the rims or tyres.

Hmm, it's normally yellow to the valve stem and red to the mark on the rim showing the low point dimple/notch (usually for steelies). For alloys, the yellow dot should correspond to the valve stem. I could be wrong here but I'm no tyre fitter.

I also noticed that all (except for one where I can't see the weights) the weights are near the yellow dot. I think if BJ rotated the tyre with the yellow dot next to the valve stem, they would end up with a tyre that is easier to balance with less weights needed. This doesn't cure the out of round tyre issue, though.

Thank you everyone for your posts, they are really appreciated.

amts, the rear drivers wheel appears to have no weights on it, unless I am blind. I will check that out with BJ.

Regarding the run out test on the rim and tyres, how is that performed? Is it an easy test? I wonder if the roadforce machine would be testing for that automatically? I have to drive 2 hours on a freeway on Saturday morning, I sure hope this can be fixed sooner.

These work really good,, I have put 4oz in each tyre.. http://www.ebay.com.au/itm/390603237...84.m1438.l2649
The tyre shop tried Equal powder first but that was no much good.

Yokohama was one of my preferred brand of tyres when i owned my tyre store , as i never had a problem with them, out of roundness was never as issue (same as Toyo)
and just re balancing the wheels over and over wont achieve anything , i would be seriously looking at the method they are actually using to do the balance , how is the wheel mounted onto the balancer , with fingers or cones?
Also you said the vibrations are on the freeway? , i am not sure what the roads are like over there but in Perth , every 4x4 i have owned vibrates on the Freeway as they are not graded smooth enough for modern vehicles
