Three out of 4 king pin races cracked as shown. Too much preload or just faulty bearings?

Hey guys, I'm trying to correct the Jimny Shimmy and some research has lead me to question the method our wheel balancing is being done. How does your tyre guy balance your wheels? Do they just mount the original mags with the cones on the machine? I've since found out there's different ways wheels are centered on your hubs and they should be mounted to the balancer the same way. Jimny's have lug or stud centered rims so the cone mounting won't balance your wheels to the correct center. I had the last balancer say my rims are all buckled, proof that they are mounted to the machine wrong? I'm going to phone some other tyre shops to find a place that uses the stud adaptor for lug centric rims, hopefully that is a major part of our problem. Brad Sent from my iPhone using Tapatalk |

Absolutely nothing wrong with the cone mounting system if set properly. It is possible to mount a wheel out of whack if you're in a hurry, or there's some shit on the faces, but in general they're fine. To set a machine for fixing by the wheel studs would send the cost of balancing to $100 per wheel, as you'd virtually need to either have a machine for each stud pattern and size, or spend an hour or two setting up the machine for each hub. When mag wheels are machined, the centre and the mounting faces for the tyre end up being synchonised with each other, therefore a cone wedged into the centre can only ever result in the rim running true, unless it's been damaged in some way. The likelihood of ALL rims on one vehicle being buckled is so remote as to suggest this bloke doesn't know how to use the machine and you should go elsewhere and try again. |

You can get king pin shims to add more load to the bearing that corrects the factory wobble or at least remove the factory pin spacers. |

On car balancing is the best when you run into a temperamental front end like the Jimny,hard to find in Aust. but they are around particulary with the Truck Wheel align centres. https://www.youtube.com/watch?v=7UP97bO-MpU |

Well now you know why it was wobbling. |

Jimny's have lug or stud centered rims so the cone mounting won't balance your wheels to the correct center. Just my $0.02 - yes - there are lug centric rims and hub centric rims, and yes, most Suzuki rims are lug centric, but, if the center bore on your lug centric rim isn't concentric with the rim, then there is something seriously wrong with your rims. The lug centric/hub centric issue is actually one of how the rims bolt to the vehicle, and you'll find that some vehicles can have either type from the factory - one of the Mitsubishis in my driveway comes with lug centric steel rims (most steel rims are lug centric), but if you take the factory alloy option, those are hub centric.

Are you suggesting that the balancer's cone adapter is the cause of the rims buckling? Quote: I'm going to phone some other tyre shops to find a place that uses the stud adaptor for lug centric rims, hopefully that is a major part of our problem. Good luck - both on finding a shop that uses a stud adaptor - and with eliminating the Jimny Shimny by balancing - I'll just say that I seriously doubt that wheel balance is not the issue. |

Sounds like your rims are buckled causing all sorts of issues. Sent from my iPhone using Tapatalk |

When they first tried mounting a wheel on the machine they had trouble getting it mounted with the cones. Then once it was on they said the rims aren't true. So I assumed that the way they mounted it was probably to blame not fully the rims. Sent from my iPhone using Tapatalk |

Yeah id say those king pin races are the culprit or a bent front diff. Swap em for new ones and i reckon will be fine |

If you’re still keen on chasing the balancing thing, you’ll want to ask if they have a high speed machine. I know some BobJane places have them, there’s sure to be heaps of others. BobJane where charging about $20 per tyre for the superduper balance about 5 years ago. |

Sent from my iPhone using Tapatalk Not having witnessed it I can't/won't agree or disagree - a buckled rim can causing mounting issues and an improperly mounting rim can show up as out of true - but an experienced operator should be able to tell the difference. |

 Wheels balanced and aligned. Drives like a new one with no shimmy at any speed up to 100km lol. Sorted for now. Sent from my iPhone using Tapatalk |
