Does this sound right?

[TnBronc14]

2023 Obx non sas. I have had many different vehicles that I have put different sized tires on, but none I have ever done any suspension work to. After doing this I wish I would have not gone down this path with the Bronco either, because it has been nothing short of disaster. Had a shop do the rough country coils, dirty life 17 inch rims and 315/70/17 BFG's. Shop has been through 2 sets of BFG's. Now switched to Nitto recons in the same size..still shakes. Now the shop is saying they ordered hub symmetrical rings for the wheels. Does anyone think this will fix the problem? Tried to do a little reading on what they do, and sounds like it may help, but at this point I am open to any suggestions.

They mean Hub Centric Rings... they won't help, Bronco's, like most vehicles these days, Use lug centric wheels, meaning they're centered by the cones of the lug nuts, not by the center bore of the rim...

I'd suspect a poor installation on the lift kit, or a grossly out of balance rim, first thing I'd try is having the wheels balanced by a different shop to see what they say..

Hard to say. I doubt tires are your problem. It's either a bad lift install or bad aftermarket wheels.

Have the wheel and tire assemblies been RoadForce (Hunter Engineering) balanced to eliminate the wheels for runout or out of round including tires?

Hub centric wheels will help if that's all it is but if the wheels or tires are still messed up it might change the shake but won't cure the problem of a bad wheel or tire.

The best way to diagnose is to use a vibration analyzer to find out the frequency, G and order of the vibration. Meaning, is the vibration engine rotation speed, driveshaft speed, wheel/tire speed, etc. The leads would be placed on a non rotation part then driven to see what corner of the vehicle has the highest vibration and order (how many disruptions per revolution) to narrow down the issue.

How many inches is your lift? What speed does the vibration or shake start? What does it sound like? Does it go away at a certain speed?

Most likely suspect is going to be wheel(s) or tire(s) but it sounds like they might have ruled out tires. Road Force is the absolute best way to figure these out if you suspect a tire or wheel.

When mounting tires here we have rotated the tire 180 degrees to aid in balancing. A colored dot on sidewall indicates where the valve stem should be. If the tire does not want to balance out then try moving the tire 180 degrees and rebalance.

Could be a bad tire, bad wheel or even the balance. Are they using balance beads or stick on/ pound on weights???? Like Flip just said above. RoadForce will tell you alot about the combo.

I think I need to have them road forced balance, because this is the third set of tires, and now second brand of tires with the same result. 2 inch lift, shake starts as low as 35mph and just gets progressively worse to where it feels like something might come apart on the highway 72-80mph.

Do you know if they used balance beads or the conventional pound/stick on weights???

they are using the stick on weights

 

[BAUS67]

they are using the stick on weights

Ok I asked because in some cases the balance beads can act like you are describing. Stick on weights is a good thing.

Bronco and Ford Ranger DO use Hubcentric wheels. Hubcentric spacers are recommended if

Bronco does indeed have Hubcentric wheels as does the ford ranger.

I can't find anything specific saying that the Ranger/Bronco Require a hub centric wheel, and they call for an acorn bulge style lug nut. If you use an acorn style lug nut, it is going to center the wheel, regardless of the bore. So, If have a hub centric wheel, and your lugs or rim are not machined and cast perfectly, your lug nuts are not going to seat and tighten properly. It's a function of the wheel, not the vehicle.

The factory wheels could well be controlled and qc'd to meet those specs, But his Dirty Life wheels are manufactured in Asia, and if he buys hub centric rings those would likely be asian manufactured as well, so QC on those is not likely going to be up to Ford's standards.

I stand by my original statement, hub centric rings are not going to fix his problem if everything else was done correctly. They may actually exacerbate the problem if he's got a poorly manufactured rim.

Seems to me like a balance issue. Could be a defective wheel or tire. And it could be hub centric issue as well. It could also be very bad alignment- how does the vehicle track? Not all shops are good at balancing or at installing lifts. I think most vehicles with factory wheels are hub centric. Some aftermarket wheels are not hub centric. I try to stick with hub centric whenever I go with aftermarket wheels if possible to avoid balance issues. I have gone non hub centric at least once and I did have balance issues.

Try putting the factory wheels and tires back on. That will either confirm or eliminate that the new wheels & tires are good or bad. With the factory wheels and tires if it still shakes, you have an issue with the lift components or the install. Generally speaking, the Rough Country brand is cheap Chinese crap. Start by reinstalling the factory wheels and tires.

Thank you for the info
