Wheel spacers - Vibration after installing them

Hey guys!

I recently installed hubcentric wheel spacers (1.5") and noticed that the hub bore of the back wheels were bigger than the hub. So in other words, back wheels where being held and centered by lugs instead of the hub.

With a caliper, I measured the hub and hub bore, hub bore is 108mm and the stock hub is 106mm.

I bought a pack of hub centric rings (106-108) they fitted perfectly and filled the gap properly. Finished the installation, torqued everything to spec, and now I am getting a little worse vibration. Not terrible, but annoying enough.

Considering that it's been almost a year and a half since I bought this truck and I have never balanced and aligned it, I went ahead and did both alignment and road force balancing hopefully waiting to see if this would fix the issue.

It didn't...

I'm still getting the same annoying vibration when reaching speeds between 60mph and 80mph.

Any other ideas on how to address this issue?

Thank you all!

 

Shouldn't need the hubrings, especially with just 2mm difference. I'm guessing they're plastic (if yes, I had the same issue with plastic hubrings). Most wheels these days are meant to be lug-centric, so I'd recommend paying special care as you first hand tighten, then torque. Always go in an alternating star pattern.

 

Switch the spacers around. Put the front on the rear. See if the vibration follows the spacers.

 

Thank you, rings are aluminum, and yes I tried my best to gradually torque them in a star pattern.

 

Thanks! I'll try that and let you know if it worked!

 

What brand spacers did you buy?

 

That's a solid idea

@Porroquio -- just reread your post. So to clarify, the 108 centerbore is only on the back wheels?

 

I bought these from Amazon, they have pretty good reviews so I decided to try them..
They look and feel pretty solid, well made and good quality. Didn't wanna go with Spidertrax as they are pricey.

Yes, only in the back wheels!

 

I would do what Windigo suggested, if the vibration follows the spacer, I assume it will then get rid of them. That link says they are forged steel and have a 106mm bore. When buying stuff like wheel spacers I would never cheap out. There is a reason most people go with bora and spidertrax.

 

they are fine if you buy a well known good spacer. I have hit stuff hard enough in my truck that I’ve bent my knuckle gussets. Have them on my samurai that I beat the hell out of and on every Jeep I’ve owned (4 jeeps) without a single issue, also installed probably 50-60 sets of them also without issue. The key is install, always red locktite the spacer to the hub, don’t buy cheap china spacers from eBay or Amazon.

 

Yes, I'll try Windigo's suggestion, if it doesn't work I'll return them and buy spydertrax or bora.

Is there any other brand that I should look into?

 

Spacer up font was 106mm and the rear was 108mm?
Any change in front to back rotation?
If so, get the 106mm wheel spacer.

Can you use your calipers to see if the bolt circle and center of hub coincide on the wheel spacer?

 

I would honestly just stick with those brands. It’s a pretty big deal as far as safety goes. You can get other on the cheap just not wheels spacers. I’ve seen my share of eBay spacers break or rip off on the trail.

 

All these spacers have a center bore of 106mm..
Only the back wheels have a center bore of 108mm.

Wheel spacers fit perfectly in the truck bores, only the back wheels are not fitting properly in the spacers.

 

Gotcha...

Could be your wheel's bolt circle does not coincide with the wheel's hub center. The hub ring spacer might be affecting this as well.

I'm assuming aftermarket wheels with tapered lugs...
When you take the wheels off the rear, are there lug marks on the lug seats that 'bite' into one side of the lug seat?

No change in front to rear rotation? This will probably tell you the most...

I'd get the correct bore wheels for the rear or take the hub ring spacers off and have the rear wheels and tires lug-centrically balanced. Only problem with the latter is, you'll need to rebalance every rotation; but at least it would confirm or eliminate the possibility. If it's eliminated as a possibility, you'll have to get another (hubcentric) balance to start the troubleshooting process over.

Definitely check the torque on all the lugs holding both the spacer on and the wheel on. 83ft-lbs iirc. The stock tacoma wheels are HUB-centric, not lug centric. A 2mm bore diameter difference isn't much but it's not insignificant if the wheels are meant to be hubcentric.

When you take off the wheels do you see any scratches/scrubbing on the face of the spacers where the wheel contacts it?
When you take the spacers off do you see scratching/scrubbing on the rear face of the spacer, or on face of the hub that contacts the spacer?

 

The fact that the cb on the rear wheels is different than the front wheels is odd. Seems like a cut corner or overlooked detail, which leads me to think that something else could be off. If they were my wheels, then I'd contact the vendor/company.

 

Yeah, safety is overrated anyways.
