When I purchased my coach the last owner supplied a set of spacers, Said he took them off because they caused a front end vibration, After some thought and new front end bearings last spring, I reinstalled them again and still a vibration, Could they be out of round? I have them off the unit but really liked the way they took away the wonder, Anyone else run into this?

I do not see any hub centering rings on your spacers. It is very hard to center a hub centered wheel... and keep it centered without the centering feature.

The spacers look to be designed for lug centered wheels. (And of course matching lug nuts.)

JimK's spacer (and your spacer) have coned lug nuts to center the SPACER onto the hub. JimK's spacer has a lip that centers the pilot hole of the wheel onto the spacer... just like the GMC hub does. Your's does not have this lip.

If you use oem style wheels (or hub centered Alcoas) with your spacers, your spacers do not have either method to center the wheel. (Hub or lug.) SO... you will have problems getting and keeping the wheels centered... causing vibration when going down the road.

You could use lug centered front wheels if you want to use these spacers. (Maybe Eagles from Jim K.)

AH I wonder where these spacers came from I can see the difference with the Applied GMC ones, Maybe just best to buy Jim K,s spacers and be done with it, Now how the hell do I get rid of mine, Can't sell them to the community with this knowledge.
I really just need to hold out for the Hubler Front end.
(now can someone sell this to my wife?)DAN GREGG?
I,ve sold her on three GMC,s so far and 31 plus racebikes and equipment for our race series but the buck has stopped!....

Looking at your pictures I would think that it would not take much to turn a couple of sleeves on a lathe to inset into them center of those extenders. You could make them out of steel or aluminum. The centering ring does not hold the weight of the coach. It only holds the wheel centered while you are tightening the lug nuts. You could leave the sleeves installed or or cut them a couple of thousands under size and remove them after you tighten the wheel.

I have often wondered if centering rings would not be a good idea. On my son's car, the hub's centering ridge does corrode and make it very difficult to remove his snow tires (mounted on steel rims) in the spring.

I wonder how "tight" the fit of these rings should be, as corrosion can always be a factor. Are the hub-centered Eagles a very tight fit or is there some wiggle room built into their specs?

"Thanks guys"
I see it know, I have contacted the machinist for our club and looks like a removable one can be made up so my alcoa's can be centered on the hubs.I hate to loose the spacers and looks to be a easy fix.

I have just took all my rims into work and repolished all of them, Hours of work there, In fact my last one will be done tonight (what a difference)

George,

When he next mounts his tires suggest he paint the mating surfaces with anti-sieze. It should prevent the corrosion joint problem. I use it on the back of my Alcoas.

Jay,
The fact that all our spacers are hub centered.
Because the lug nuts have a taper is no reason to arrive to that conclusion.
When we worked with the whel spacer manufacture, they felt that that
nut would work best to compress the spacer to the spacer.

Jim I not sure my spacers came from you at least they look different in the pictures, Mine do not have the centering lip to center the rim to the spacer, Maybe early design, Im not sure as I said they came in a box with the coach and with the same concern with vibration.
I will however send them down on trade on a new set from your great store? Rolling Eyes I do have an overdue new front hub and old used Knuckle that has to go back to you,

Jay,
We can check it out and if possible, we will machine a adapter to center it .

There is no need to make centering rings or anything. Trade (or sell them) to someone who runs a lug centered wheel, like the Eagles or something. As long as they KNOW what they are getting...

They will also work with JimK's hub centered Eagles as they still use the lug centered lug nuts.

Maybe the spacers were machined off center.

I might be interested in them if you do decide to buy spacers for hub centered wheels. I am running true lug centered wheels that use 60* conical seats, I've had no issues with 1500 miles sofar. Eagles Nd alcoas use the schank style nuts which make lug centering more difficult. So for me to run such spacers wouldn't be an issue...
