rear wheel wobble I had a guy pull up next to me at a stop light & inform me I had a rear wheel wobbling. The Wife & I noticed nothing while driving the car. So I pulled into the closest parking lot & had the Wife drive it slowly while I watched from the rear. Sure enough, there was a slight wobble on the rt. rear wheel. Went straight home & checked all lug nuts. That didn't help. I jacked the car up and swapped rear wheels to see if it was the wheel or possibly a bent axle or hub. It wobbled on the left rear side as it did on the rt. rear side. There is no noticeable unusual tire wear on the rubber. Oh I forgot to mention it's a 29 w/21" wheels. I've asked a couple of local Model A guys about it and basically they told me not to worry too much about it if there is no noticeable wobble in the car while driving or any unusual tire wear.
What are your thoughts? Now that I know about it, it's driving me nuts. There is a fellow close to me that has a wheel straightener, but I'm curious what everyone on the Barn thinks. Thanks, Smitty |

Re: rear wheel wobble If further convincing is desired ..... and/or .... if you would want to verify & report back with wobble amount?
1. Jack up wheel; place a "fixed" wood block(s) adjacent to circumference of the metal rim & rotate wheel. 2. While rotating the wheel, verify "exactly" the distance from where the wheel is farthest out-bound & farthest in bound. 3. If curious, you can try all four (4) while at it. 4. Usually 1/8" max in & out is recommended ..... many 86+ year old Model A wheels exceed this amount ........ & many Model A owners don't care & never care to verify. 5. If tested, you will be unique!

Re: rear wheel wobble Straighten, replace or use the spare...
I wouldnt want to drive it either with a noticeable wobble.. |
Re: rear wheel wobble Smitty,
Could it possibly be an AR wheel, on a later HUB/DRUM? I "think" lots of cracked centers are caused by AR wheels on the later drums. I have 5, ready to go, AR WHEELS/TIRES/HUB CAPS, that I CAN'T use on Vermin! Bill Misfit |
Re: rear wheel wobble Hi Smitty,
I am with Bill. After quite a few poeple stopped to tell me about the wobble in a rear wheel, I found that I had one AR wheel. I now have the AR wheel as a spare untill I can find a replacement. Regards Chris Cape Town |
Re: rear wheel wobble I had the same issue. Ended up being a bent rim.

Re: rear wheel wobble common sense prevails, do not drive until it is fixed. Mine was a bent rim with 2 broken spokes. Wayne

Re: rear wheel wobble I find few 19 inch bent but several 21 inch wheels are a few mm out

Re: rear wheel wobble Check to see if your hub is loose on the axle. If you have stripped or boogered threads at the end of your axle, the hub can back off the taper and wobble while driving.
Just put a floor jack under the axle and lift the car so the wheel is just off the ground, then try to force the wheel to wiggle by moving it fore and aft without turning it. |
Re: rear wheel wobble Hi Smitty,
If you do have this AR wheel/wheel drum problem condition, you may want to contact these guys to see what they have to offer to remedy this possible problem: http://www.speedwaymotors.com/the-to...e-wheels/28813 Don't give up ... just hope you can be happy. |
Re: rear wheel wobble Just talking out loud here but could a wobbly wheel put the axle in unnatural forces and that can lead to the axle breaking? Kinda like "bending" it back and forth as the wheel pushes and pulls.

Re: rear wheel wobble If it wobbled on both sides I would replace the wheel with a straight one. Did your left wheel wobble when it was put on the right side?

Re: rear wheel wobble Before getting wheel straightened try this:
Remove wheel from the hub and turn wheel around, then look at back of the wheel at the part which contacts the Hub. This is the part that usually wears a ring in the paint on the hub. Sometimes when wheels are powder coated ... the PC melts and drips to the lowest spot. This glob of PC can be quite large and thick and WILL cause wheel to wobble unless removed so that wheel can seat up against the hub surface. I have several P Coated wheels right now with this problem ... My first thought was to use a razor blade to remove extra PC. I wonder if this might break the PC loose from the edge of the wheel and start it to peel. Maybe wait until it cures and then use a Dremel tool. |

Anyway, if you have matching wobbly wheels on each side the forces will cancel each other out and the ride will be smooth ... more wobbly wheels needed. |
Re: rear wheel wobble my drivers side rear wheel has been wobbling for over 35 years(21inch) don't feel it don't care,tire wears fine.
