Ruckstell axle question.

Post by bobt » Mon Dec 22, 2025 5:51 pm

I have a left rear wheel wobble on my 1926 Roadster. It has a Ruckstell AND Sure Stop disk brakes AND floating rear axles. Is the actual left rear axle a special one or is it a stock one? The only thing I've done is changed the wheel with another on and It's not a bent wheel. The wheels are powder coated large steel spokes. Thanks, bobt

the axle should be a stock axle. ruckstells used the same axle as a stock rear axle.
if you got a wobble it might be as simple as a loose axle nut. if it still wobbles it might be a bent axle shaft or a messed up hub

A lot of T's have wheels that wobble. It comes down to how bad the wobble is. So, how much wobble have you got?

I have Sure-Stops and floating axles with wires on two T's. No Wobble. Pull the wheel and see if the hub has run out. It may just be the wheel.

I'm thinking floating hubs don't wobble have you tried checking the wheels on the front?

I've had the car for about seven years and I drive a lot year round. Last week a gentleman behind me motioned for me to pull over and told me about the problem. Yes, I have a little wobble on the right rear but the left is probably 3/4". I plan on pulling the drum/disk off today. bobt

Yup, that's a bit too much...

OK. I checked this, that and the other. I'm pretty sure I have a bent left rear axle. You are correct in saying that the floating hub has NO wobble. The disk brake rotor has NO wobble but the hub (wheel adapter, cause I have spoked wheels) is where the wobble is NOW, How do I drop the rear end to replace the left side axle. I was told the it uses a stock axle even though it has a Ruckstell. My main concern is removing the rear spring . 1926 roadster. bobt

Whoa! If your rotor has no wobble, and your floating hub has no wobble, it suggests to me that your axle also has no wobble. The magic words, I believe, are "wheel adapter". Look to the adapter for your trouble, since that's where the problem seems to originate. Either the machining of the adapter itself, or its mounting, or ???

Are you using Model A wheels, or Model T wheels, adapted to wood wheel hubs?

Unless it has been hammered on at some time to dislodge a stubborn wheel, the axle has a centre drilling. You can visually check this by running the car while it is securely jacked up. If the centre runs truly your axle is not bent. The wheel/adaptor mix may well be the problem, especially if an original wooden spoke wheel provided the donor hub.
