Our T has the kind of steering where the one rod is turned from the steering column on the driver side out to the front (I don't know the nick names of these parts yet).

You can't drive the car much over 50 mph as the front wobbles and shakes at that speed.

Front rims were check, new front tires were added.

What would be the common problem here, and what upgrades or replacement parts (rack maybe?) are available?

Thanks
