1930 Model A

[DR]

Hello,

Can anyone give me some ideas on what would cause the front end to shake after going over a manhole cover or a bump in the road. I basically have to stop the car and then proceed from there. I checked the king pins by jacking the car up and they wheel seems like it has no play. So I am not sure if this was a common thing for these cars or not. I am still learning about it. Please advise.
