Deuce shakes at 40 mph+?

[supeman100]

Hey guys, I just bought a bobbed deuce. It has 46s and is in pretty decent shape. But when i hit around 40 or more miles per hour the whole front end of the truck starts to shake, almost like its bouncing. What do you think is causing this? I filled all the tires up to the correct PSI and didn't change anything.
Thanks!

aside from loose front end parts sounds like tire balance. tire balance will do strange things like shake at 40 and disappear at 50

I would have whoever you bought it from fix it! That is unless you added the wheels and tires.

Check your alignment, and ask around here about the liquid for balancing the tire. What you have is noted as the DEATH WOOBLE.

Sounds like tires out of balance. There are several products out there to help with large tire balancing. The liquid ones are the best in my opinion.

also check that your knuckles are as tight as they should be and check , tie rod ends, etc, and media blast your brake drums ,40-60 years of paint can give you one crazy of a wobble, you may also need to get the drums balanced, did all this on my deuce , drives like it's on glass,
