Have 2004 dodge ram1500. have a wicked shimmy at slow speeds, feels like tires r going to fall off. shaking is still there at higher speeds. tire pressure is good all the way around. truck drifts to t

sounds like a bad tire or tires out of balance

great danger there. dont go fast.
can be tires out of balance (tire weighs feel off)
or wheel falling off (ever check the lugs)
tire bad. (bulged, delaminations , man killer tires, like Firestones)
tire rods balls, ready to fall off (more man killers)
ball joint ,ready to fail. and far far worse...
why not get the car serviced, have them check it out before.... bad happens.
noise and vibration or shaking on any machine means , doom is coming. in most cases,.

Have your tires checked for tread separation and your wheels checked for balance. Out of balance tires will go through harmonics such that at one speed it will vibrate a lot more than at another (higher or lower) speed.

check your ball joints . jack up the front end and grab the front tire push it in an out if the tire moves in an out your ball joints need replaced .do this to each tire ,if they go all the way out this is an expensive fix ,catch it before it does

Check your ball joints. also, if the tires are somewhat worn many times they won't have enough rotating mass to overcome side harmonics and can shake but most oftern the joints are worn. No play is acceptable there.

check the cv joints on both drive shafts. i had a dodge van that did the same, felt as though the front left tire was about to fall off, but turned out to be the cv joint at the tranny on the left shaft.

Hello. Most likely you have an out of balance or out of round tire. A simple way to check tire balance - if the shimmy is present at one speed and not present at another speed, then you most likely have a tire out of balance [sometimes the tire balancing weight[s] can fall off. An out of round tire or bent rim usually shimmies at all speeds and replacement of the tire or the wheel is the only fix.
Begin by driving to a reputable tire store and have them check your tires, a free service in most instances. IF it is not a tire, it could be that you need a front end aligmnent.

PS please rate my answer. Thank you and happy holidays.

Usually if u can drive into and out of a shimmy it is tire problems, usually balance. It can happen at diffenent speeds. The "shimmy" is the tires bouncing.

did you ever let somebody check the wheel allignment, it may be the camber shaft.

U have a seperated cord in the body of tire, this is very dangerous, have a tire shop look at this ASAP
