my 91 lincoln town car shakes when driving over 45 and squeaks whenever im turning from a dead stop is this a huge problem? or a some what easy fix?

okay...have your tires balanced....better still measure the amount of tread left with a penny...you should be able to bury the top of lincoln's head 3/32 of an inch...plumb worn....get new tires or have them balanced at a shop that does dynamic balancing~~~next problem, squeaks...when turning? you may need some ball joints, especially if it tends to wander about the road...will call up and price them if you can shimmy under there and inspect them with a large channel locks....squish them together and note the amount of play~ could be a simple component belt...YOUR power steering belt is LOOSE~....and needs to be changed...probably along with the tensioner and idler pulley~

A bit more detail, the shaking is real light at about 45 to 60 and gets a bit worse at higher speeds. Also the shaking stops whenever I let off the gas pedal. And like i said the squeaking only happens when I'm turning from a dead stop, like at a stop sign or light. i had two new tires put on and all my tires balanced and rotated about 4 to 6 months ago. The tire shop said that the other two tires were okay for a little bit longer. Hope this helps!

you driving in a somewhat muddy environment, 'cause this would play hell with your newly balanced configuration~

"The shaking stops when I let off the gas pedal"... 1991 Lincoln TC is rear wheel drive, check U joints in driveshaft...may have two different issues here
