Re: 1998 gmc jimmy
The shimmy is mostly likely being caused by one of two things either your alignment is out or one of your tires is bubbling or warped take it to Les Schwab and ask them to check it. I had the same probelm years ago when I had my Civic, for example I had driven on snow chains on bare ground for one too many miles and caused channels to form in the shape of my chains on the tire which caused a biggggggg shimmy. Live and learn I was only 16.

calipers sticking ,,, brakes shake because the rotors warp from the heat, also check your wheel bearings as they are problematic in these gm trucks ,, price of wheel bearings are way cheaper online rather than any parts store
Need more info...front end you say... A particular side? Is replaced tire the same as other 3 tires? hear it while driving, or braking, or both? Hear it more steering left or right or going around a corner?
Could be a front wheel/hub bearing is my only guess at this point. Howling or groaning could also mindicate a transmission problem.
FRONT END SHIMMY AND SHAKING COULD HAVE A TIRE OUT OF BALANCELOOSE OR WORN WHEEL BEARINGS, WORN OUT BALL JOINTS,WORN OUT TIE ROD ENDS, FRONT END NEED ALIGNMENT.BRAKE ROTOR WORN OUT OR WARPED, MANY THINGS WILL CAUSE FRONT END TO SHAKE SHIMMY.
will try to help. when front wheels shake while applying brakes and you can feel shake in steering wheel, front brakes and rotors need replacement.rotors are warped,if you replace front brake pads, it will return[shaking when you apply brakes] suggest that you replace front rotors[both] replace [both]front brake pads. cost? i would charge [brake pads cost $55.00] labor,$60.00] total $115.00 thank you for choosing fixya.com
This could be caused by worn front end parts, and or unbalanced tires. to test with engine off the key in the ignition switch turned to the run position turn the wheel back and forth not enough to move the tires, if the steering wheel moves more than 2 inches then you have a problem and I can tel you how to test the front end parts to determine how to fix. If it's worse with the brakes applied then it is just amplifying the problem.
It sounds like either warped rotors or grease/oil on the pads. Jack up the front and pull the wheels off. Turn the rotors by hand to see if the rotors turn freely, then drag, then turn freely. If there is no grease or oil on the rotor surfaces, you need to either turn or replace the rotors. The job is a royal pain in the ****, so you may want to take it to a reputable shop.
