2003 Bonneville SLE vibration when braking
I've been ignoring this for a couple months now, but I realize I really need to get it fixed. I already replaced the left wheel hub, the right probably needs to be replaced but I don't think that is the cause of this issue. Had someone mention the tie rods, not sure how to check them or what the symptoms are.
My symptoms are when I slow down at speeds above 35ish, I get a bad vibration that makes the whole car shake. The brakes do not pulse and the rotors appears to be fine. When I turn the steering wheel while parked it makes a kind of crunching noise. It'* not the power steering pump, sounds like its coming from the steering rack.
Hoping someone can tell me what I need to check or will know exactly what the issue is.

to test tie rod ends, if you can see the tie rod ends through the wheel just have someone move the wheel back and forth with the weight of the car on it you should see no play. a crunch when turning is alot of times the ball joints.
the alignment is half the cost of the job these days so if i suspect either part, i will do all the ball joints, upper mounts, and tie rod ends just so i dont have to do the alignment twice, plus if one is wore out the others arent far behind

Jack the car up on the right side so the front right tire is in the air. Try to wriggle the tire side to side, and then up and down. If it moves side to side, but not up and down, replace the tie rod. If it moves side to side and up and down, replace the hub/bearing. It takes very little movement to detect a problem. If you want a frame of reference, jack the front end up so both tires are off the ground and compare the tire movement on the left tire to right tire.
Pull the tire off and look for any obvious problems, such as worn bushings or loose bolts. Check the steering rack like Dan suggested.
Vibration when slowing down is usually the sign of a warped rotor. It may look flat, but you need to check it with a run-out gage.
Do you hear any rubbing/grinding/howling/etc. noise from the front right wheel when making a hard left turn. If so, that is one sign of a bad bearing.
Warped rotor, bad bearing and worn tie rod end are high on my list of suspects.

There is no rubbing, grinding, or howling when slowing down, just the vibration. The left wheel had side to side and up and down wiggle, replaced the hub and now it is solid. The right wheel I believe just has side to side wiggle, I'll have to check it again. Seems that would point to needing to replace the tie rods. I'll probably do the hub anyways, but I've never replaced a tie rod so I will need some coaching. How hard of a job is it?
I've always heard that a warped rotor will cause the brake petal to pulse, I have no pulsing at all. I have heard of bad wheel hubs warping rotors though.

last time i was up there he wiggled the steering wheel and there was a clicking type sound around the rack. i thought of the rotors as well but on a 2000+ it'* usually the backs that get the warping. will have to take a closer looksy

tie rods are easy if ya need them. biggest thing is making sure the length stays the same so you don't need to spend another $80 on an alignment.
let me know and i'll shoot up
