Im sure theres already a thread for this but Im new to the forum and figured Id ask anyhow lol Ive got a 97 grand prix gt and this morning my abs and trac off light came on and im curious as to why and what kind of money im looking at? and if it will effect my braking until i have it fixed. I dont know much about cars so yeah theres that haha thanks
 


Probably a wheel bearing or the wires/ connector for the ABS (beside wheel bearing) are corroded. Easy fix.
 
Your ABS may not work, and you're looking at about $110 or so for a replacement TIMKIN hub assembly. Don't use the cheap Autozone ones. Check Rock Auto for it. Jack up the front end and put your hands on each tire at 12 and 6 and rock it in and out. If you feel play in that tire then that's the hub I'd start with. Can be replaced with basic handtools and a breaker bar. You will need a large socket for the spindle nut.

I would check the harness first, and then go with the bearing replacement. Mine had this issue and wasn't found until I stuck a multmeter on it and discovered it wasn't getting a signal back to the EBCM.
 


thanks, im just worried about driving it for now because as of right now i dont have the money to replace anything probably for a few weeks, would i be alright going about 3 weeks without fixing it?
 
If it's just the wiring that's effed up you can drive that car till the wheels fall off.

(the wiring won't make the wheel fall off lol)
 
first off look to see whats wrong then determinate if its a hub or not.

jack the car up, one wheel at a time, leave the lugs tight. then grab the top and bottom of the tire, do a push pull with each hand. watch the rotor where it meets the caliper, if its moving you see it there.

just tested my d/s front today, its moving a lot now. it used to just have a 1/8 inch nudge in movement.

if the hubs feel tight, then take each tire off and unplug each hub, all 4, clean the plugs, di electrical grease them, work them off and on a few times. also check the wires to that plug, as they cant get damaged.

this is all free to look at and figure out what maybe wrong.

if all of this seems good, go have the cars scanned as you just wind up tossing money at it. dont know what year you got, but some newer cars will show a abs code on the free scanner at AZ. older cars need a shop to scan it, and they will charge you most of the time.

This.
 
now i started to get a grinding type noise near the brake pedal when coming to a stop. doesnt happen everytime but did hear it a few times. any ideas?
 
no brake pads left? look at the rotors, are they all grooved up?

or the hub has gone to crap real bad.

test the hubs yet?
 


was there a squealing before the grinding? if so, you just bought new brakes.

if the rotors are all messed up looking, stop driving it asap. one will look like its been metal on metal. aka not nice and smooth looking.
 
no i dont think i heard any squeal. It was like a grinding/rattling noise that you could hear and kind of feel in the pedal
