2001 grand Prix abs/TCS/power steering/cruise

All is related. Cruse control will not work when ABS light is on. So if you get the car scanned for ABS codes, this would save you some time in hunting down where the problem is. That may miles on the wheel bearings, its getting due. The hub/bearing assembly comes with a new wheel sensor on it. Now funny this question came up, I just worked on one the other day, same thing. But the wheel hub assembly had recently ben replaced. It ended up being corrosion in the wire leading up to the wheel sensor plugin. The wires looked good until I got further up the line. Did a patch job there and good to go.

achem...make sure your battery is up to snuff...and does not have corrosion (which happens immediately)~ on posts and clamps...be sure the secondary cable to the block is there and attached securely so that the 50 Amps is happy with your connection~ electronics to not GET OLD....or GET All used up...I can't use this radio all the transistors are empty...is something that will not be said...so what is the scrapper is the lack of Proper grounding....the semi-conductors will cook themselves without proper ground~ the ABC and TCS all need proper ground ....so be sure the frame is grounded too~

First of all...WOW...179k on the original bearings is something to be proud of! But it sounds like it's time for a new set. The Hub assembly that houses the bearing also houses the speed sensor and will trip the ABS/Trac light when it goes out. If you're inclined, it's a rather tedious job that can cause you some hang-ups, particularly if the old hub is siezed to the steering knuckle. Make sure you rent a slide hammer with yoke, a 36mm axle nut socket, and an axle pusher from an auto parts store. AND more importantly, do not put anything but Timken or SKF bearings on your car, unless you just really enjoy this job. I don't, and have found these brands are money well spent. I'm not a salesman for those brands, just speaking from experience. Another tip...the NAPA store brand hubs are SKF (not Napa Proforma)...about $140 per hub...I highly recommend. I also recommend checking the PS fluid as well...I know this isn't the easiest task on a 3800 but could also be contributing to your stiff steering. Good luck!

Thanks to all you folks for your advise. I suppose I should have changed those bearings when I did the CV shafts 14 months ago... Oh well, that's what I get for being a tight wad. Lesson learned...again. I suppose you have to have either time or money on your hands. Guess I will have to find time because I am not flush with money!
