alte797 Posted August 13, 2007 Report Share Posted August 13, 2007 Hi guys Im new here and proudly own a 99 Deville that requires the Rear Upper Control Arm Knuckle replacement (passenger side only) . Thanks to this forum Ive already found a place where they can be purchased cheaper ! (Brasingtons @$385 vs our local GM Toronto Dealer @ $985 ) Anyways as much as I've read here I still can't seem to find a clear procedure for replacement. I took a good look at it tonight, and as far as I can tell, the procedure would be : 1. Jack the car up and remove rear tire. Support the car on stands. 2. Disconnect sensor unit from center of knuckle assy. 3. Remove sensor wire bracket 4. Remove Brake Caliper + bracket unit (leave brake lines connected) and set aside in safe area. 5. Remove Brake Rotor 6. Place Hydraulic Jack under lower spring arm (just snug against spring arm - no tension on spring). 7. Unbolt Upper Control Arm bushing (where attached to knuckle) 8. Unbolt Rear Control Arm Bushing (where attached to knuckle) 9. Unbolt Lower Control Arm Bushing (where attached to knuckle) 10. Remove Knuckle assy 11. Press out wheel Bearing 12. Re-install reverse of above. Guys does this sound correct ? Will I have trouble removing the bearing, is it pressed in real tight ?? Thanks in advance, any help appreciated !

caddypete Posted August 14, 2007 Report Share Posted August 14, 2007 I did my 2000 eldo's about a year ago. The hardest part was disconecting the sensor unit from the knuckle, had to hit it a few times to get it to come out of the knuckle, the bearing must have been a non event because I can't remember that.

alte797 Posted August 15, 2007 Author Report Share Posted August 15, 2007 Caddypete + JIMDTS Thanks ! I really appreciate the help. I ordered the part from Brasington and should get it shortly by UPS. I think I can handle the repair. Looks like the major thing to be careful of is to support the coil spring during the repair. I'll get an alignment after the swap and I'll post my experiences for others. I like the car, my first Caddy (My daily driver is a Mustang) Thanks again guys !!

alte797 Posted August 21, 2007 Author Report Share Posted August 21, 2007 Guys heres an update, I ordered a Right Rear Knuckle from Brasingtons and it arrived from Florida to Toronto in 3 days ! Price was $384 plus tax + delivery / duty. The guys there are very helpful. The replacement was very simple, it followed the same procedure as laid out in the thread with the following lessons learned : 1. After removing the 4 bolts I found my bearing hub was "stuck" in the knuckle. Really stuck. The reason it sticks is rust and dirt collecting on the channel where the hub sits. The best way I found to remove it is to soak the seams in WD40. Using a heavy Chisel (use safety goggles) and hammer, hit the Bearing hub in the bottom corner (taking care not to hit the dust shield) and try to work it sideways so it breaks loose a bit. When you see the Bolt holes start to shift / move you will know you've broke it loose. At that point take the chisel and try and hit it on the seam line where it fits against the knuckle to split apart. I know this sounds wierd but if you have the parts in front of you, this will make sense. 2. Take care around the sensor on the back of the hub, I went crazy and whacked the plastic and put a crack in it but fixed it with expoy. 3. If you do bend the shield dont worry, it will bang back into shape and you can paint it to hide the hammer marks ! Total repair time = 2 hours + 1 hour wacking the bearing. The car drives great now, NO SWAY and NO RATTLE !!!! Like new !! (and I save about $1,000 BUCKS !!) Regards Rob Link to comment Share on other sites More sharing options...
