Ah, the SSEi brakes might be undersized. Mine on the GXP haven't warped, but they were warped when I bought the car with 46k. Here'* to hoping they last!

What part of New Lenox?

I checked the tie rods and if I pushed really hard 9 to 3 I could get them to move, but didn't really feel any play. Not sure if I'm looking for the same kind of play you get with a bad wheel bearing?

However, rechecking my right side front 12 to 6 suddenly shows play, and it also had 9 to 3 play. Not sure why it didn't show play the first time I checked it, bearing was just in the right place? But no matter, I'm going to order a bearing for the right front. I see a Timken on Amazon for $95.

Really hard at 9 and 3 was prolly just the slop in the rack..

12 and 6, definately time for a new bearing. One thing I have noticed when they start to get loose is when they are warm after driving around for a bit, they can be hard to get much play out of, when they cool down is when it can really be noticed.


Also, little trick for a loose bearing that isnt noisy one bit. Remove the axle nut, put it back on and torque to spec. Still loose, add 10ftlb more torque. Continue until either the play is gone and the bearing isnt noisy and still moves free, or until you have to add more than 40-50ftlb (dont wanna risk breaking the axle)

The bearing on my 06 Impala had slop and vibration while cruising and braking around 61K on it, I promply did the method above (I had to go an extra 50ftlb) and viola, car has 79K on it, bearing is still tight and no noise.

Continue until either the play is gone and the bearing isnt noisy and still moves free, or until you have to add more than 50-75ftlb (dont wanna risk breaking the axle) Heed the warning, it takes a certain feel and judgement on when not to add more torque in the risk of damaging something!!!

Yeah the GXP front brakes are 13" and the rears are 12" I believe. Wilwood Estates...you mean right behind the library/commons where there'* that pond and greek pillars and stuff? My wife and hang out there all the time, eating mcdonalds or some cake from Jewel. Haha, you've probably seen my Regal or my Bonneville parked facing the pond from the Maple street end if you ever drive by there.

I had replaced the left driver side about 9 months ago so the right side is probably now due.

Hopefully, the bearing replacement fixes the problem of shudder while braking. Otherwise I may still invest in a dial gauge to check the run out of the rotors.

Please come back and report what you find once you replace the bearing. If these really are warping on people, I'm going to have to stop recommending them.

That top wheel bearing bolt is a pain to get off. Anyone have any suggestions? I have the 13 MM socket connected to a swivel and it is very hard to get enough torque or a rubber mallet to break it loose.
