I'm almost posistive that's standard procedure for the TSB, they're supposed to clean the rotor and surfaces on the rim first, torque to 140ft/lbs and see if it goes away. Replacing $5,000 sets of rims everytime somone comes in with wheels that are not torqued properly would be outrageous.

Even with replacement wheels, they still click.

Did the TSB 39,000 miles ago and the clicking hasn't returned. The lug nut torque value is 158 not 140; don't believe it's being universally followed and could be the reason the clicking returns for some.

The users manual says 140ft/lbs. I torqued mine to 140 with no load on the rims and have not had any clicking noise. Has it changed via some TSB since then?

Correct, the TSB changed that value a few years ago, but I had to show it to my service advisor and he passed it on to the techs. You would think that the manual for the 2010 and later models would reflect the change.

PIC5136B: Clicking Noise From Front Wheels - (Jun 2, 2010)
Subject: Clicking Noise From Front Wheels
Models: 2009 - 2010 Cadillac CTS-V
--------------------------------------------------------------------------------
This PI was superseded to update wheel part numbers. Please discard PIC5136A.
--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
A customer may comment on a clicking noise emanating from the front wheels. This condition is noticed at low speed (walking speed) during full wheel lock turns on dry clean pavement (Full lock parking lot maneuver). The clicking noise is generally noted as approximately 1 to 4 "clicks" per wheel revolution. The cause may be interaction between wheel mounting face and wheel mounting surface on rotor.

Recommendation/Instructions:
Complete the procedure below on both front wheels.

Note: It is not necessary to clean the rear wheels for the "clicking" condition.

•Remove the front wheels.
•Clean the rotor top hat as follows.
• 2.1 Use a clean cloth dampened with GM Brake Parts Cleaner 12378556 or equivalent.

• 2.2 Clean the wheel mounting surface of the rotor (rotor top hat). During cleaning process be sure to clean the rotor near the wheel pilot at the center of the rotor.

•Replace the front wheels with the appropriate part number listed below which have a revised mounting surface.
20951880 Painted Wheel

20951881 Polished Wheel

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Is it normal to only experience this on one side? Mine started doing it after 5000 miles it sounds like.

I believe the 2011's have the new wheels. Check to see if your front wheels have slots machined into them - compare to the rear wheels, it is easy to spot.

FYI - my 2011 with the new wheels also clicked, but I recently put a set of black chrome factory wheels on (the old style front wheels, without the slots machined in them) and it's not clicking

Are you sure its 158 ft lbs??? And not Nm? That seems like an INSANE torque for wheel studs...

I have the slots machined into the wheels on my '11 V coupe, and they still click. Also, my go-to car guy said that 158 ft-lbs is extreme and probably not advisable. People would do well to notice that some claim to have fixed their clicking problem by going to 158 ft-lbs, but many others have also claimed to have fixed it and only mention torquing to 140 ft-lbs. 158 ft-lbs may not be the answer, just food for thought.

Yes, definitely 158 ft-lbs. Here's a post that has the latest version of that service bulletin, which clearly states "The wheel nuts should be tightened to a service torque of 215Nm (158 ft-lbs)."

my 2011 has a production date of april. I don't remember there being slots on the back face when I had them off for a wax. They're the satin black rims.

My clicking has not returned either, I am now at 24000 miles. I have changed tires since then as well.

You take the wheels off and wax them?????????

absolutely. Makes dust(which the OE pads dust like crazy), and road asphalt chunks come off 100% easier, and protects it from scratches since we're talking about half-ass painted GM wheels here.
as a matter of fact, maybe the slats *are* there?

That's what I thought it may be by the shape of the fenders.
