This is the one.

Controlling Rear Axle or Wheel Hop on Full-Throttle Application from a Standstill and/or Full Throttle 1-2 Shift (Install Supplementary Rear Sub-Frame Bushings) #05-04-114-001A - (Jul 18, 2005)
Controlling Rear Axle or Wheel Hop on Full-Throttle Application From a Standstill and/or Full-Throttle 1-2 Shift (Install Supplementary Rear Sub-Frame Bushings)
2004-2005 Cadillac CTS-V

The information presented in this bulletin is intended to inform, educate, and provide an effective means to further improve the outstanding high-performace handling qualities of the CTS-V for customers who value very aggressive driving capabilities.

This bulletin is being revised to expand the title line, include additional information, and add a repair procedure. Please discard Corporate Bulletin Number 05-04-114-001 (Section 04 - Driveline/Axle).

Condition
Some customers may comment on rear wheel hop or rear suspension bounce under full throttle acceleration. This condition is not unsafe by itself and is the result of very aggressive driving practices. This condition is primarily confined to hard acceleration from a standstill with wide open throttle, though it may be possible to induce if the customer attempts a hurried wide open throttle or "Power-Shift" from 1st to 2nd gear.

Notice: Vehicle component durability is greatly influenced by these driver abuses. Driving in this manner is not recommended.


Customer Expectations and Real World Usage
The CTS-V is a very high performance vehicle capable of class-leading acceleration that, in most cases, exceeds even the capabilities of pure sport and muscle cars. The 5.7L V8 engine in the CTS-V provides outstanding reserves of power. This large available engine torque, coupled with a suspension system and tire combination designed for maximum road adhesion, may result in wheel hop under certain conditions.

Cause
In the rear of the CTS-V, a sub-frame is mounted to the body structure at four rubber-isolated points. These mounts were carefully chosen to achieve an effective combination of excellent handling, while retaining effective damping of road shocks and bumps. The force of the suspension rapidly occillating vertically (hopping) provides enough weight transfer (up and down) that these bushings, which normally compress to help isolate passengers from irregular road surfaces, may deflect or compress in sympathy to wheel hop.

Correction

Improving High Performance Suspension Characteristics
For customers who value very aggressive driving capabilities, a revised set of firmer rear sub-frame bushings are available that may provide an incremental improvement in reducing the tendency of the rear suspension to wheel hop. This is an improvement that will further extend the handling capabilities of the CTS-V - it will not remove the possibility of wheel hop in all situations.

Important: Do NOT replace the rear sub-frame bushings unless the customer specifically has the concern of objectionable wheel hop.

I had no noise....but they lost their stiffness after about 1500 miles and were pretty useless by 3000 mi after install.

If your dealer doesn't know about it then this might be an indication to find a dealer who does?

I'd hold off a little while - my dealer assures me there is a replacment bushing coming because the anti wheel hop's they installed months ago squeak like hell and have to be lubed about each week (in the cold anyway).

There have been several reports on noise from the GM inserts mentioned in the TSB.
I have still not heard any word about updated parts but I'll keep my ears open.

James put the Spectre bushings in his car and I think he said that he hasn't heard any noises.
I did another Spectre install on a customers car last weekend and except for the fact that the exhaust was moved too close to the propshaft (sorry 'bout that) he has had no noise complaints either.
The Spectre is thicker, and definitely stronger.
If I find anything out I'll post it.

Ewill3rd installed the Spectre bushings on my car (along with the UUC Shifter) last weekend, (no worries on the exhaust, simple fix at home). I've only had one chance to really test both items (5 very quick runs to 145MPH), but so far, the bushings do not make any noise and wheel hop is reduced by ~50% or more,depending on clutch release technique. The UUC shifter is the big difference maker, no more "fishing for gears", each shift is as crisp and clean as anyone could ask for, right behind a StealthV tune for mod/$ :thumbsup:

so basically they're poly bushings, those dont squek too bad, I use them for my front and rear bars in the camaro....but really if they squek bring it back, if it still has wheel hop, bring it back....thats what warranty is for right? I just cant see spending money on something, when I can get it for free....trust me I have nothing but BMR on the camar, love em. its just that free>pay for something.
