Ok I have read what I found I understand why I have this condition, it is also unbearable. 3rd gear in the rain getting on the highway I almost chipped a tooth.

My question is can we still go to the dealer and have them put in the stiffer bushings as the tsb says if we are out of warranty? Has anyone tried this? Or do we have to bite the bullet and buy aftermarket ones?

I don't mind doing things myself but if I could get a recall fix done for free ill take that any day.

Thanks guys

The GM bushing in TSB was a failure - it did not reduce wheel hop and introduced significant noise. Many, perhaps most, who tried them ultimately took them out.

Get the revshift poly cradle bushings. Many have reported they are a near total cure for hop.

I have read this however I wish to know if anyone has recently gone to gm for the tsb fix? Last posts about it were several years ago. Free stiffer bushings would be nice. Happy to upgrade other things later if necessary.

Iirc the tsb was for the 4/05s only by 2006 gm put different diff bushings
When I had my 07 in the dealer there was no wheel hop tsb on the 07
Go with axles and cradle bushings , the 2 will elimate 95 percent of your hop

I went with Hendrix axles first and they elimated 50-70 percent of the hop
I since then have purchased cradle bushings from revshift

It won't hurt to ask a dealer, but I don't think the installation of GM bushings, assuming the parts are still available will be "free." It is a Technical Service Bulletin, not a NHTSA recall. A TSB tells the dealer how to respond to (make repairs for) a specific customer complaint but it is not a mandatory fix.

Ok thanks. I figured as much but I may call a few dealers anyways. If a phone call saves me $300 and a day or two it's worth trying. Too bad it wasn't a recall!

No, this is old information and faulty logic. Listen to darkman. He is one of the main experts on this forum and knows this car better than almost anyone else.

It doesn't matter. The GM TSB fix doesn't work. The revshift cradle bushings work. Do that instead. Honestly, are you even reading what people are writing to you?

Yeah I read that which led me to start this thread. Apparently I value aggressive driving ha. I'm wondering when was the last time someone got this done for free.

I was reading what people were saying, doing this on my iPad and missed dark mans original reply just saw yours. Other threads said 75% cure, read about noise but not anyone removing the fix. Not my first car or forum. . . But my first iPad.

Thanks for the info guys.

Wheel hop in this car is better than traction control and stability control combined. It will keep you from doing anything stupid in the rain in 3rd gear. My stock '05 diff has survived 80k maggied miles and counting and I get equal mileage from my front and rear staggered width tires.....
..... I love wheel hop! Keeps me from doing stupid things in 3rd on dry pavement. ;)

If you want to light up the tires put in an 8.8 or 9" or buy a different car. My '96 Impala SS was the king of burnouts, powerslides, drifts........ it's a good thing I got those out of my system. 2 sets of rear tires to each set of fronts was getting old.

Seems to be a combination of a few things. I have the BMR AWK (cradle crushers and bar) and the CS diff block with CS bushing on Pirelli P Zero Nero all seasons, 275 40 18s.

LOL but seriously... From what I've seen, seems it varies based on tire, suspension setup, and driver. Some don't seem to ever encounter it. Some seem to always encounter it even at odd times.

Here's another it's-a-waste-of-time comment: GM cradle bushings were not effective. As free as they were, they were a waste of time.

My Spectre Werks cradle bushings plus the Hendrix/DSS axles have been 99+% effective in eliminating WH. Get the current equivalents of these (Revshift and Gforce), and (to quote Naf) call it a day.

I'm sure my cheap tires are no help at all, when I got the car it had mismatched tires. I'll keep them till I get snows for the winter then I plan to upgrade for next summer. Add that stock suspension with 95k on it (not sure if shocks are original) and I bounce a little. Not when I slide sideways but when I go hard 1st, 2nd, and 3rd shift dry or if I try to drive the car in the rain it hops.

Sounds like a plan, that will be my project later in the summer.

Just get the GM replacements done for free, that makes a ton of sense.

I have gforce axles, and revshift cradle bushings, and I don't hop whatsoever.

My wheelhop was so bad I bought the BMR AWK kit. When I was installing it I found that I already had the GM TSB inserts in there. They are completely useless and a giant waste of time..oh and they squeak and creak going over any kind of bump. The BMR kit got rid of 25% of the hop. I ended up getting Gforce axles which got rid of another 50% of the hop. I ditched the BMR kit and put in Revshift cradle bushings and trailing arm bushings and my hop is completely gone on Dry pavement.

I'd recommend Gforce axles and Revshift cradle bushings.

Alright I'm convinced, that will be my course of action.

On another note has anyone found a way to set the traction and stability control to always off unless you turn it on? I find it a little annoying to turn these off whenever I want to "drive" the car (which is most trips). I'd rather have to turn that stuff on when I want it (10% of the time).

Before we get off track no I'm not always driving like a nut, just don't like the little issues when this stuff tries to drive the car for me, i.e. accelerating on a ramp and go over an expansion joint and TC comes on and cuts power for a second- not necessary.

I haven't heard of anyone being able to change the default traction control setting. I'd love to have Competitive driving mode as the default.

Would be awesome if a three position switch could be used to set the mode instead of the button on the steering wheel.

Guys in V2 also complain about not being able to be in sport mode upon startup. No one has made any fix.

Unfortunately it is a legal/government requirement to have full Electronic stability control and traction control upon vehicle startup on passenger cars. Generally the only exception is vehicles equipped with a 4 wheel drive system that has a low range transfer case.

Too bad, would have been nice. I played a little in the rain at work today, no wheel hop when I'm sideways which is nice. Based on how slippery it is in the rain I am not looking forward to driving to work in the snow. Definitely getting snows in the winter.

Can you post a link to these two products? I'm also interested in fixing my wheel hop.

You won't get hop when sideways and drifting. Each tire is spinning at different revolutions.

I see alot of people saying axles fixed 50% or so then with revshift bushing its completely fixed. Has anybody done cradle bushing without axles? Maybe the cradle bushings are a 98% fix by them selfs and the axles are not needed.

I'll be testing this soon enough. My car was in the shop recently (long story) and needs new diff bushing and upper control arm bushings. I figured as long as I'm in there might as well do the whole Revshift set so I ordered trailing arm and cradle bushings as well. I'll report on the change whenever they show up.

My car is in the shop right now getting all revshift bushings. Should have an answer this weekend or nexy

The reports on the Specter Werkes bushings that only worked in the 2004-2005 models varied. A few reported the near elimination of wheel hop (Twitch), but most reported only partial reduction of wheel hop. This fix preceded the axle option by a number years and there were quite a few that tried them.

(I installed the axles first, and they eliminated 100% of my wheel hop. I installed Specter Werkes bushings later for their other benefits.)

I have not seen any reports for the newer, more complete cradle bushing replacements. I am somewhat skeptical about their capacity to totally cure wheel hop mostly because GM resorted to the asymmetric axles with the V2, which suggests that a stiffer cradle attachment is only part of what is required, but I could be wrong.

The Spectre bushings reduced the hop for me by about 35-50%

I just got done installing an eps cam, headers, ported heads, mm, transmission mount and revshift rear cradle and trailing arm bushings. So far my wheel hop is 98% gone. I have not dropped the clutch yet but have taking off from a stop and just got wheel spin. This was not the case before. I had terrible wheel hop. I will do some clutch dumps later in the week and report back. If things stay they way they are I say the axles are not needed to get rid of the hop.

I have the Delrin cradle bushings and stock axles. I still have some wheel hop but only with very aggressive acceleration - so I would say in my case, cured more than half of the annoying wheel hop. I still can't launch the V so forget about a clutch dump.

There are a lot of combinations to mitigate or even completely eliminate the wheel hop. The delrin or poly cradle bushings is a good start. I skipped all the axle stuff and opted for the CS 8.8 (which I plan to install once I get a full weekend to myself). My decision going that route was because it cures the wheel hop, eliminates the parade clunk, and capable of handling a clutch dump with ease - and adding more power later.
