All of the the holes have been helicoil'd and one of them is messed up inside there and I cant get it out..what should I do? The other 5 are torqued to 75 ft lbs.

I wouldn't, probably be out of balanced and tear up ur bearings

Sounds like a bad idea... Just do it once fix it right.

Ahh man! I would say one of the worst areas to have stripped threads. I don't know how reliable heli-coils would be in that area...But definitly DON'T run it with one missing.

You would probably not suffer any issues, but don't risk it. I would go as far as paying to have it professionally repaired.

Agreed, no bueno! You will see a greater potential for deformation and flex of the flywheel because of the lack of this bolt. Additionally, this could, in time, cause other bolts to see greater stress than normal causing the back-out or fail. Do it right or expect to do it again!

This is where you gotta stop and think... If 5 bolts were OK, then why would the engineers who designed it put in 6? (Car companies are the stingiest entities on the face of the earth and they never add unnecessary parts/cost/weight to their products.)


You should have some options - but what does this mean? Did the coil go in wrong? Is a bolt in wrong? Was the coil threaded in properly? Do you have a picture?

Not that I disagree with anybody about only running 5 bolts being a bad idea, but care to explain why GM felt the need to run six lug hubs on the 04-07 CTS-V's Lol

You'd have to ask the engineers who built it, but I'll bet the car's weight has something to do with it. She goes really fast and is a little heavy. It doesn't surprise me that a car that is 21% heavier than my F-Body needs 20% more lugnuts to hold the wheels on.

ever seen what happens when a flywheel or flexplate does when it comes off? this is why i want to invest in a tranny blanket or somethin for added safety. i enjoy having two legs and feet lol.

Really I was joking but since you replied, what about the 09+ CTS-V lol? It's heavier and had 156hp more and only has 5 lug hub.

The SRX shares the 04-07 CTS-V lug pattern and its just a slow poke V6 SUV. I think somebody had some spare part's to get rid of is what I think lol

Yea. I'm on a personal mission to get cars lighter. I was curious, did the math, and came up with a clever BS answer that no one could dispute. lol


I think you are correct here. My expectation is that lug nuts and studs are decided more by the design department (on cars) vs. the engineering department because they are visible on the exterior of the car. (Designers were so concerned about them on my Firebird that they spent several dollars to put decorative plastic caps on them!)

We could probably do a study of the number of studs, the diameters, and the torque applied to tell what the true strength difference is.

Beyond strength, balance probably also plays a role in rotating parts. Leaving off one nut or bolt could cause a wobble, which is usually a bad thing...

Suprfast

No. It will be out of balance in my opinion.

Why are you torquing a lb over max? Suppose to be 74 ft lbs... Also you have messed up threads? You stripped them out? Not to sound like a bad guy but maybe take a step back and figure out if this is something you should be doing... Also so..use 6. Take one of the bolts down to ACE or your local hardware store and they should be able to get you a bolt.
