Getting a new diff--what should I watch for?
« on: August 19, 2009, 04:57:22 PM »
So as the topic suggests, I am getting a new diff installed today by the dealer.  Apparently the ring gears are trashed.  The good news is this is being covered by my extended warranty and the dealer is covering the deductable.  Aside from making sure they add the friction modifier what do I need to check before I accept the car back?  This is a first 1k 06 sol with the limited slip diff.  Oh and I did mention the later model swap, in case that's possible but I don't know if that will work with the parts they're changing...he made it sound like I was getting a whole new diff though.

Thanks!

Sounds like you have the situation well in hand. I assume the friction modifier is the limited slip additive, so you are good to go.

Since he does not say what year Kappa, then are not all 2007 and beyond cars cover for 5 years or 100000 miles for the power train?.
Is it not the differential part of the power train and thus cover within the period I have specify?.

It sounds like he is getting a complete diff. If so, the Quaife being just the LSD mechanism probably would not be a viable option. The way I beat on my Redline, I am almost tempted to buy a complete diff off of e-bay someday just to have it laying around.

Actually, he said it is a first 1K 2006 Sol. What is REALLY interesting is that the dealership covered the deductible on the service contract. Neat, huh?

Yeah, but as long as they are in there replacing the ring gear, what could it hurt?  They covered the deductible. 

Actually, I was trying to be funny, but think that signalling it with a "LOL" is kind of obvious. 

Obviously, a failed attempt if it drew yet another "correction."

Remember the new car break-in period, that was for the Diff, now be gentle for the next 500 mile, no cruise control and no extended periods of maintaining a certain speed and no speeds over 70mph?

Well, now they are saying the dealer won't cover the deductable...nor did they say that the ring gear is bad, so I'm not real sure what the deal is...they said I could use the powertrain warranty from the dealer but that would mean used parts, or I could use the extended warranty and that would mean 100 dollar deductable...gonna try to argue my way into them paying the deductable since they said they would.  Thanks for the tip on breaking in the new diff, I had not thought about that!

What kind of BS are they trying to throw around here?  :banghead:  Warranty work (to the best of my knowledge) is ALWAYS done with NEW parts .. not used parts.

Let me know if they keep pushing the 'used parts' issue ... I *know* someone to talk and find out the validity of that!

Hold up, little red flag going up. :bs:

Note that the OP said it was a 1sk 1K 2006. His original 3/36 powertrain from GM is now long gone. He is talking about a dealership powertrain warranty vs an extended warranty.

its unfortunate that the ALL the dealers that service cars with this type of diff ALL know that it is garbage and prone to failure, but insist on giving people a hard time on it. it just seems wrong. to this day, every time i put the car away, i look under the car to see if there is a leak and every time i take the car out i take at least a left and right sharp turn at low speed and listen for grinding. This is what it must be like living next to a volcano??????  :goat:

Do you happen to know of anything official/in writing detailing this??

GM extends 5-year, 100,000-mile powertrain warranty to used cars
By James Prichard, Associated Press
General Motors (GM) announced Friday that it will start including a fully transferable five-year, 100,000-mile powertrain warranty on some of its used vehicles.
The new warranty will be effective March 5 on 2002 to 2006 GM certified used vehicles sold by GM's U.S. dealers, the automaker said.

Not the 2006s.  At the start of the 2007 model year they extended it back to Sky's built in the first 6 months of 2006, because they were technically 2007 models. the 2006 Solstices weren't as lucky. If I traded mine in, it was certified as a GM Certified Used Car and then I bought it back, I could have the 5/100.  Since I didn't do that I'm stuck with the original 3/36.

I will have to look into that as I thought mine was certified preowned, but it was bought from a kia dealer (that has other gm stores)...probably not gonna have it since the computer didn't pull it up though....I swear my next car is gonna be 30+ years old so I can work on it myself!

Well, got the car back from the dealer on friday.  I did end up paying the deductable for my extended warranty (100 dollars) but considering the final billed cost to the warranty company was 2500, and that the shop guy said the parts alone were close to 4k to buy personally, I'm pretty happy.  The whine when not under power, clunk when shifting, and grind when turning are all gone.  The car feels a bit stiffer turning sharp, but I'm not sure. Overall, I'd consider myself very happy with the difference!  The car just feels more civilized now.
