Have you had any problems with the Jasper? My dealer said he is going to call GM and request that they buy me a Jasper front diff. Then explained to me that we would part ways. Meaning no more warranty on the front diff . I said thats fine with me.

Well, my dealer called today and said they are out of ideas on the grinding, growling/metal scraping noise in the front diff. Get this!! they are going to call GM and see if they will buy me a Jasper complete front diff, and he explained to me that my warranty will be voided. I am so game for this!!! Jasper has a great warranty, and my troubles, according to Jasper, will be over. I will let you all know what happens. I must say that my Dealer has bent over backwards with me on the problem though. At least they are trying. Kudos for Randy in the service dept. at Weber chevy in Granite City Illinois

I will add a little more that I forgot. There was chunks of metal in the front diff, a ton of shavings on the magnet, and it vibrated at about 75-80, but quit when I let off the gas. I guess I will just be happy that I am getting so many new parts under warranty. I can buy the fact that the noise is 'NORMAL" for sss awd, but is that little normal noise that all the trucks make the cause of the bearings being chewed up, and the shavings? I have read all the post on this, just wanting to know the exact cause. The dealer didn't like my knowledge of the front end problems, and said not to believe this forum, but now is frustrated and said if I can find anything else out to let them know so they can move in the right direction. lol

I have read every post on this front diff noise till i'm blue in the face and I am still baffled. My truck is in the shop for the 4th time. Carrier bearing, pinion bearing, hub bearings have all been replaced under warranty. Today they installed a new viscous coupler bearing in it and it is still making the growling when I turn left or right. They are out of ideas, but are not giving up. Anyone have any suggestions where I could point them for ideas? I have had a Cobalt for 20 days and I hate it!!! Thanks guys
