Replying to: bayou2 (Apr 01, 2007 9:42 am) It doesn't make any sense. It was just checked 2500 miles ago and it was OK. There's no leak according to the dealer, so where did the oil go? I think I would have someone else look at it for another opinion. Also, if the bearings melted to the axle, how would having it in 4wd or 2wd make any difference? Isn't the axle still turning regardless? Maybe they meant the bearings in the differential?

Replying to: bayou2 (Apr 01, 2007 9:42 am) same thing happened to mine at about the same amount of miles. chevy cust service wanted nothing to do with me. I just sent mine in to a mechanic who told me all the guts were busted up like you describe. Could this be a flaw in the chevy? He also told me if i didnt mind no 4wd he would take out the differential in the front, what do you think?

Replying to: bayou2 (Apr 01, 2007 9:42 am) same exact problem i had, Cust service didnt listen cause i was out of warranty. If this is a common problem, why is there no recall?
#5 of 5 Passengerside front axle/ differential bushing????2002 trailblazer by denny9 Feb 26, 2009 (6:43 am)
Around 65,000 miles I started to feel a vibration every time i hit a bump. The vibration would last different amounts of times and eventually go away. I looked at it myself and thought the front transaxle was bad. It was very loose and alot of play in it. After replacing the axle I still had the same problem! I looked a little more at it and talked to a few mechanics, oh yeah customer service at Chevy said they dont know and cant help (figure that one out), and we have concluded it is a bushing or bearing in the front differential. The looseness and play is at least 1/2 inch or more in all directions where the axle snaps into the transmission. Any help or suggestions would be appreciated.
