Hub bearings startred to make a loud noise and transmission front seal started to leak. I have a 2006 chevy silverado z71 with only 41260 miles on it. This should not be happening with so low miles. Tried to get it fixed but the extended warranty I have will not touch it because it is lifted. The probleum existed befor any lift. Th certified person who lifted my truck told me about the transmission leak. I thought the noise might have been the brakes but he told me that the hub bearingd sound like they are dry. I brought straight to trapp Chevrolet the when I got back from work. I guarantee if it was bought with a lift they would of fixed it. I wasnt told that if I lifted it it would void a powertrain on my warranty. This probleum was there berore. That is a loop hole for them. This is wrong.
