#13 of 28 valanche transfer case leaking
Sep 03, 2008 (3:11 pm)
I have an 02 Avalanche that had a leaking transfer case. My dealer wanted 1350.00 to replace the case. I went to a local transmission shop and found that at around 80,000 mile THEY ALL WILL LEAK. There is a flaw in the design of the pump inside that allows the pump to slam back and forth till it beats a hole in the case in 4 places. My DEALER knows of NO problem,???, however 4 transmission shops have shown me dozens of cases that have done this and a repair kit is avalible to correct the flaw. Has anyone had this happen??. Mine was repaired WITH the kit for 635.00
#14 of 28 Consistant front end noise problem
Sep 04, 2008 (6:57 pm)
I have had a never ending problem with a vibration in my 04 Avalanche. Today it is in the shop again after having taken it in 6 times within the last 2 years for the same issues. Each time they tell me its normal and give me Bulletin # such as # 1874365 , # 03-08-61-002h and #06-08-61-003a
The following is a list of some of the things they have done to try and reslove the issues as of 01/09/07 Interm Shaft Exercise/Stroke 01/31/07 Crossmember front suspension replace, 03/15/07 Pump assy , power steering - replace, 03/15/07 Hanger and or clamp exhaust system replace, 05/25/07 Lubed balljoints, tierods, pitman, idler arm, service tech still noted hearing issues they showed me bulletin # 03-08-61-002h AGAIN, they then removed the front crossmember and lube and added washers performed road test then found bullentin #06-08-61-003A and then they installed body mounts.
Today the service department checked my truck again and of course was quick to say NOW I am out of warrenty. After long debate and calling Chevy Customer service and opening a case they are going to fix the issues that were long reported BEFORE the warrenty expired. Now they are saying they are replacing the Interm Shaft (instead of just exercising it like the did in Jan 2007) and they are going to re check the suspension.
My advice if you are having issues keep taking it in, Keep getting it noted and if the issue is not resloved to your satification call Chevy Customer Service at 800-222-1020. That way when you are out of warrenty it showes you were trying to get it resloved when it was still in warrenty.
Cross your fingers that this time when I get it back it will be repaired (I HOPE) and no more Bullentins
#15 of 28 Avalanche Drivetrain Rattle
Feb 26, 2009 (2:48 pm)
I have a 2003 Z71 Avalanche with 99,500 miles on it. Just recently, I heard a very metallic rattle coming from below the truck while driving. It was at low frequency at low speeds, and increased in frequency until about 25mph, and then went away. I figured it was a heat shield that broke loose, so I looked underneath and everything seems secure. The noise is not made if the truck is being revved in park...only while driving - I think that rules out the cat/exhaust. It happens in 2WD & 4WD. Any body have a similar issue?

Why would it rule out the catalytic? My Jeep's catalytic sounds like a can of marbles when driving, but quiet when idling.
Take a rubber mallet to the catalytic. If it rattles, there's your problem.
You may also want to check the various fittings/connections to see if anything is loose. I've had rattles that I was SURE are suspension, but it was just a d-shackle swinging when I applied brakes/gas.
Have you had any maintenance or mods done recently?
#17 of 28 Wheel Bearing?
Mar 16, 2009 (12:42 pm)
I had a similar issue starting at 106K miles. Sound was heard under 25 mph and was intermittantly more pronounces as I made slow-speed turns. I suspected that it might be a front brake part dragging. I had the brakes inspected. Brakes were fine, but not the wheel bearing on the drivers side. That cost $420 to repair including AAA discount. BTW - any brake jobs I suggest replacing with ceramic pads rather than bi-metalic pads. They are worth their weight in new rotors!

Durastop pads and rotors. Incredible performance - and from GM.
#19 of 28 high speed vibration
Sep 13, 2009 (4:00 pm)
I have an '02 avalanche. It just started moderately vibrating between 63 and 73 miles per hour. Slower is ok and faster is ok. Bought new tires in April and haven't had any problems until now. Jacked it up and nothing seems loose, tires have no bulges or defects on the outside. Alignment? Help!

Did you get an alignment? If you lifted it, the front wheel camber will be off and will need an alignment or the outer edges of the tires will cup and you'll get vibes.
#21 of 28 Wierd Avalanche Noise
Dec 03, 2009 (9:43 am)
If I apply the brakes and stop with the wheels turned left or right (as at a 'T' intersection) there is a wierd noise like a brake dragging or a locked-up differential. It's wierd because it doesn't make the noise if the wheelsremain straight when stopped. I can then turn them and there's no noise. What gives?

I have the same problem. I replaced the rotor and pads and I still seem to have the same problem. Are the pads supposed to slide easily on the rails? To move the pad on the inside of the rotor I must tap it pretty hard. Is that normal? The outside one seems to move by hand with slight resistance.
