One problem related to transmission noise has been reported for the 2005 Chevrolet Suburban. The most recently reported issues are listed below.
First the transmission failed right after I purchased the vehicle 2 years ago. I had to buy a new transmission that wasn't cheap around $3,500. Then the front wheel bearings started with the right side last year just had a ton of play in it my mechanic found it when lifting up my truck for a tire rotation. Then the left front wheel bearing just started making a load roaring noise but had no play in it at all that I could feel when checking it out. Both cost around $250 a wheel to replace. Now my 5. 3 liter engine is having a knocking sound when at a stop after driving about 30 minutes or when the engine is hot. Also I am hearing a slight ticking sound from the engine cold or hot. I have 4 small kids so I need a very reliable large vehicle and this is Suburban is driving me and my wife crazy having to poor money in this vehicle every year. I am the soil provider for my family I cant afford putting all my money into a vehicle like this.
