Whats up family I was a member of this forum a few years ago and had a 1999 tahoe Loved but had to let it go. A good friend of mine is considering to sale me is 2003 escalade for around 2 grand. He says the engine and transmission is very strong and it needs work on the front front differential so I have a few questions. 1. worst case how much will it cost to get the front differential repaired. 2. what else to look for wrong on the truck 3. do these tend to have the head gasket issue of the earlier years. I hope t all works out and I can come back to the family lol
