Hello. I’m a newly sighnee and need your help guys. I just bought a 2003 Yukon XL Denali and in deep shaite. I was told by the mechanic that I have a broken front sway bar. This is not the worst problem though. The previous owner lived on Cape and the bottom is all rusted. I just (Mechanik) welded a subframe, don’t know what it is, and was told that I can drive like this very slowly and don’t make any sharp turns at high speed until I can replace those parts. Now can you guys tell me if it is safe to drive like that? Also can I fix the rust so it wouldn’t spread and is this all worth it? The car drives and everything is fine as far as interior and drivetrain goes. Any helpful advice would be greatly appreciated. Thanks.
