I've got a 99 rodeo that has a wierd clunk from the drivetrain. It happens after you take off from a stop. It is felt but not heard. It's a v6 4x4 with an automatic, 80,000 miles and a fairly easy life up to this point. Is this common? Also wondering if any of its other problems are common to these vehicles. The four wheel drive doesn't like to disengage. I lost my power steering the first time off road. Appears to be the rack. Has a hole in the boot and a fluid leak.
