Drivetrain Noise at Highway Speeds
This is my first ZJ and so far I really like it. It is a 97 with the 5.2 and the np249 with 135,000 miles. I'm hearing a growling noise at highway speeds that is coming from somewhere in the front end. It almost sounds like tire noise you would get if you had a lower ball joint out. It doesn't seem to change if I swerve back and forth. I jacked up the front and and I couldn't detect any play in either of the front wheels. There is no abnormal tire wear. It does have a slight pull to the right but I don't think that's related. It probably just needs an alignment.
I'm not really asking for a magical internet diagnosis but wanted to ask where how to start troubleshootnig. I've had 2 XJ's before an neither one did anything like this.
