Recently I noticed the top of both front wheels are slightly tilting inward. Is this what's called camber, and is it easy to correct? Thanks ahead of time.

 

Yes. The condition you are experiencing is called Negative Camber(where your wheels are as follows: / \ Positive Camber would be this: \ /

 

Take it for an alignment and the camber can be corrected, but since it's a Ranger, they all do have some degree of negative camber.

The big thing you want to watch for is toe in and toe out, as those can eat up tires fast or faster than incorrect camber.

 

Thanks guys. Appreciate it.
