Pull it apart and look. If you have grease on or around the backing plate and brake parts you have a bad inner seal.
I am about 99% sure your 2011 Puma has Lippert Axles. Lippert uses the cheapest single lip grease seals they can find. I have replaced a few them for people and its a well known issue.
You need to get the axles weight capacity and determine if it is a Lippert axle. A wild guess is you have 5200 lb capacity Lippert axles and the inner seals are Lippert part # 122088 which cross references to National# 442109 or Dexter #
010-054-00
Take the old seal if you can remove it without boogering it all up, and part number once you know for sure (it should have numbers etched on the seal itself), and go to NAPA. Have them cross reference it and try to get either Timken, SKF, or National. The important thing is you want a double lip seal. Sometimes cross referencing those Lippert parts is a tough nut.
