## Customer Reviews

### ⭐⭐⭐⭐⭐ Works as intended. Simple, Cheap and Effective
*by E***R on November 4, 2023*

Figured before I take the front end apart on my truck to replace the auto locking hubs, I would buy this part and replace as a first step. Grinding noise went away and 4WD on my 2014 F150 works perfectly after 250 miles. For $17 and next day delivery it saved me hundreds of $$$ and possible trip to the Ford Stealership.

### ⭐⭐⭐⭐⭐ Perfect
*by L***M on May 29, 2025*

Worked great

### ⭐⭐⭐⭐⭐ Good product
*by R***N on July 23, 2025*

Nice product! Fixed our situation with tge front 4WD clicking in the hub of our 2015 Expedition. Should be easy to install for most people.
