Lenfer's is amazing. I had been told by both dealer and another independent repair shop that the only solution for my leaking differential on my 2011 Frontier Pickup was to replace the differential at a cost of over $3500. I stopped by Lenfer's because they had rebuilt my sons Mazda transmission almost 20 years earlier, and they said they could repair the differential....at around $500. The final bill was less than $500 and the differential looks great, drives great and no leaks at all. Lenfer's is a great option, especially for challenging or "out of the box" types of problems. However, I plan to return for all of my maintenance and repair on my Frontier. They take pride in their work and go above and beyond to find solutions most shops won't even think about.
