"I have been using Wrenchn-It Diesel for over 4 years now. Started with oil change for dump truck, mobile service for replacing hydraulic lines and belts on machines. Seth has always been there on short notice and is a great mechanic. Just a great overall guy and very easy to work with. Highly recommend!"

"Studs broke on my truck called all around nobody was able to fix it or had the time, called wrench it and he said no problem but it will be a wait,the man went pick up studs nuts and rims And came out to me and fixed in the rain. Thumbs up to this guy. All our truck repairs up in this area will be done by them. Highly recommend 👌"
