🍂 DON'T PARK THE PROBLEM FOR WINTER.
Labor Day may mark the unofficial end of summer, but before you park the boat or camper for the season, now is a great time to take care of the maintenance and repairs you’ve been putting off.
Every spring, our schedule fills up with boat trailers and campers that need to be ready right before Memorial Day weekend. If you already know something needs attention, why wait until then?
September & October Special:
🛥️ Boat Trailers
🏕️ Campers
🔧 10% OFF installed parts when you schedule your service with MT Axle Supply during September or October.
And if everything seems to be working fine? A bearing repack is a great place to start. We recommend having your trailer wheel bearings serviced at least annually. It's also an opportunity for us to inspect what's going on inside the hub before your trailer sits for the winter.
Brakes, bearings, suspension, lights, wiring—or that little problem you noticed all summer and kept saying you'd get to later—this is later. 😉
Get it taken care of this fall, park it for the winter, and when spring rolls around you'll be that much closer to hooking up and going.

🔧 Reference Guides — Save These!
We share information like this with customers all the time, so we figured—why not share the wealth with everyone?
Here are the three MT Axle Supply reference guides we recently featured:
📏 Spring Axle Dimensions — Hub Face & Spring Center
🛞 5-Lug Bolt Pattern Measurement Guide
🛑 New Trailer Brake Care Guide
We’re posting the full-size versions here so you can screenshot them, save them to your phone, or share them with someone who might need them down the road.
Sometimes having the right information handy makes figuring out what you need a whole lot easier.
And, as always, if you're still not sure what you've got, give us a call or send us a message. We're happy to help.

What other trailer reference guides would you like to see us make?

🔧 A little trailer information worth saving!
We get a lot of questions about measurements, bolt patterns and proper brake care, so we've been working on creating some simple reference guides to make that information easier to find.
📏 How to measure Hub Face & Spring Center
🛞 How to determine a 5-Lug Bolt Pattern
🛑 How to properly break in and care for new trailer brakes
Save this Reel for later, share it with someone who works on trailers, or send us a message if you need help figuring out what you've got.
We're working on more reference guides, too—what would you like us to cover next?

MT Axle Supply phone number is back up and running.

📱 Well... we survived the heat and the Richland County Fair, but unfortunately our business phone didn't. 😅
We're traveling today and are hoping to have the issue resolved by tomorrow. In the meantime, if you've tried reaching us by phone and haven't heard back, we apologize.
Our phone's screen is completely unresponsive (and won't even let us shut it off), so we're a little limited until we can get it replaced.
If you need to get ahold of us in the meantime, please send us a message here on Facebook Messenger, and we'll respond as soon as we're able.
Thank you for your patience and understanding—we appreciate it.

We were sad to see DeeDee go, but her family is happy to have her back!

This cute girl is hanging out with us at the shop today. She's been here since at least 8 and doesn't seem in a hurry to go back out in the heat. She has AC, water and food for the day, but if you know her I'm sure she has a family missing her.
