A Serviceable Spindle That Will Save You Time and Money

Having a damaged spindle can be an expensive and time-consuming fix. However, United Axle has invented a solution to this problem with its serviceable spindle.

Recently we interviewed Todd Carroll, Founder, and President of United Axle.

Axle Spindle Damage

Historically, when an axle spindle is damaged, there was no way to repair or service it. The spindle was not replaceable, so in order to repair it, you would need to replace the entire axle. This can be a very time-consuming and expensive fix, which means unexpected downtime that you have to make up for.

A New Solution

Thankfully though,  United Axle came up with a solution to this problem.

He goes on to explain how it came about,

“I started focusing on it, trying to find a way to make it more serviceable. Finally, we came up with the idea to put threads on it… When we ultimately came out with this process, it started out in just my area to make a little extra money on the side. We went to a local truck show, and then it blew up in our face. We had a manufacturer get ahold of us who wanted to start putting it on some of their busses. People liked the thought of a replaceable spindle.”

A Unique Design

However, with any invention, there are hurdles that come up. In the case of this, they saw what their competitors were doing, and know about the patents that they had. United Axle then had to think outside the box and come up with a completely new and unique idea, to put threads on the spindle. Not only does this mean that you can service your spindle without the unnecessary cost of replacing the whole axle, but it also means that the service time is drastically less, saving you time and money.

Whenever you start welding a foundational piece of a truck like an axle there is always some concern about the integrity of those repairs. But, how does United Axle meet or exceed the safety requirements on an axle?

At the 9:31 time mark, Todd said,

“We have a 3″ x 3″ threaded lug on the backside of our spindle. When we thread that spindle in, we torque that thing to 800-foot pounds. Once it’s torqued down we come back and we weld that spindle, just as if a piece of pipe was being welded in the industry.”

Truck OEM Adoption

In time, we may see this technology used by truck manufacturers. In fact, United Axle was having those conversations before Covid-19, and even though it slowed down, they are excited to continue those conversations soon.

There is so much information we can take away from our interview with Todd Carroll of United Axle. But if there is one bonus piece of information to take away from this, it’s the importance to educate yourselves. There are lots of tools on the market that were never there before, and with the help of the internet, there is no end to our ability to improve our knowledge.
