Try Doing It the Wrong Way

Today’s article is composed of two quick tips that are distinct and different, but interrelated because they’re used on the same items: the humble fasteners we remove and install hundreds of times daily. These tips are both geared to newer techs since we all must find...

Modern Power Window Switches: Smarter than You’d Think

When was the last time you rolled down the power windows in an older car or truck? I’m talking at least pre-2000. The older, the better. As a passenger, you’ll find that every door has a mix of buttons, switches, locks, and handles to mess around with, plus maybe a...

It’s All About the Process

Man, it feels like just yesterday you graduated with that Associate’s in Automotive Tech, but nope, it's been three months already, and you've landed a solid job at ABC Auto Repair back in your hometown. The boss has been taking it easy on you, dishing out a bunch of...

Dealing with “System Lean” DTCs

The Engine Control Module (ECM) is always keeping an eye on the amount of fuel it is adding to the cylinders, and it'll throw a code when it figures it can't keep the mixture right where it needs to be. You might see codes like "system rich" or "system lean," and they...

Back Away from the Wrenches

Today’s article is more of a philosophical one than a pragmatic one. You see, we’re in the business of buying and reselling auto parts, servicing automobiles, and getting paid for our efforts. But as automotive professionals, we merely delay the inevitable. The...

The Misunderstood Ford 6.0

My wife and I are RVers and started our RV adventure with a 23’ toy hauler. When we started, we pulled the trailer with a Ram 1500 equipped with the 5.7-liter Hemi engine, and for most outings, it handled the task just fine. It wasn’t until we took a trip to the North...

Side Business

If your shop is a typical one, you wouldn’t turn down easy, profitable work, right? Of course not. Maybe it’s time your foreman, techs, and service writers sat down and talked through the car that isn’t a car: side-by-side (SxS). Like other not-immediately-obvious...

The rarely seen control arm-mounted trailer ball rears its head

by | Feb 14, 2023

Well, this was a humdinger. Let me explain how I ended up here.

Ball joint stud stuck in lower control arm

Class 0.25 towing capacity, maybe? Photo by Lemmy.

I was popping ball joints free from the lower A-arms so I could swing the CV axles out and replace the hub assemblies on this car. The left side freed up with a few taps. This side? Well, this picture is after the hammer, then the torch, then the big hammer and the pickle fork. Finally I separated the control arm from the knuckle using a homebrewed tool.

This wasn’t the way I was expecting to do it, though. As you can see, the ball stud actually fractured the socket, releasing it. This resulted in the ball joint breaking, rather than the stud end coming free of the lower A-arm and being able to be put back into service. At least in this position I was able to put the ball joint press on it, but it still had some fight left in it. After turning the press’ hex with The Persuader (my four-foot breaker bar) with a three-foot pipe over the handle, it cut loose.

Well, this is gonna be a fun job, I can tell right now. Image by Kyla Smith-Campbell.

And yes, for all you smartypants folks who will ask, yes, I certainly did remember to take the nut off before I started! On the bright side of the job, the bearings fell right out with very little fanfare, so at least I had that going for me.

Have a good Monday! I hope the rest of the week doesn’t go like this.
