ball joint spins when tightening nut

Today, a lot of car users have come across this common problem. And that is the ball joint spinning whe tightening the nut.

So, this happens due to reasons hiding behind. And these are in fact the common issues driving this problem. So, why does the ball joint spins when tightening the nut?

Well, the reasons that are responsible for this are covered here. We also got here the solutions that you need to resolve these. So, take a look.

Reason 1: A Low Pressure on the Arm

Whenever you take off or replace the ball joint nut, you need to tighten it. Like, you put it back by trying to tighten it properly.

But that is the main time when this problem arises. Like, you may not have given the proper pressure that it needs.

Say, you started tightening the nuts to the ball joint. But this would keep on rotating. Because the lower control arm is not having the proper pressure that it needs.

When you are tightening the nuts into the lower arm, the pressure needed is significant. And most car users fail to provide that. 

As a result, the nut does not get properly fastened to the joint shaft. And that is when you keep the ball joint nut loose. 

For this reason, the ball joint starts spinning when you are tightening the nut.

Solution

To fix this, you do not have to do anything out of the box. Rather, you just have to make sure that you give significant pressure to the lower control arm.

You have to see if the lower control arm is properly placed or not. And it also has to be tightened or fastened properly.

What you can do for this is to use a jack under the arm. Keep it very close to the ball joint as much as you can. 

This helps to get more pressure as the vehicle weight pushes towards the joint. And do not forget to use a jack stand when you use the jack here. 

Or else, this could be risky to operate. So, this is how you may fix the issue.

Reason 2: A Bad Lower Control Arm

We have already come up with the first reason for this issue. So, we know that there could be issues with its tight or loose connection.

But it is not always the connection of the shaft. And it is neither the pressure on the lower control arm as well. There could be even more than that.

That is, there are a few times that users may find a lower control arm defective. 

Solution

So, a defective lower arm control unit is nothing very rare. It can be damaged anytime as it is something internal. 

Like, you would not have control over it at times but may still get affected. In that case, the department has to be looked at by an expert. 

They would surely give it a shot to get fixed or repaired. But it might not work all the time. As a result, it might also be needed to be replaced from time to time.

Reason 3: Fuel Leaking from the Fuel Tank

When someone sees the ball joint spin when tightening, they always think of the shaft. In addition, some experts may also come up with the idea of lower arm control.

But almost no one can understand that it might also happen for something silly. It is silly in a way because the reason might not seem connected in any way.

So, it is a defective fuel tank. Yes, you read that right! A defective fuel does not mean it is completely damaged. Rather, it may have a few issues that can be fixed shortly.

And due to the issues, fuel from the fuel tank leaks at times. As a result, the fuel comes down all the way to the ball joint. 

That’s why you may see that the ball joint spins when you are tightening out. 

But do not forget that it may also happen due to a faulty filter. However, it is not a very common one to experience.

Solution

For a leakage in the fuel tank, you just fix the leakage. To get started, find the leakage properly. See, if there are multiple or only a single leak. 

Remember that finding fuel tank leakage might not be an easy thing to do. Once you locate it, sand it down. After that, clean the surface with a bit of water splash.

Now, take epoxy to put it in the leakages or holes. Prepare the epoxy accordingly and insert it into the hole. If there are multiple holes or leakages, go accordingly.

Once you fill up the holes, you are done. Now, you can refill the fuel tank to check if the issue is resolved.

And if you think your fuel filter is defective too, just replace it. Replacing a fuel filter is actually nothing to think about.

Now, trying to get an epoxy for your car? Here’s an idea.

Hope this helps!
