Recently, we had a Jeep Grand Cherokee in our shop for a brake job. Upon removing the rotor, we found one of the rustiest wheel hubs we have ever seen. In this video, we show you the different hub cleaning methods, and how to remove scaled rust from a wheel hub.

Why is it Important to Clean a Wheel Hub?
Some technicians don't even spend the time to clean the wheel hub during a brake job. It can be a time-consuming process, especially in the Rust Belt where a lot of rust and corrosion can build up on the hub.
But if you skip this step, it can cause an excessive lateral runout of the rotor. This will eventually lead to pedal pulsation. To illustrate this, we checked the runout of the rotor on the Grand Cherokee we were working on before cleaning the hub. The runout was 14 thousandths. The specifications for this application was 2 thousandths or less. This is why it is so important to take the time and clean the hub properly.
Regular Hub Cleaning Process:
When cleaning a wheel hub, a lot of technicians use roloc discs and a wire brush. While this does a good job of cleaning the rotor surface, it doesn't do a good job of getting the area around the studs.
We recommend using a hub resurfacing tool that can go over the studs and clean the hard to reach areas. As always, make sure to give the hub a once over with a wire brush before installing the rotor.
Intensive Hub Cleaning Process:
What happens if you go through your regular hub cleaning process, but there is still buildup on the hub? There are a few options.
You can use a hammer and a flathead screwdriver or chisel to pop the scaled rust off the hub. This is an effective, if not time-consuming process.
However, if you have access to a needle scaler, you can quickly blast the scaled rust off the hub. This will save you some time.

Really love the detailed logic and reasoning behind your actions, when I know why something is done it helps me understand what the final result should be.

@matthewwithey5859 5 лет назад

Super great video, great work on the hub there. Great info. Have a mighty fine day.

@chrisE815 3 года назад

Great video! Mueller-Kueps 460 202 Thin Brake Caliper File works great too! Has a "chisel" end too for getting under the scaled rust.

@gearheadautomotivel.l.c.5476 5 лет назад

Great video y'all. Such an important part of a quality brake job. Could you also take a torch and run an oxidizing flame to help get that heavy scale to just pop off or at least loosen up? Being careful of course not to cook the bearing or fatigue the spindle itself mind you. Perhaps that's too risky but I thought it might be another option. Thanks as always for your time making these videos!

@porkstamina 3 года назад

Thanks for the video, was considering using a needle scaler but wasn't sure if that was safe on the hub.

@stephen6640 2 месяца назад

Wow, who says you don't learn something new every day. That was a great illustration of how not doing something as "simple" as cleaning your hubs can cause you to fail runout by X7.

@soyews 3 года назад

Thanks for the video. I had never thought to clean the hub to improve braking performance. I have the rims off for power coating. Guess I will be using the needle scaler and a thin coat of high heat paint.

@maxcarter3413 3 года назад

Great video. It would be nice to have links to the tools demonstrated.

OTC 8342 hub resurfacing Roloc sanding discs (usually use 80-100 grit brown). 3M ones work and seem to hold together well. I buy mostly 2", but always have 3" for certain hubs and calipers The purple strip and clean are good too. To save on shop supplies use a steel bristle brush (straight and cone) and a fine burr bit (Careful not to take any core material off!) with either a drill or die grinder to work most of the rust off, saving the rolocs for final finish.

Great job, and quality service to your customer. That's how business always should be done.

@mikeeustice4452 4 года назад

When dealing with scale like that as we have in new york warm it up with a torch just to the point where the rust will pop off on its own . don't heat it to much but at the right temp it will pop then go in with your disks

@jankuyper8353 Год назад

Take an old file and grind the end flat ...makes an awesome scraper

@bladder1010 10 месяцев назад

Excellent. What he said makes a lot of sense.

@johnjoseph7382 Год назад

This is a great video. I think only half of the mechanics out there even bother cleaning the hub face and less than 25 percent check for run out and do a finishing on-car lathe to get it within spec.

Sounds like it could just use a new hub altogether

Right... hahashahahahah

@zolox3525 3 года назад

Agree with everything he said. I'm lazy, I would look to change to a new hub and use a nice thin layer of synthetic paste to prevent the issue.

@disturbator 9 месяцев назад

Can u use silicone-teflon paste?

@viplegaleducation1292 4 года назад

What book do I use for runout specs, please, if you do not mind ? I donot see specs for a lot of vehicles on Mitchel1.

@darrenporsch Год назад

An air angle grinder is much better spins at much higher RPM than those drills. That's what I use and I live in New York we get plenty of rust and road salt

@Romulan112 Год назад

I removed the cv joint and there was a lot of rust inside the hub, all around the perimeter. Anyone know what kind of tool to get the rust off inside that circle?

@Eger118877 4 месяца назад

What color of roloc should I use?

@buddyboy4x44 3 года назад

Interesting you said it was one of the worst you have seen. I see lots of Jeep models with what looks like lots of premature rust. I long since decided Jeeps (Chryslers?) are rust buckets.

Total noob here, but what type of tool uses roloc disc's? Also what grit number should you use? Thanks!

3m hub cleaning kit

@nemo5335 5 лет назад

could you put some sort of grease or anti-sieze on the hub to prevent this from happening again?

@mustangenthusiast 4 года назад

3M copper anti seize brake lube

@escottn 4 года назад

Antiseize or a small amount of marine grease.

@johnjoseph7382 Год назад

Fluid Film

@kayleedavenport5052 3 года назад

I never heard any mention of replacing the hub....

@barrysmith8078 2 года назад

Is it worth painting these hubs with heavy duty heat resistant paint for added protection or is that not an option?

@johnjoseph7382 Год назад

just use a slight coat of Fluid Film and you'll be good to go

@JamesNathanielVlogs 4 года назад

How does it even happen

@NhoyBarangay 4 года назад

I would have those studs removed by a Pneumatic Hammer. Grind the entire Hub with a Hub Grinder. That's how I would do it.

@jacklumbar7061 2 года назад

And all the makers had to do was galvanize the thing and none of this would be necessary.

@mikejenniferaloisi788 3 года назад

What kind of roloc discs would one use for this?

@johnjoseph7382 Год назад

3m has a hub cleaning kit, you just have to buy the disks seperately, it's the most popular, you can use a drill or an angle grinder

@kikigem2952 7 месяцев назад

Why not refinish the hub with a high temp caliper paint at that final stage to since its so cleaned up? Is that not something recommended?

@SincerityAF 4 месяца назад

With the tight seal needed between metal, having a painted surfaces might compromise that. Plus when it scratches that's going to cause other problems

@rikunaskali7408 3 года назад

I haven't seen hubs that clean on any of my cars I've owned :D Road salt and proper winters aren't cool.

@AppalachianPatriot Год назад

Clean the hub and spray OSPHO on it. Personally I would have replaced the hub.

@Dangerkiller-D 4 года назад

What happens if all your wheel hubs are like this?

@kyhamoge Год назад

You clean them all! 🤷🏻‍♂️

@stephenyoutubin4476 3 года назад

Plot twist, the hub bearing was toast and had to be replaced anyway.

@garrettguffey2195 2 года назад

needle scaler still peens the surface of the hub flange, i use a carbide scraper, its tedious, but works well.

@user-bp3we5tz1o 2 месяца назад

two thousandths runout is excessive in my opinion.

@colombo0413 2 года назад

Good video but very biased on the sanding tool you barely used the first tool and then gave a tiny cut away then started with the second tool and did a longer cut away as you worked that one for longer to get that scaled rust
