Third gen front wheel bearing replacement video

Eric O. ftw!!!

Starts right at 0:00 for me, Mendel.

 

20 minutes, it would take me a day lol

 

I liked seeing how that went with an air hammer, since I bought one last winter and I've been thinking that's what I'd try, if I ever have to take on that job again.

It looks like if he had used a hammer bit instead of a chisel bit, he might even have avoided chewing up the old hub like that. (Not that it matters if you're throwing the old one out, but if you ever had a need to remove the hub hoping to reuse it, I haven't thought of any other ways to do it, but that might work.)

But overall, I'm not sure I'll hire this guy to do my hubs....

"If you've gotta take that off, you can probably knock this stake mark out of it if you want to, but we'll see if the impact's got enough mustard here to take it off."

Umm ... sure ... it does ... but that wasn't the point ... the point was to avoid doing what you just did to the end of the axle, which explains why the new nut at the end of the video needs the impact driver to thread on ... and the "proper torque spec" now no longer means what it did ....

In the process of tying a wire onto the caliper (why? to protect the brake hose from damage), stretches the hose right over the edge of the dust shield (3:38) ... ouch! don't look at the camera, watch what you're doing!

The several comments about being careful not to hit the speed sensor wouldn't have to be made if it just got taken out first, which I think is the manual's approach.

I did like the idea of Krown all over the knuckle and hub to fend off corrosion. I've never tried that stuff. Last time, I just used a dab of anti-seize where hub fits to knuckle. I think that should help, but I never had to take that one off again, so I'll never know.

[QUOTE="Mendel Leisk, post: 2624409, member: 69191"I watch with dismay as he chiselled the heck out of it.[/QUOTE]

I watched with relish as he chiseled the heck out of it, thinking the whole time of the ones I did by hand with a slide hammer.

But yeah, I think a hammer end might possibly allow reuse of a hub (say, if you needed to replace a damaged dust shield or rear drum backing plate, but didn't want to replace a good hub just because it's in the way).

Or maybe not ... I suppose it might still really work-harden the parts of the hub the bolts depend on....

It looks like the fronts bolt through from the knuckle, and the holes in the hub have the threads. So, yeah, if he had just applied enough of Big Nasty to rotate the hub until the holes didn't line up, it might have been possible to run the bolts in from the hub side and press it the rest of the way out.

I don't know that that would work for the rears, where I think the bolts go the other way. That might have to be All Nasty.

I actually watched this video before undertaking the activity about a month and 2 k miles ago.

Let’s just say he’s a bit of a show man.

While I do not have an air chisel, I do have an impact wrench, but didn’t use it. Got the axle nut loose with a breaker bar in about 10 seconds, rather than the ~ 2 minutes he was “grinding away” at it.

Separating the rotor and hub assembly didn’t require the air chisel either. Sprayed some pb blaster and let it sit for a bit, grabbed a hammer, screwdriver and chisel and job done.

What he doesn’t show in the video is the damage to the axle threads he has caused by impacting the axle nut off without drilling out or addressing the dimpled axle nut. A nasty surprise if not prepared for that.

Good for entertainment though.

 

Also involved a hammer and screwdriver . But no where near the drama employed in the video.

Probably took 15 minutes a side to remove after a pb blaster soak for 15 minutes.

But Our Prius hasn’t seen much salt in its life .

 

Pleasure.

Planning on undertaking more maintenance on your pampered Prius soon?

 

Well, he kind of does show it, if you're paying attention later in the video, when he takes a brand new nut out of a bag, and needs to use the impact wrench again to spin it on.

There's the rub. That's a method that's come up on PriusChat lots of times before. OK if you're planning to throw out the hub (and you don't separate it). But not OK for any purpose where you might be hoping to reuse it. Even if you manage not to separate it, it is done for as a bearing after that treatment.

Valid point.

Always fun to watch a bumpkin in action .
