Wheel Bearing replacement

I need to do my bearings on my 07 pre runner 4.0L 2wd
But don't really know WHAT Im doing. I can't afford a shop and I don't trust anyone with my truck..my main question is, do I need a special tool?
Thank you.

I was able to do the bearings with very few problems. I had a friend build an H press and literally tore it up trying to press out the bearings, so I just went and bought hub assembly AND bearing all ready to go! They mislead you on that part, but only cost me another 60 bucks! Only bad thing was not having the torque wrench, but I resolved that. So thank you to all for your help and advice. Much appreciated!!

 

No.

But a lot depends on how bad hub assembly is stuck in the spindle.
Mine came right out. But I live in the South East Tennessee, we don’t get a lot of rust.

If it’s stuck on there good, you either have to beat it off with a hammer.
Or borrow, rent, buy a slide puller from a local auto parts store. ( this just makes it easier, but not usually required)

Here is a video that might help.

Here YouTube is your friend. Lots of good how-to videos on that very topic. But frankly, Shop labor should not be too high on R&L Hub assembly replacement. Expect to pay just under $200 pr each side for a good quality assembly. I don't know what the actual shop manual calls out for labor hours. But IT should not be over $75 per side.

 

What these guys said...make sure you buy the assembly and not just the bearings. Don't forget the inner and outer seals, when I bought my hub assemblies, I didn't realize that they didn't come with the inner seals so I had to put off the replacement until the inner seals came in.

 

Shouldn’t have to worry about the seals on a PreRunner?
There isn’t a CV axle. It’s 2WD. I think there is just an O-ring between the hub and spindle.

 

Yes, you are correct...I didn't see that the OP's truck was a 2WD.

 

Which bearings, front, rear, both, only 1 or what? How do you know you need bearings? You state that you really don’t know what you are doing. Replacing bearings is no easy or simple job if you don’t know what you are doing or haven’t replaced bearings previously. First find out for sure what bearing or bearings need to be replaced. Then either find someone who knows what they are doing help you or someone who will do a side job for a price you can afford.

 

There is still the same seal of the bearing to the outer portion of the knuckle no?

 

I don’t know for sure, but it seems like there is a metal filler plate on the rear of the spindle.
I don’t think there is any reason to take it off or out.

I’ll have to look into it.

 

yes that's where the CV axle goes, it's not a seal but a dust cover. Where the bearing gets set into the "hub assembly" of the prerunner there is still a seal, much like they get pressed into the hub assembly of the 4x4.

 

I have to imagine these are the same seals.

4x4 and pre-runner list them on the same diagram

 

There looks to be just the 1 seal.
And it goes in when you build the hub?

 

Yeah, if you buy the hub assembly.
You shouldn’t need it. It’s already in there.

 

for sure, if you get a pre-assembled hub/bearing assembly. I'd still replace the o-ring, but no new "seals" are necessary.

 

That all sounds right, I researched it a while back but don’t remember exactly.
This would be the guy to know definitively,

His picture of the PreRunner hubs shows the o-rings with it.

 

I always encourage going the DIY route but your post doesn't sound reassuring as to your mechanical skills. Last thing you need is to quit 1/2 way during the process then have to tow it to a local shop. There's plenty of help here on TW but it would be good to have an extra pair of hands in your case. It's not a difficult job for those of us that have done this but it is labor intensive. Worse if you are dealing with rust, lack of impact gun, or not buying the whole preassembled WBs. Lastly, avoid cheap local auto parts or eBay ones regardless of the lifetime warranty that local stores lure you with. It's not an install you would want to repeat often.. Look into the ones sold on the forum as posted in the link above.
Welcome to TW.

 

Excellent advice all the way around. I'll add IMHO buy the complete assembly. The guys that lobby for rebuild bearing install either have a good shop with proper tools or haven't run into a seized assembly due to rust etc. It is well within the capabilities of many but not a process we all want to take on.

I took a few quotes from local mechanics on the replacement of L & R front 2012 Prerunner complete Hub Assemblies. Parts and labor with NAPA Gold offerings (Good Reliable Quality) was $525 total. This on paper was $125 over parts cost, less than $75 per side turn key. It would be the best $125 in labor you ever spent in place of setting up from scratch to do the work yourself all things considered.

 

With the loud humming or rubbing sound and rotors are difficult to rotate. For sure my bearings. Left front, cant tell if divers side is bad cuz the other is so loud. But im replacing both. I did get wheel hub and assembly. I am pretty mechanically inclined, and i do have a second set of hands...

 

You should be good to go!...take your time and hopefully there isn't too much corrosion keeping everything stuck together.

Watch you tube videos on the replacement a few times to give yourself an idea of what's involved.
