I have done this twice on my fx16 which is the same as doing it on the rear of the mr2,

You will need a shop press, bearing splitter plate and wheel bearing installer/removal kit( has various size dies and cups to support the knuckle while pressing)

First thing is to remove the knuckle.
( unbolt ball joint, strut, rear tie rod, cv joint)

Second part is support the knuckle and press out the drive hub. You will then use the splitter plate to remove the outter race that is still on the hub.

Next you need to remove the wheel bearing seal and snap ring that retains bearing in knuckle. After that you can position the knuckle in the press and press the bearing out.

To install the new bearing press it into the knuckle and install the snap ring and wheel bearing seal, then you will need to install the drive hub.

You need to support the bearing from the inner race as you press the hub in.
Otherwise the inner race will separate from the bearing and you will have to start over.

Once you successfully get the drive hub pressed in you can reinstall the knuckle on the car.

thanks for the info. about what i expected. I have done bearings on older cars from the 60's, but never on a mid engine late 80's car. not sure i want to use my car as a first time MK1 rear wheel bearing learning project, so I might farm this one out or at least get help from someone who has done it before successfully (Chesterky)

It's really not so bad, especially the rears. You can also still get new hubs for the rear. The worst part is getting the old inner races off of the hubs, at least it was for me.

is this the correct hub assembly below? for left rear, or do they fit both sides? just did a search for Timken and did not get too many recent reviews that were not pretty bad. is this the oem Toyota part? said rear hub when i looked it up, abut then it says front hub when you get the page there. confusing.

Yeah, looks like it. I went the cheap route and got one of those ~$30 Corolla front hubs from Rock Auto with bearing pressed on already, then had to cut a line in the race and use a chisel to knock it off. I got a separate MR2 spec bearing to use and it's held up fine so far, even with my 9" wide -15 offset wheels.

Hmmm, that is interesting that you found that front hub, I didn't think it was available. Might not actually be able to order that.

will call them monday to see what the deal is. I have had experience with Toyota where parts that were NLA show up again years later where they make another run due to demand.

called the Toyota dealer, and early 90's FWD corolla front hubs are the same parts exactly as the rear hubs on MK1's. none of the parts calculators online seem to know this.

1987-2002 Toyota Corolla Wheel Hub Assembly - Driveshaft & Axle - SKF, Front 87-02 Corolla Wheel Hub Assembly - 8001-01200764 - PartsGeek


info on SKF --OE suppliers to a lot of car companies. they have the best reviews for hubs and bearings online at the various forums.

I still have a bearing and seal kit coming from TWO's r us that I will use on the other side at some point. But there is enough play in the left rear wheel that i want to just replace the entire assembly with a new one and be done with it.

I used 93+ corolla fwd hubs when I did mine of the Fx16, the hubs from the fx are the same as those found on the rear of the mr2.

The 93+ corolla hubs are also much less expensive.

Andy are you planning to replace the hub along with the bearing?
Most times you can still use the hub unless the bearing has seized and spun on the hub shaft and tore it all up. On the other hand new parts do give good piece of mind.

Are you planning to do the install yourself or take it somewhere?

You could save cost by removing the knuckle yourself and taking it to a garage with the bearing kit and have them press it out/in.

You can buy everything you need to do the job at harbour freight and then take the tools back for a refund once you are done, that's how I went about it. I bought the shop press, bearing install kit and splitter plate and took it all back after I was done.

This is a good idea. The hub shaft fails quickly once the bearing gets loose.

Another detail to be aware of: You can pull the hub assembly with the axle still in the transmission, but if you decide to detach the outer half-shaft, be aware there is a specific alignment to mate the shafts to avoid shearing the half-shaft bolts.

Has anyone suggested finding a .PDF of the Toyota Factory Repair Manual? Google finds a few downloads.

going to replace the entire assembly now that i feel like I got a quality new complete hub to put in there. saves having to press in and out the bearings as well.

youtube has some video's to show how it is done.....it's not as difficult as you may think, but a 20 ton press makes the job go very smoothly. You could do all the prep work yourself first and just have a indy shop press the old bearing out (takes a minute or two) and then press the new bearing in (another minute or two of work) and then you finish the rest yourself.

typical first time job --lots of things went wrong today. the new hub was perfect, but the bearings in the kit were undersized for my SC HUB carrier. maybe the 89 cars had slightly larger bearings?

Had no trouble taking everything apart, but when I pressed the bearings out of the carrier, they fell apart leaving just their outer edge races, which were a bitch to remove because you can get anything to grab on them. I had to cut them with a small cut off tool and whack them with a strong punch until they came off in chunks. loads of fun. BTW, new rear hub carriers are NLA from Toyota.


luckily the OE Toyota seals and bearing arrived from David today and they fit perfect (that I had planned to use on the other side later) so I used those on this side. I know when I am beat, and with no intact old bearing to press in the new, I had my machine shop press them in and assemble the hub carrier and hub for me. got it all back together and it is so smooth and tight back there now. all is well that ends well.

Good to hear you got it all back together.

When I bought the hub kit for the 93+ corolla to do my Fx16 (same hubs and bearings as rear mr2) I discovered that the bearings with that kit were a few millimeters smaller than the ones I needed, same with the seal. The kit looked the same online and the hub was usable but the outside of the bearing was just too small.

My guess is the later model corollas came with those smaller bearings and that is what came in your kit.

I ended up using the hub from the 93+ kit and then sourced the correct bearing and seal from rock auto to get it all done.

Here are parts I used for rear bearing fix.
http://imgur.com/8vhpl3y

Spindle assembly from rockauto. The bearing, and seal kit I bought on amazon. It is the same parts as what NAPA was providing to me. Not toyota brand, but fit perfectly and hopefully will last a long time the new spindles.

I was burning out bearing every year but I believe it was due to these worn down spindles.

Also, 20 tonne press recommended. My 12 tonne didnt handle the job.
