Hi
I'm going to replace my front wheel bearings, and I have a couple of questions:
1. I see that there are 2 bearings in each of the front steering knuckles, are the both the same sizes?
2. Are there any tricks that I need to know when it comes to getting the d bearings out?
Thanks

Gen 1 or 2?
I know the gen 2's are both the same along with the bearing in the stub shaft. the seals are different inner and outer.
Someone more gen 1 savy would have to help you with those.
Replacement is easy and straight forward, especially with access to a press. Remove seals, press/pound out bearings, clean, grease and put it back together.

Pretty much what indkid87 said. The Gen 1's are the same bearing on both sides. I usually do this kind of bearing on the car with a brass punch, but it's even easier if you remove the knuckle.
Mostly you just need to know that during install you only apply force to the outer metal edge of the bearing. You can use a bearing adapter and press, a brass punch, giant metal washers, etc, just make sure you only apply force on the outer edge. With a punch you just do taps back a forth on either side of the bearing, working your way around the whole circumference. There might be a spacer in between the bearings, make sure you keep that and re-install it.
Do not use a steel punch even when you are removing the old bearings.
If it's brutally cold where you are working on the car, the knuckle might contract quite a bit and may fight you trying to install the new bearings. I usually put my bearings in the freezer overnight before a bearing job. You might have to heat the knuckle to get it to open up a bit if you can't get the bearing started.
And don't over pack your bearings. There is a lot of info about packing bearings on the net, so check there if you are unsure.

And don't loose track of the spacer between the bearings! Otherwise when you torque it down you will overload the bearings themselves. I once opened up a front end with no spacer, not sure how long it had been like that, but the bearings were shot, as in grenaded shot.

Alright thanks guys
One other question: can both the bearings be pulled out one side, or must the inner be pushed out the back, and the out pulled out the front?

Alright thanks guys One other question: can both the bearings be pulled out one side, or must the inner be pushed out the back, and the out pulled out the front? They cannot be pulled out one side. There are bearing seats inside the knuckle, which is essentially just a smaller diameter bore in the center of the knuckle. When you install the new bearings you want them to be fully seated in the knuckle, meaning they are pressed or tapped in completely until the outer metal edge of the bearing is installed tight against the seat.

i learned something when doing this job on my 89. did you know that when you are looking at an exploded view and a bearing is shown on the "left" side of the housing thats the direction it comes out? and vice versa? i had no idea that is how they were drawn.
anyways….the bearings come out towards their respective sides. there should be a shoulder in the middle preventing you from pressing them in too far but it also keeps you from taking the bearings out the "wrong" direction.

Rebuilt the whole front end on my 94 Justy Dl. With the excellent info on this post saw no need to start a new one. I had no way to get to a press so I used a steering wheel puller modified with a washer, the same size as the outer diameter of the bearing, and a hardened nut that would not strip! I had a choice of two styles of bearings. One I would have to pack, the other sealed. After knocking out the old bearings and seals, I used my modified steering wheel puller to install the bearings. Lightly lubricate the bearing race so that the bearing will slide in as it is being tightened. I used a 1/2' rachet and socket to pull the bearings to their seats. A 3/8" rachet would be too small. As madmatt said, make sure you reinstall the spacer before installing the final bearing. Hope this helps!

This is a great thread for all of us that have to replace the wheel bearings. I just thought that I would put this diagram here, to give everyone an overview of the entire thing. moemoney313 if you could please list the part numbers of the seals and the bearings that you used, that would make it easier for others to copy your excellent work!

FRONT BEARINGS BECK/ARNLEY 051-3442 YOU NEED FOUR, TWO PER SIDE. OUTER GREASE SEAL TIMKEN 224462 YOU NEED TWO, ONE PER SIDE. INNER GREASE SEAL TIMKEN 1974 YOU NEED TWO, ONE PER SIDE. CAUTION: DO NOT PUT THE SEALED BEARINGS IN DRY! USE WHEEL BEARING GREASE TO LUBE THE CENTER SPACER AND COAT THE OUTSIDE OF THE BEARINGS. THIS ADDITIONAL GREASE WILL HELP TO TRANSFER HEAT TO THE BEARING HOUSING AND PROVIDE LUBE FOR YOUR SEALS. DO NOT OVER PACK!

Neat, I didn't realize there was a sealed version of that bearing. That might work nice for rebuilding the jack shaft. I know the bearing in there is the same size as the front wheel bearing, but I don't think you can get the proper seals for it.

reviving this...
can anyone confirm what front bearings a 89 4wd 5spd takes? either by a part number or dimensions? or are they the same for the front end regardless of 2wd vs 4wd?

so theres record of this...
Timken, a prominent bearing and seal manufacturer does not make a distinction between front wheel bearings, inner vs. outer or 4wd vs 2wd models. The front takes two of the same bearing regardless of 4wd or 2wd in the 89 and later.
they do however list two different seals, one inner and outer for the front.
