Hub bolts are back in and now trying tap it out but little hesitant ....not sure how much beating it can take before I mess up threads on those bolts ...not exactly best access to 2 of them so hitting with equal force is not easy either

I've done both of my rears. On one side I screwed the bolts in half way and hit them with a brass punch, one the other side I used the same punch directly on the hub from behind. You have to hit quite a few times, and you have to re-position the punch after a few hits.

anyone try these? "AM-91638625"

(http://www.ebay.com/itm/Front-Wheel-Hub-Bearing-Pair-Set-for-05-11-Legacy-Outback-/311392435992?hash=item48806f7f18:g:WFkAAOSwjVVVkWsb&vxp=mtr).

 

They're supposedly a direct fit to the oem 28373AG01A wheel bearings.

 

Or these? "92-00569 AN" (pair 92-90021 2H)

nvm, found some threads talking about these. was just discussed w/o the part#s

 

 

I'm just saying...why take the risk of it not working. We know the Timkens work. They are just a few dollars more. Granted you can replace one if you have to in under 30 minutes, but why take the chance.

i got a pair of front ones from detroit axle for $67, gonna play the lottery and try em... Decided that getting those am-autoparts were probably not gonna end well.

 

Timken ones I found were at least $80 each.

derffred, thank you for posting this. I actually used your post here to help me replace my front driver HBA yesterday. Thanks a bunch.

 

TIP: Get slide hammer to pull out the HBA if it is stuck or rusted over. PB Blaster is your best friend.

Getting ready to knock this repair out this weekend (bad front driver side pretty sure). Have a friend that has a wide assortment of tools to help get this thing off. I got my torch ready if need be. Car is from N/E. New York exactly. What a pain right?

 

Question though before I order. Gonna get the Timken + nut off amazon. Should I just order two and do the passenger side too while it's fresh in my mind? I know the driver side is bad (sound goes away when I turn left) but it's gotta be dragging too right? 104 k on the car. Thanks for the help guys. This forum was a life saver when I did the timing belt in June.

At least have the other one, it will need to be replaced sooner or later.

 

PB Blaster is your best friend, let it do its job. Put anti-seize compound on all the threads going back together.

Fml. This is already turning into a pain in the ass.

 

So my damn axle is stuck in that hub. Hit it with a weak hammer chisel, nothing. Used a little two pound sledge and a chisel in the pit on the axle. Been smacking it pretty good nothing.

 

Guess I go get a slide hammer and hub puller and go to town. The video I watch on YouTube... The dude just pushed that axle back into the tranny with ease.

 

Some one lend some mind here? PB blaster soaking on a pizza break right now.

Yeah, mine was frozen solid in there too. When I did mine, it was too late to go buy a hub puller, so I had to fab something up.. I used a plate of aluminum (1/8 or 3/16" steel would have been better), drilled three holes to go over the studs (had to countersink them to have enough clearance.. argh). Then drilled and tapped a 1/2"-13 hole in the middle - bolted the plate to the hub with the three lug nuts, then threaded a long 1/2" bolt and pushed the axle out. Worked perfectly, and only took an hour and a half to make........ GRRRRR.

Just to update since I didn't see anything about it on here.

 

Ended up going to Sears and bought a 7 ton two jaw gear puller (50 bucks). Really cranked on that thing. Hit it with my propane torch for a while first. 700 degrees is the target temperature when you're doing tha stuff. Don't know if I was over or under. But it broke free. Cleaning rust up and slapping the new one on tonight..

Sorry if I overlooked the info, but what are the differences between the two different Timken numbers? :

Yesterday I did both front wheel bearings on my 2008 Legacy 2.5i. I used TIMKEN HA590315.

 

The car is my daily driver in Alberta and everything had some rust on it. On my first try I did use WD-40, 24" breaker bar and 30" cheater pipe = the breaker bar snapped. Yesterday I borrowed my neighbors impact gun, boughts 32mm impact socket at Napa and used liquid wrench penetrating oil after reading this: http://forum.miata.net/vb/archive/index.php/t-453091.html, the axle nut was down in 10s, I was so happy.

 

The hub was frozen on the knuckle. Chisel and hammer for 15 minutes fixed that. I've put anti-sieze on all mating surfaces and assembled everything back together. Torqued to spec (162lb-ft), tested on the road and works great. Noise is gone (passenger side had the bad one), cruise control works, no abs light. I am very happy with the timken bearing quality, it was made in US, looked exactly the same as the oem one and everything was tight and smooth. Rear ones will be next =)

That is actually not true. HA590315 and HA590118 are both front bearings (HA590119 is the rear one). I don't remember where I read it but the HA590118 is the older design. HA590315 has less material on the hub and more on the flange. On my 2008 (2.5i though) the OEM one looked exactly like the HA590315.

 

I just looked on rockauto.com and for GT (05 and 08) they only list HA590315 for front and HA590119 for rear. I would go with HA590315. You can always take the front wheel and rotor off and check what you have there now...

I seem to recall the flanges are different front to rear. I recall them looking like those in the picture when I replaced mine. I also remember telling the parts guy at the dealership he gave me the wrong one just by looking at it.

Yes, they are different. They differ in the hole layout, this is a picture of the rear one, HA5900119:

The holes are evenly spaced on both sides. On the front ones, on one side the holes are further apart.
