PhilT Posted January 2, 2009 Share Posted January 2, 2009 You don't have to have an alignment done after replacing any of the hub assemblies right? No, nothing will have changed, or should have changed. Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...
PeterJMC Posted January 2, 2009 Share Posted January 2, 2009 Question about diagnosing which wheel bearing has failed. Listening while the car is in motion is a little difficult. I have a hum but I'm having a hard time finding out where it's coming from. If I have no access to a lift or rollers, how can I tell which corner its coming from? Seems like I would probably have to just take it to a shop to diagnose? Link to comment Share on other sites More sharing options...
PhilT Posted January 2, 2009 Share Posted January 2, 2009 I changed the front bearing yesterday, a few pics during the work: Wheel removed http://i39.photobucket.com/albums/e194/PhilTGT/Wheel%20bearing/DSC00843.jpg Brake caliper removed http://i39.photobucket.com/albums/e194/PhilTGT/Wheel%20bearing/DSC00845.jpg Brake disc removed http://i39.photobucket.com/albums/e194/PhilTGT/Wheel%20bearing/DSC00846.jpg Using a "slammer" to pull the hub out http://i39.photobucket.com/albums/e194/PhilTGT/Wheel%20bearing/DSC00847.jpg Hub removed revealing the spline http://i39.photobucket.com/albums/e194/PhilTGT/Wheel%20bearing/DSC00848.jpg New hub vs old hub, notice the change in design http://i39.photobucket.com/albums/e194/PhilTGT/Wheel%20bearing/DSC00849.jpg New hub installed http://i39.photobucket.com/albums/e194/PhilTGT/Wheel%20bearing/DSC00850.jpg It is a pretty simple job, but the hub bolts were badly rusted and took alot of hammering to get them out, otherwise not hard at all.

Seems like I would probably have to just take it to a shop to diagnose? The only certain way is to put the car on a lift and then run it in the air. Listen with a screwdriver against each hub to see which one is loudest. Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...
jholder Posted January 24, 2009 Share Posted January 24, 2009 Is there any major difference for the process of replacing the rear wheel bearings vs. the front? I haven't seen any walkthroughs for the rears, but I assume it will be pretty similar. Just got done disassembling my passenger rear hub. I was 87.4% sure that was the faulty one... ass soon as I got it off of the axle and turned it by hand, I knew I had found the culprit. It feels like they lubricated it with sand impregnated oil I just wanted to chime in and answer my own question. Removal of the rear wheel bearing is identical in process to the front. I only came across two minor differences. One is that the rear caliper bracket is held on by two 14mm bolts, rather than 17mm the fronts use. (makes sense when the front brakes handle the majority of the braking load). Two, (I believe) the backing plate mentioned is integrated into the parking/emergency braking mechanism. It comes off easily as soon as the wheel bearing assembly is removed. (by easily i mean falls right the **&@#$ off) to the OP great post. It took about 40 minutes for dissassembly with hand tools and a floor jack. Most of the time was spend trying to see/find the bolts behind everything. A list would have have halved this. I'm guessing about 1:15 per wheel bearing with normal hand tools. Link to comment Share on other sites More sharing options...
overl0ad Posted January 25, 2009 Share Posted January 25, 2009 random qsn: could we potentially replace the hub with an STi one to go to 114.3 PCD? i'm at the point where i need to get mine done, but i'm guessing that subaru will not do it under warranty as i've got coil overs and a whole bunch of other stuff as far as handling goes...

That depends on your dealer. My rear ones were done under warranty, but I have a good relationship with them, and had a lot of work done there in the past which I have paid for.

legacy_y_tu Posted March 7, 2009 Share Posted March 7, 2009 Anyone have a picture of this backing plate? I'm pretty sure I've got a bad bearing up front somewhere and am getting ready to replace it. Just want to make sure I know what I'm doing before jumping in. Sounds like a real basic job. Also want to do this when I'm swapping in my new DBA rotors since the old ones will be off.

Correct, and a spray can of penetrant as they are usually rusted to hell. You can resue the axle nut, but it's not recommended.

absolutsnwbrdr Posted May 10, 2009 Share Posted May 10, 2009 I mentioned to my dad that I was planning on replacing my front right wheel bearing and went over this walk through with him. The only question that he brought up is if there are any torque specs on the 32mm nut. Anyone know? Link to comment Share on other sites More sharing options...

absolutsnwbrdr Posted May 11, 2009 Share Posted May 11, 2009 Just called 2 dealers today to get some prices on the hub assembly and axle nut... got an interesting answer from the first... In York - "This does not come as one unit" Hub Housing (not complete) - $143.00 :eek: Bearing - $87.40 :eek: Seal - $10 Seal - $12 Axle Nut - $4.00 Total = $256.40 + tax :eek: :eek: In Hanover - "Sure we have that in stock! But you won't need a new axle nut" Hub Assemble (Complete) - $127.00 Axel Nut - $3.60 Total = $127 + tax Just thought I'd share Link to comment Share on other sites More sharing options...
naimouasta Posted May 18, 2009 Share Posted May 18, 2009 maybe it was an error? Link to comment Share on other sites More sharing options...
absolutsnwbrdr Posted May 18, 2009 Share Posted May 18, 2009 I called the York dealer back and questioned the parts guy... he insisted that the front wheel bearing was not available as a complete assembly, and that the part number I have for the complete assembly is for the rear. Well the part number I gave him was the same number that the OP has pictured, and it matches what the Hanover dealer gave me. Link to comment Share on other sites More sharing options...
BLACKonBLACK Limited Posted May 19, 2009 Share Posted May 19, 2009 i think i have at least one wheel bearing that needs replacement Link to comment Share on other sites More sharing options...
sw686blue Posted August 21, 2009 Share Posted August 21, 2009 Let me subscribe to this thread because I'll be changing my front bearing very soon I suspect! Great job guys! Link to comment Share on other sites More sharing options...
cryo Posted August 23, 2009 Share Posted August 23, 2009 So just to clarify the dealer will replace the rear bearing up to 100k on 05-06 legacy/outback but are the fronts only covered under 36k or 50k warranty? thanks in advance Dave [sIGPIC][/sIGPIC] Providing unmatched customer service and a Premium level of Dyno/E-tuning to the Community cryotuneperformance@yahoo.com facebook.com/cryotuneperformance.

msb175 Posted September 8, 2009 Share Posted September 8, 2009 argh. i've had a humming noise coming from the front right of my car for a few months now. Thought it was the tires, but after a rotation, still. i guess it's the wheel bearing. Another thing to add to the list. Link to comment Share on other sites More sharing options...
nka Posted October 15, 2009 Share Posted October 15, 2009 On the PDF WARNING: Remove the wheel before loosening the axle nut. Failure to follow this rule may damage the wheel bearings. Would be very sad to damage a damaged bearing your about to trash! Link to comment Share on other sites More sharing options...
2006Specb122 Posted April 16, 2010 Share Posted April 16, 2010 These should be covered under the basic warranty or even the 100k extended warranty and should not be void because of minor modifications? Is there any scheduled maintenance for the bearing or hub assembly on the LGT? Some cars as you to repack hubs with grease after certain miles. I've never seen anything for the subaru. Also, how many miles do we expect to get from the bearings? Link to comment Share on other sites More sharing options...
MeoW71 Posted April 19, 2010 Share Posted April 19, 2010 (edited) There is no scheduled maintenance on the wheel bearings. Both the front and rear ones are sold as a single bolt on item. You can not order the parts separately. As for miles. Really depends on how much you are abusing it. Driving around normally? probably a long time. Autocross/track/silly stuff on winding roads, not as long. At least it is super easy to change them out, unlike a WRX. FYI for those who wanted to try the 5x114 ones, the STi ones will likely bolt up, but you will lose your ABS as the STi has a tone wheel, while the legacy has a magnetic pickup built into the hub assembly. Plus, the rear bolt on one is different from the front. In either case, the Tribeca ones could possibly work, but as far as I know, nobody has tried it out yet. I might in the future, haven't decided yet. Edited April 19, 2010 by MeoW71 Link to comment Share on other sites More sharing options...
