Subaru Legacy/Outback Wheel bearing failure

    My 2003 Baja makes a loud popping or chunking noise whenever I turn hard at low speeds (e.g. pulling out of a parking space). Had both CV axles replaced...not the problem. This happens when turning either right or left...any ideas?
    [Manual transmission...vehicle excellent other than above problem.]

    If the CV joints made no difference, it is likely a differential. Can you tell the approximate location of the noise? I suspect either a front or center differential, neither of which are cheap to fix. Basically, the sound is caused by binding in the differential that is not properly released. If you try turning sharply on a heavily graveled surface, you should be able to see one or more wheels spin out on the gravel to release the pressure rather than getting the clunk/pop noises. Or, you might get both, but with the clunk/pop less frequent and/or severe.

    Also check the wheel bearings. They'd be under stress at full steering lock.

    Thought I'd add my two cents:

    While I was getting my car serviced last week, I overheard another customer and the service representative talking about Legacy (and Outback since they're essentially the same chassis) having complimentary extended maintenance on the wheel bearings because of a TSB or something along these lines that surfaced. So, the customer was happy because he got it replaced free of charge.

    As for a clunking sound, I don't have a lot of experience with AWD vehicles as this is my first, but I know that when a family member's previous car made a high pitched squeal when the power steering fluid went low. I suppose as the car warmed up and the fluid expanded (via thermal expansion) it covered more of the parts, which is why it went away after the car warmed up. A later inspection showed that the power steering reservoir/hoses had a leak so they were replaced and the problem was fixed. Could be worth checking out.

    I have a 2000 Outback Sport Impreza and I seem to be having the same problems. My car only has 71,000 on it, but I have gone through 3 bearings, just this year. Did you get any answers on why this is happening or how it can't be prevented? Thanks!

    My 2003 Baja (manual trans), at approx 85,000 miles, sustained a failure of the viscous clutch (at the center diff)...transmission was fine...NOT wheel bearings, but was told nevertheless that this should not happen with so few miles on vehicle.

    Symptoms were chunking noise when turning steering wheel hard (as in parking), particularly after vehicle had warmed up thoroughly.

    I think in 2002 the Impreza switched to sealed-type bearings.

    For yours, I believe the fix is to have Legacy bearings installed, which are a bit heavier duty.

    In addition, if the spindle was damaged by the failure of a previous unit but was not replaced, any subsequent bearing installed on it will be more prone to failure.

    Just posting to report an Outback wheelbearing failure - @58K miles on my 2005 OBXT Ltd - replaced by dealer at no charge under extended warranty.

    Glad to hear they covered it for you.
  • Dude, your Viscous Coupler is shot.

    It went on my 2004 Outback at 100k.
  • I bought my first Subaru in 2006. Never another! At 90K both rear wheel bearings fail, then a few weeks later the right inner cv joint boot fails (the boot is 2 inches above the catalytic converter). I called Subaru customer service regarding the wheel bearings. They extended the warranty on some 2006 Outbacks to 100k, but not mine. What not ? The wheel bearings were crap on mine too. Subaru would do nothing for me.

    I have a Honda with 285K on it, never had a bearing or drivetrain problem. I also have an Isuzu SUV with 140k, no major drivetrain issues.

    I was told that Subaru's were great, as long as you sold them before 100K because they self destruct. Now I know how good that advice was.
  • Own a 07 Outback and have replaced three wheel bearings. First at approx 58k, next at 65k and last at 79k. First under basic warranty. Second fixed by Subaru after I contacted their "customer Service." The third bearing they reimbursed me for only after writing a scathing letter to Subaru. Their reply basically stated that we will pay for the third bearing, but don't ask for any more help.
    Three wheel bearings in a vehicle with under 100k. Sounds like poor design or a bad batch of bearings. Neither of which Subaru will admit to! Like the previous post I think I'm done with Subaru. I live in upstate NY and drive in snow for 4 months and the vehicle excels at winter driving. Unfortunately I'm furious with the Subaru local dealer and their "customer service department" and will probably never purchase another Subaru again and will tell as many potential customers as I can!

    You have some tough standards. By 90k miles my neighbor's Dodge Grand Caravan was on its 3rd transmission. And that's a lot bigger than a wheel bearing! :sick:

    Best of luck to you, but I really think you were simply lucky with that Honda and Isuzu.

    My 08 OB is about to have its third wheel bearing replaced ( two in front and one in rear) with less then 58k on the vehicle. All have been replaced by Subaru at no cost. However my concern is that this will be a continuing problem. A friend bought the same type of vehicle the same day from the same dealer and he has had the same problem. Whats going on? I live in the mountains with salty road conditions. Could this be adding to the problem?

    Thought or opinions welcome.

    Having owned a few Isuzus in my day. They are very tough vehicles but really well built cars like them are few and far between. GM killed off Isuzu, so that's not an option.

    As for your standards, well they are pretty high. There were some issues with 05-06 Legacies and Outback bearings, bad batch. They extended the warranties to 100k miles on them.

    As for the axle boot going on a turbo car, this is fairly common on modified Outbacks/Legacies due to their proximity to the downpipe from the turbo. The stock ones have shielding to protect them but aftermarket ones don't.

    The salt could definitely part of your issue. Not much you can do about it other than to find a good local mechanic. It's about a $200 repair at an independent shop. (1 hr labor and about $125 for the part).

    I have a 2005 Legacy Wagon w/ 113000 miles. To date I've had no issues (I'm knocking on all the wood I can find) but I've noticed the interior noise is getting louder and louder. The tires have plenty of tread and have been rotated and the brakes are OK, could it be the wheel bearings? I live in Northern Virginia on a dirt road so there is some salt and plenty of dust.

    Also I just took it to a local shop (who I THINK I trust) for the 100,000 maintenance and they suggested replacing the water pump. Including changing all fluids and belts, etc. it was about $1200 which included 10 hours of labor at $70/per. Previous 30,000 and 60,000 maintenances were in the 300 range so I thought this was a bit high.

    Any suggestions? At $700 for labor I may try doing it myself...

    Thanks, and yea I'm new.

    If the noise varies with speed, and feels like a vibration, and if you notice a marginal decrease in power/speed, it could be bearings. Mine went like that and it turned out to be only the front bearings. $700 to fix and it was like new.

    I had bad bearings on a Mazda 626 and noticed the same thing - pitch was speed-dependent.
