While taking off snow tires on my 2005 OBW 2.5i, I found that both left and right front control arms have tears in the rear bushing. Not very happy!

Can you tell me the TSB reference? Anyone else see this problem? This car has 62,000 miles of mostly highway driving, and has never been "off-road" (and only rarely off pavement). The only recent challenge was driving around Colorado in temperatures as low as -20F. Both bushing tears look recent, but if the rubber is not designed for those cold conditions, Subaru needs to include a marketing disclaimer.

I will probably get to the dealer for a discussion this week.

I've got a tear, too, and some questions about brakes and oil filters too.

2006 OBW, 2.5 sohc, 17000 miles.

First, the control arm tear. The tear is on the left side (haven't checked the right side yet). Regarding the theory about cold weather being a factor, I live in Southern California and have gone up to the snow just 3 times since I've had the Outback. Also, I don't think that the weather was especially cold during any of those snow trips. On the other hand, here in SoCal we have a lot of Ozone and it loves to eat rubber. I have posted a picture of the tear at: http://www.killthegoose.com/JointTear.jpg

I noticed the tear because I had the tire off to try to track down the source of a couple noises/vibrations I've heard recently. The vibration was a judder occurring on moderately hard braking from low speeds, like 25 mph. I don't have a lot of experience with abs brake systems, but it was almost like the abs system was cycling. Except that the tire was no where near skidding at the times it would do it. That juddering went on for a couple months, intermittently.

The other noise I just noticed in the last few days. A continuous, quiet, squeak. I could only hear it if I was driving slowly next to a wall that would reflect the noise back to me. My brake pads are down to about 3/16" of material left. Could that be the source of the squeak? (Any reccs as to what brand of replacement pads to use?)

I guess I will have to take it in to the dealer to have the torn rubber joints replaced. This will be its first visit to any mechanic - I've been doing the oil changes, etc., myself. I have a question about that too. I've been using oil filter Purolator 14410 and notice that all the catalogs now list 14610, which is TINY. Every other brand also lists the tiny filter. Would be big (old) one be preferable, if I can get it?

VF, your tear looks exactly what I have on both sides. To me this is a design or manufacturing problem. Let us know what your dealer says. Is your car still under warranty?

Well, I finally got the dealership (West Houston Subaru) to look at the bushings. With the car on a lift, both bushings show small but clear tears from underneath (just like I saw previously from above with the wheels off).

The chief mechanic claims he saw a technical memo from Subaru stating that these tears are not a problem. The service manager searched the system for a TSB but could not find one. He promised to call Subaru and get back to me. If I hear anything I will post again.

Here's the email from West Houston Subaru about the front control arm bushings:

Hi Bob,
Here is the information that I found about the Lower Control Arm Bushings.
Hope this helps.
Derrick


2005 - 2006 Legacy Front Lower Control Arm Bushings:

Dealers have reported, and in some cases replaced, the Front Lower Control
Arms for cracked bushings. Generally, replacement is not necessary. Even
with cracks up to 15mm across the outside surface, and all the way through
the bushing from one side to the other, the bushing performance is still 20
times the strength of specification.

This type of bushing works with compressed rubber and when the control arm
travels through its full stroke it stretches a small portion of the
bushing and will exhibit a crack or split. This does not affect the performance
of the bushing and will not continue to spread to the rest of the bushing.
It does not cause body vibrations, noises, or braking issues.

OK...just a heads up to all. I was changing brake fluid on my 2005 2.5i and noticed that both my lower control arms aft bushing are cracked half way. This is on the front wheels. This is not rubber just showing small tears but it is completely separated. I read all the posts above and how this should be ok, but to me it makes no sense. I will get mine replaced or will raise **** at the dealer. Since it is warranty they might say it is ok....but there is a post somewhere (do a search.. ) where a dealer saw the damage to the bushings on a non warranty car, and.....(drum roll...) said it has to be replaced!! FUnny how that works.

Had my 05 XT in for inspection, and Dealer informs me that both Lower Control Arm bushings are torn, failing inspection.

Without alot of options, had them replaced. 50K miles, 80% highway. WTF?

$12 for each bushing, and $250 labor, again WTF, killing me.
4 wheel alignment (required) totalling out at $390.

Freaking rip off
