A couple of weeks ago, I placed the replacement front axle for my 2017 2.5 Outback in the shopping cart, at the website of one of the on-line Subaru dealers. The part number for my VIN number was 28321AL000 ($293++)

Today I completed the purchase, just to get an email from the dealership, indicating that the part number was no longer the right one, and instead the 28321AL010 was suggested ($331++). This part number was previously indicated for the H6 model.

I guess Subaru realized how bad the original NTN USA CV Joint was. To start with, the outer CV Joint is not available by itself, it comes with the axle, with or without the inner joint.

When I took the old outer CV Joint boot off, I found out that the CVJ comes lubricated with heavy oil and not grease, which has been the norm in every other CVJ that I dealt with in the past. I also found the oil to be loaded with metal shavings, explaining the loud and scary noises coming out of it. I also noticed that the CV Joint bell was not as deep as they used to be, allowing the ball bearings to get out of the bell groves when turning. In the older CV joints this would not happen, and the only way to make the ball bearings come out of the bell groves was by removing the axle from the joint.

This 2017 is my 3rd Subaru, and I got all of them brand new. The 2017 is by far the most unreliable of the three. I like the car, alot, but 4 NTN USA wheel bearings hubs failed, (one of them a genuine replacement to a failed original one), 1 front axle (NTN USA), and one broken rear trailing link (arm) is beyond the pale, for a car with no off-roading, not even a gravel road drive, and with 85K miles on the odometer. Shame on Subaru, and shame on me.

I am in south FL, so no need for salt on the roads. The trailing arm failed in 2020. What surprised me was that the dealer had the replacement part in stock, and replaced it for me within 30 minutes, no charge, and after 60K miles. For sure Subaru knows about this. At the time, the part listed for $40 and change. Now the part lists for $86.

In the first picture, you can see the beginning of a second crack on the upper edge of the broken trailing arm.

These blue ones are adjustable and use a rod end at the front for less deflection.

I've seen really rusted trailing arms but these arms look to be in great condition except for where they cracked apart seemingly from stress or fatigue. Wonder if anyone else has seen this failure mode?

Very nice setup you have there. Those trailing arms gotta be so much better than the original parts.

By the way, after I purchased the front axle a few days ago :mad:, I get an email from subarudirectwholesale offering 35% off, site wide. Maybe someone in here can take advantage of this offer.

seems like you have to play a game with purchases now days; buy a small item, wait for the coupon or promo code, then buy the big ticket items.
Inspected my 14 oem arms and they are fine, but that metal is thin.

That thin metal keeps the rear tires in position against the momentum of the car, when the parking brake is used to stop the moving car.
