Weird axle failure - pictures too *Updated*
Posted 11 March 2004 - 04:41 PM
At least I have discovered the origin of the leak, and it's easy to fix. The stuff was dripping right on the exhaust, and made for quite a stench in the car - and even some smoke when I was at a stop light a few weeks ago.
I decided that since this axle was toast anyway, I would go ahead and dismantle the thing for a closer look into what went wrong with this "rebuilt" axle. Now I don't know for sure, but I suspect that this axle wasn't rebuilt at all - it was just repacked, and a new boot put on it looks like. You guys tell me if you think the damage in the lower photo's could have been caused by less than 10k miles of driving. I replaced this axle around September last year... If you look close in the photo, you can not only see the spalling on the bearing race, but also that the race has a cracke running the length of the valley where the ball sits.
What's the consensus? The boot was undamaged, and the grease was nice and clean - no evidence of leakage present, and yet the damage seems severe for less than 10k of driving. I didn't get a warrantee with this one, and I sure do feel ripped off.

2. lack of lube allowed the spalling as you noted
3. due to lack of lube and prolonged use, the blue marks are from over heating
4. the rough () in the middle may be due to continued lack of lube, and its normal range of operation
5. you got hosed by not buying a limited lifetime warranty rebuilt or jy unit

I think they just regreased and rebooted a failed axle, and sold it to me as "rebuilt"
I sure would like to punch that guy in the nose.

Up in Canada, I've found that the MEVOTECH brand has a part no. that includes a redesigned outer CV that is supposed to be better than OEM, and the stores (Auto Parts Plus, I think) seem to be a lot nicer to customers than NAPA was. NAPA wouldn't take an axle for core (or honor the lifetime warranty) if the cv boot was ripped. These guys would take one back if it came in a shoebox, as long as it's all there.

Unfortunately, NAPA's axles are now ARI. I can't speak to ones for Subarus, but ones we've installed for other makes have had very variable longevity. Some seem to hold up OK, others don't.

Almost every NAPA axle I've ever bought did that to me, on the inside of the DOJ. I don't think I've had a single NAPA axle last more than 20,000k (13,000mi)

I send in really, really bad core axles to our NAPA, and they've never rejected one (yet). I hope you just have a particularly bad NAPA franchise.
General: IMO, the damage shown was present when you received it. The inner race should not have passed inspection during the rebuild. I do not believe that that damage occurred in 8k miles, unless you had lubricant contamination (ie a ripped boot). CV grease is special stuff, and you don't really need a lot of it to keep the wear down, but introduce some grit and the wear rate skyrockets.
You got a bad one.

needless to say we left it there.. this was napa in ashland, or btw..
really looks to me like they repacked and booted it and gave it back to ya.. hate places that rip people off like that..

Also,the guy said he'd take whatever axle I brought in even though I'd be getting another 25T axle for Turbo manual shift.
So far my local NAPA has been great for me.Most parts I use are dealer but for axles and radiators I don't have a problem (yet) with NAPA.

This canadian company "Mevotech" that was mentioned above does indeed have a redesigned outer joint - I have emailed them to find out more, and where I might get them in the US....

Should be about the same for me - we are both about 3000 miles away from them...

Pressed in sounds right - I tried beating on one, but couldn't make it budge. They are on there with something stronger than I can remove with my neanderthal techniques. Maybe someone else on the board knows the magic words to open one up.... anyone?

Replacement parts: Cvaxles.com will sell you the individual pieces if you really want to rebuild your own. They might even tell you how to do it properly.

I'm not really sure that they are still around. The last time I did business with them was two axles for my wife's Geo Metro. They were the only ones who were able to supply them in a timely fashion (no one up here stocked them and the local price was outrageous-->$200 EACH!). They had two axles back to me in two days at $69 each plus shipping. I put both axles on the car more than three years ago and they are still working just fine.
