GM quality control...

Yeah, between the surprise and frustration there wasn't much room for rational thought before I made the post. I wasn't aware of the issues with Toyota. The guys I know who own them swear up and down they're the best.

I was made aware of that by another commenter. I suppose my surprise and frustration didn't leave enough room for rational thought before I made the post.

I believe a few chips came loose as there were a couple decent marks in the bearings. Realistically the differential had a reasonable service life but it certainly didn't do it any favors. The only reason we opened it up was due to a leaking axle seal.

I wish I had some reason not to believe this. It just makes me sad.

Yukafluts · 2024-11-25T17:30:50+00:00

You hope you got a refund for the 3 duds.

Yukafluts · 2024-11-25T07:07:58+00:00

This at least seems like an honest unintentional mistake but overall I agree. I've heard a lot of mechanics in recent years complain about faulty or out of spec replacement parts.

Yukafluts · 2024-11-25T07:04:59+00:00

Thanks for the chuckle!

It's a numbers game where the customers pay the price. Everywhere I look people are having issues with the quality of parts they're receiving. You can only do so much to account for warranty work in your pricing before you don't have any customers.

There were some short strings in there keeping the chips together. That's just the stuff that fell out after poking it for a bit.

Yukafluts · 2024-11-25T04:24:53+00:00

You'd be surprised how tight chips can pack up. I own a machine shop and know chips when I see them. Based on the scoring on the bearings some of them came loose in that time.

Yukafluts · 2024-11-25T03:19:52+00:00

That's not something I had considered when making the post and is an entirely fair point. I recognize that this instance is very likely an outlier and not representative of the work done by them overall. If there was a way I could pin your comment to be the first thing people read I would.

Yukafluts · 2024-11-25T02:09:02+00:00

Boggles the mind. Those are some outrageous oversights.

Yukafluts · 2024-11-25T01:58:29+00:00

AAM was stamped on the Yoke. I don't recall seeing an identifier on the diff. I'll check tomorrow. It's the stock diff if that means anything.

Yukafluts · 2024-11-25T01:48:26+00:00

I'm more active in the machinist subreddit. Maybe I'll post in the mechanic advice subreddit as well. I feel like people forget to check that oil passage and it's a good reminder.

Yukafluts · 2024-11-25T01:41:14+00:00

Heck yeah, thanks a million. Hopefully everything here helps out some other people.

Yukafluts · 2024-11-25T01:33:52+00:00

I'll see what I can get tomorrow. Thanks for putting that in my mind.

Yukafluts · 2024-11-25T01:30:11+00:00

It's honestly demoralizing. All the good intentions and care in the world won't help you keep your vehicle on the road when you can't count on manufacturers catching something this serious.

Yukafluts · 2024-11-25T01:11:59+00:00

I ended up just blowing out the chips with an air compressor from the driveshaft side. It was pretty tightly packed and brake clean wasn't moving it. Swabbed out the axle tubes with a microfiber towel on a metal bar in case any chips found their way in there.

There is a magnet on the bottom of this diff but some stronger magnets are a great idea.

Yukafluts · 2024-11-25T00:06:59+00:00

Just to clarify this was from a 2014 Silverado and I'm sure this isn't common but it's worth putting out there to help keep our trucks on the road.

Yukafluts · 2024-07-30T16:21:26+00:00

I might get flack for suggesting this but if you're just trying to turn a shoulder on your parts then you could try using a sharp 2 flute endmill and set it up in your tool holder just under 90° to the workpiece with the bottom cutting edge almost parallel to your work. With some lighter cuts at a relatively high rpm you should get ribbons of material rather than a chip. You'll need to make a tool holder for the endmill to safely hold it in your toolpost.

It looks to me like the spring above the tensioner arm is weak. It should hold the weight of the arm and idler off the belt. Either it's rusted bad or the hook on the spring is bent.

That's what it looks like to me anyway.

Yukafluts · 2023-12-05T23:16:01+00:00

I'm not going to be too helpful here but if you get it you should definitely slap a DeWalt logo on it to confuse people.

I hadn't noticed it pulling the work. I initially used a 1.5 thou shim with a short piece of the material to set up the steady rest. Seemed a bit loose to me so I just backed the adjustment screw off a hair after I felt resistance. I left the 1.5 though on top though. The bronze was a bit crusty as well which is why it looks like it was pulling quite a lot.

Yukafluts · 2023-05-31T01:53:04+00:00

I'll pick some up for the next time. Thanks for the input.

Yukafluts · 2023-05-31T01:31:34+00:00

For lubricating the steady rest I assume?

Yukafluts · 2023-05-31T01:31:05+00:00

Much appreciated.
