 I don't care how much grease you pile into those caps, there's no way in hell I'm slamming them with a hammer like that. No poo poo you'll pinch the yoke; it'll probably be the least of your problems. I had a '65 Plymouth Fury, so I got good at replacing U-joint crosses. I had a piece of bar stock cut to fit the yoke to prevent pinching when I hammered out the old ones. Never had an issue vising in the new caps...the biggest bitch was making sure they were perfectly straight before spinning them in. My finest moment was recognizing a dying cap before the driveshaft let go & changing it out on my '86 Ram conversion van, right on the shoulder of the Pennsylvania Turnpike. No matter what Chrysler product I owned, I always carried a spare cross for it. I own a Pontiac now. PainterofCrap fucked around with this message at 00:06 on Mar 9, 2013 |

... you're missing the point. The needle bearings go around the trunnion, they don't see any impact. The grease just keeps them upright so they don't fall under the end of the trunnion. And the "no poo poo you'll bend the yoke" bit - you're fundamentally misunderstanding this. Use a press or clamp wrong, or right (and have it bind a little by accident) and it WILL bend the yoke. Do the hammer method, and you'll never bend it without being a retard. I do it like this all the time and I've never bent a yoke ear. I learned this trick after doing it ONCE with a press/vise/c-clamp, bending one ear, and having the axleshaft explode and take out my balljoints the next time I went rock crawling. Painful lesson, but one well learned.

I tend to work on older cars. They're frozen up tight. I'm referring to the caps, I know what the pin bearings are and where they're located. And if you don't smack that cap dead-on on the first swing, a pin will pop loose. Press in with a vise, and the shock won't shake 'em. And yes, I lost one too, after trying the hammer method & bending the yoke, in 1979. Stuck to slow pressure after that. Using an arbor press was dreamy.

I live in the rust belt, where we just leave things out overnight to rust solid instead of using loctite  I've seen quarter inch steel plate brackets on axle housings rot in half and heavy truck frames crumble.I guess I'll have to agree to disagree, because I've seen people bend axleshafts in a vise and I've done it myself, yet I've literally never bounced a needle bearing out while using the hammer method, having done more u-joints that way than I can count. You don't just put the cap in place and slam on it, you have to hold the trunnion up into the cap from inside the yoke while tapping the cap in, then once that one's seated and has the retainer clip in place, flip it over, hold the trunnion up to "split the difference" between the two opposing ears, get the bearings started over the end of it, then tap it in place too. Works every single time unless you are all thumbs. I'll have to do a full video of it sometime... that video I linked is someone else's and he only covers a little of the process.

Following a recent snow storm, a late 90's Grand Marquis comes in on a tow truck. The owner claims his 17-year old son slid it into a curb and "something underneath broke" Musta been some curb...       I didn't get a chance to get a picture of it; but when the core support buckled it smashed the fan shroud into the fan blade to the point where it won't spin at all. It barely ran when I started it and quick scan of the ECM revealed that it had overheated and went into "cylinder head protect mode". I'm guessing due to the weather he left it running for heat while he waited for help. Whoops.

I've seen people with their vehicles left more off the road than on because they hit a curb so hard. I've seen one high centered on a decorative boulder this way My biggest fear when winter driving is hitting a curb while trying to make a turn, ie with the wheels turned. Also, if you've never done it, mucking around in curb lanes or parking lots that haven't been cleared sometimes makes a vehicle jump what feels like a foot to the side. It's fun in a Laser, it's quite a ride in a minivan. And since winter driving has been on my mind this week, I had the fun of trying to pull into a free flow lane only to discover that not only had no one cleared the free flow lane but had pushed the snow from the 3 other lanes into it. And there was a Semi in the lane next to me. That was embarasing.

Here's an update on my mechanical failure from earlier in the thread. I got my car back from the dealer yesterday. The new engine was completely covered by warranty. What concerns me at this point is that it drives better than it did the day I bought it, which makes me really wish I had had it inspected before buying it. But all's well that ends well and I have a decent city-car again. I did like the 2013 loaner they gave me. It's as far ahead of my current Elantra as mine is from the previous generation. Leather, sunroof, satnav, and heated seats. Don't let anyone tell you you won't need heated seats in Florida...

My one success with an ez out was on the screws holding on the top of my brake master cylinder on my KLR-650, but those screws are as soft as aged cheddar cheese.

Just gonna cross post these pics... Jeep Dana 30 carrier bearing. Near as I can tell, an axleshaft exploded inside the diff, wallowed out the inside of the carrier bearing journal, probably thermally and mechanically stressed it to the point that it shrank away from the bearing cone when it cooled, then the bearing spun against the setup shim stack. Where's my carrier bearing? Where are my shims? Why are there marks on the inside of my carrier bore? What is happening to me?   Shims (well, the only shim that wasn't turned into a pile of metallic flakes) and carrier bearing journal are in great shape.  Highly polished carrier bearing bore.  So I put it back on.  And then I slid it back off again!  https://www.youtube.com/watch?v=OqBm07pl3A0 In all the diffs I have torn down, scrapped, and replaced parts in, I have never seen a carrier bearing spin like that.

Sir Cornelius posted:That conical bearing shows every evidence of "False Brinelling". My best guess is that someone neglected torque-wrench calibration. Probably some alignment issues too. The whole thing gets installed into a cast steel differential housing with the caps held on by two giant bolts each. Those cones are pressed onto the cast steel differential ring gear carrier you see in the pics - which part is false brinelled? The inside is simply spun from carrier damage from what I can tell, all the marks are concentric rings mixed with larger scars from debris balling up and chip-welding, I didn't even look at the roller bearings themselves as they appeared fine on the surface, unlike the inside of the cone and the mating surface it was on. Those bearings are supposed to be a tight interference fit - most people install them either using heat/cold thermal expansion tricks or with a multi ton H-frame press. The shim I showed SHOULD have been completely untouched - the way it's damaged indicates to me that it acted as a bearing surface for the cone to rotate on the diff carrier, in normal operation the cone and diff carrier would be a tight interference fit and the shim would see only compression forces.

Sir Cornelius posted:No way!! Seriously, this has to stop! Witchcraft! To be honest, it took 8 hours to get that bolt out, with multiple failures and 3 destroyed drill bits trying to carved out a spot for the EZ-Out to get at. I was about to give up when I finally heard the noticeable pop of a bolt coming un-torqued.
