Let\'s play name this part???

I just swapped out another driveshaft on my k5 (208 case to 10 bolt axle)and noticed that where the bottom of the driveshaft u-joint bolts into the rear is loose .I can take this cradle piece and move it 1/2 inch side to side and the pinion nut stays in place ..What is this piece called?? It is the part that the u-joint is held in with u straps and 4 bolts ..Thanks in advance

Bingo. Give that man a prize. That is the pinion yoke. If it moves and the pinion does not, then either your pinion nut has come loose (very difficult to do) or the yoke is shot. Never heard of one that loose before.

If the yoke AND the pinion move, then you have a shot pinion bearing inside the diff. Call Randy's Ring & Pinion. They can help you out and get you all set back up again. Hope all that helps!

How do you think my rear 10 bolt failed?
 
Re: Let\'s play name this part???

Ok thanks ..How do I get this nut out?? Is it a reverse thread or do I have to impact it out?? I never changed one of these before??the nut stays in place while the pinion yoke moves freely from side to side .?????Can I reuse the same nut once I pull it out?? Thanks again for the help
 
Re: Let\'s play name this part???

a home made holder works for me. piece of 1/4 plate with 4 holes drilled in it and a large hole for the socket in the center. And a 3/4 square hole for a socket wrench handle to attach (a 1/2 drive might work). I have used a large pipe wrench also, to hold the yoke still.
 
Re: Let\'s play name this part???

I wouldn't say it's difficult for the pinion nut to come loose on a 10-bolt. I think it happens all the time. It's usually obvious from the death growl the axle gixes off under coast.
 
Re: Let\'s play name this part???

That'd be a yoke. About $50 from the local auto parts store.

To replace it, mark your current pinion nut and pinion shaft with a prick punch. Then count threads and write it down. I just stick a block of wood under the tire and use a long breaker bar to remove pinion nuts.

When you get the yoke off measure it to make sure it's the same thickness (the sandwiched part) as your old one. This makes sure that you can put the pinion nut on to the same spot without having to use an indicator to measure preload. Inspect the splines on the pinion shaft as well, you might find that that is where most of the wear is. This is a good time to replace the pinion seal.

What about the crush sleeve? The same thing happened to my Suburban, and I was told that there's a torque spec for the pinion nut. Repair manuals tell you to use a torque angle gauge on the old nut, and then replace the crush sleeve and tighten the new nut to the same torque angle. That's great, as long as the stupid nut didn't back off, leaving you with no reference point..... /forums/images/graemlins/crazy.gif

BTW, I bought a few crush sleeves off ebay a while back for cheap. They're original GM. If you end up needing one, give me a shout and I'll mail it off to you. /forums/images/graemlins/thumb.gif

I believe it's 15 inlbs. I always end up going past the marks I made by a little bit and go by "feel" as to what 15 inlbs is. I haven't had a differential whine yet and I've swapped gears between axles and carriers between axles. Maybe I just get lucky, maybe gears aren't the rocket science everyone claims they are.

The only place I was able to find them was NAPA, and the dealer. Both places needed to order them, but it only takes a day to get in.

If this is a 10 bolt, I have four crush sleeves, I'll only ever need one or two. Email me your addy at [email protected] and I'll mail one out to you. You're only in CT so it should take a day or so to get there. /forums/images/graemlins/thumb.gif

Thanks for the tip. I think it's a combination of lucky and lack of rocket science. When mine came loose, and I couldn't find a crush sleeve, or the tq spec, I just snugged it up and said screw it. That was about 5k miles ago, and there's no howling, wierd noises or anything.
