Well I got my 14 bolt a few months ago and after only a few trips out I managed to grenade the yoke so I upgraded to the 1410 yoke. So I get a new crush sleeve and nut and was planning on looking at the old one so I can see how far I need to crush it, but it doesn't look crushed at all, looks exactly like the new one. So does anyone know roughly how far it crushes or a pic? half inch, quarter, almost nothing or what? The other thing is even with the old yoke off it is still kind of hard to turn the pinion freely. I searched and it sounds like you are supposed to be able to just lightly spin it and have it turn two or three times. From the looks of it though the bearings are brand new, the grease still looks like it was just put on so what could be the problem with that. Thanks

anyone I know people have 14 bolts lol
ttt

wow, you might be shot for posting this, SEARCH, ever heard of the tech section.:eek: those should be you reyes looking for it. ill give a head start why dont you look for some kind of inch pound rating:rolleyes:

hey no shit there is a search function??? Take a look at my member number compared to yours and think that over. :flipoff2: No where in any of the 14 bolt posts does it say how much a crush sleeve should crush and that is my question... I know how to test the preload but even without the sleeve crushed it is already way too high so I am asking what could also be wrong since it is all new bearings and races. SO I am wondering what my shop could have f'ed up here. They are the only one around so I can't take it somewhere else and if I take it to them they will say it is fine. So unless you can help don't bother with the search crap.

sorry i should look and not touch, my bad good luck.

lol no problem man, just frusterated. I have seriously looked for DAYS to find this. Hell I even went to the dealership and would you believe i said 14 bolt axle and they were like a what??? Only axles we use are danas! Yeha right so they were worthless, stupid mechanics. And the one shop around is what worked on it already so they are no help. So don't sweat it man :flipoff2: hope someone knows though.

If you have removed the crush sleeve, and its just spinning on "NEW" bearings and races, and the preload is too much seems liek they FUBARed the bearings pressing them on...or at least pressed em too much...

BUT you stated that you have run it and you fawked up a yoke already so the bearings IMO are no longer "NEW"...they are as you stated a few months old and have seen some use/abuse right?
What do you think the shop that set up the axle will do for ya since something is wrong?...I'd wager nothing.

If it were my 14 bolt I would take it apart and see what the problem is with the pinion...you very well could have damaged any of the three bearings...its not out of the realm of possibility...do you have the tools/knowhow to figure this out on your own? if not you could just continue to ask for help form people that cannot see, and or touch your axle. ;)

You do have the pinion assembly out of the housing, right? I mean, it's not difficult to turn because it's pushing the carrier, two shafts, and a pair of 38s, is it?

What kind of preload do you have on it now? The mil spec *says* you can reuse the old spacer when just replacing the yoke. Check it out for details. I used a new spacer when I did mine and set the preload accordingly.

No where in any of the 14 bolt posts does it say how much a crush sleeve should crush and that is my question...


You are asking a question that there is no answer for.
You do not crush the crush sleeve down to a certian measurment, you crush it untill you get the propper preload on the pinion bearings. It is measured in inch pounds of turning torque. I'm asuming it's a 10.5" 14 bolt so pull the 6 bolts and remove the whole pinion support, crush the new sleeve untill you have 20-35"#

The man in the know comes through again.

there are 2 different crush sleeves for the 14 ff gm 85.5 and older is shorter then the 86 and newer so i would guess that if your sleeve is not taller buy about a 1/8 inch then you got the wrong one

Well the bearings are still new, the only reason the yoke broke is cause my friend decided to take the unfinished jeep for a spin and locked up the brakes.... the problem? The spring perches aren't welded to the tubes yet so the axle rotated blowing the driveshaft, ripping off the brakes, and damaging the yoke. So the bearings have not been used at all, well ok 200 feet. The pinion support is removed of course while I was testing all this, but it is way past the 25-35"lbs. You can see in the side of the support there is a hole and thats how I know the sleeve isn't crushed at all. I guess I will have to press out the bearings and races and see if they screwed them up. So I guess I will tear everything apart tomorrow, thanks for setting me straight I guess
