14 bolt pinion bearings.

[K5-CJ5]

I have a noise coming form my 14 bolt. I have very minor (if any) pinion movement side to side, but I have a pretty good amount of rotational pinion movement. How much rotational pinion movement should be present?

If I need to end-up replacing my pinion bearings, do I have to pull apart the carrier, or can I remove the pinion support and R+R the bearings seals etc. Would hat affect the back lash in any way as long as I keep the pinion hosing shims the same?

Anything helps, thanks.

No side to side play should be present, yes you can replace the bearings merely by pulling the pinion support but sometimes it can be a pain getting it out, you will need a new crush sleeve and a way to measure the pinion bearing preload

I have a in lbs torque wrench and press for the bearings etc. I just wasn't sure If I would have to deal with the carrier just to do the pinion bearings. The carrier bearings were replaced by PO but not the pinion bearings. Also I was on randys Ring and pinion site and they have an upgrade for the 14 bolt that eliminates the crush sleeve, has anyone tried this?

you need a dial style inch pound wrench to see what the force is not a clicker.

and there is 3 bearings for the pinion. 2 in the support and 1 in case. seen a lot of bad or chewed up 3rd bearing on the support in the case.

and there is this place also for eliminator. little more setup time but best in the end.

and pinion yoke on/off is best with puller or press.

I have the press for the procedure and a dial inch pound wench. I was looking at the eliminators from Randy ring and pinion and it looks like the same deal, Id rather do that then deal with he crush sleeve.

Is there any issue with not pulling the carrier when I do the pinion bearings? I guess it can be done just want to know if its OK as far as the backlash etc if I do not adjust after the pinon bearing replacement.

Can the support bearing be removed without the carrier removal?

best to check b/l and pattern after redo of any part in the system.

and gear oil is out when pinion support is out and few more bolts to drop the carrier and recheck all the past guys ( so called work done ) and you know ITS RIGHT WHEN YOUR DONE

I would get ahold of the crush sleeve eliminator kit, getting a new 14boltff sleeve crushed can be a biotch.

the support bearing can be changed with the carrier in place, but you are so close that you might as well pull the carrier and have a look at the bearings.

a lot of the time if the pinion bearings are bad the end of the pinion gets worn by the support bearing, so take a look at it.

Double checked everything, there is no play in the pinion (lots in the u-joint) and went for a drive riding in the back of the truck to determine where the noise was coming from when decelerating and its definitely coming form the carrier bearing! So a carrier and u-joints are in my future.

Thanks everyone for the info!
