Corporate 10 bolt gear change

Chris,
The axles move out and in about 1/8th of an inch. They don't move up and down. There seems to be too much slack at the c-clips holding the axles in place.

Stock shafts?

The rear end is a limited slip also. The carrier bearings can be seen to shift slightly in the oil, but the caps are still on tight.

I asked about the limited slip because they can make noise while turning if they're worn or don't have the correct limited slip additive.

What do you mean by "I can see the carrier bearings shift"? The carrier bearings should not be able to move in any direction. If you can move the carrier side to side, you don't have nearly enough shims in there.

Upon final assembly, you should need to lightly tap the carrier in with a hammer. If you can install it by hand, there's not enough carrier bearing preload. If you can move the carrier side to side, there's zero carrier bearing preload.

Maybe one of the carrier bearings didn't get pressed on all the way?
 
Chris,
Which additive do you use for limited slip rear ends? I don't believe I used any. Also, the shafts are stock.
I was able to install the carrier bears by hand but with effort. The original carrier just fell out upon disassembling and I thought the new spacers were tight enough. I will install some shims and get it in there tighter. It is getting late here and the project will have to wait until tomorrow. Do you know of any good instructions on how to set the carrier bearing preload properly?

Well, I suppose it depends on which limited slip is in it. Is it the stock Eaton gov-lok (G80)? Or is it something else? (there are tons of different limited slips for 10 bolts thanks to the racing crowd)

Before you mess with taking anything apart, does the carrier move side to side? When you move the shafts in/out, does the carrier move side to side?
 
As for setting carrier bearing preload, this is an excerpt from this gear setup article on pirate:



[FONT=Arial, Helvetica, sans-serif]Carrier-bearing Preload
Definition: See pinion-bearing preload
Think of it as: How tightly the carrier-bearing cones are pressed into their cups and consequently how stiff they are to rotate. Also controls how tightly the carrier is held in the housing.
How Measured: Not possible to measure directly.
Adjusted Via: Adding or subtracting an equal amount of carrier-bearing shims to both sides of the carrier. Ideally, total carrier shim stack (sum of both sides) should be approx. 0.015” larger than the available space, and a case spreader should be used. However, a case spreader is not critical, and a good approximation of carrier-bearing preload can be made by ensuring the carrier can only be installed with a few good blows from a dead-blow hammer.
Note: If carrier preload is too little, carrier will move away from pinion under load (squirm or deflect), increasing backlash. This could lead to insufficient gear tooth contact, resulting in chipping/breaking of gear teeth.[/FONT]
 
Chris,
The carrier does not move alot, but you can see the shift in the roller bearings and feel some slight movement. Not sure about the limited slip model. I will have to research it.

The carrier shouldn't move side to side at all, so if it does you'll need to add some more shim.

Pictures will help ;)
 
As for the in/out movement, its either caused by too few carrier shims or it might just be the nature of the beast; c-clip axles don't retain the axle shafts perfectly (though 1/8" sounds just a little excessive to me).
 
Chris,
Thanks. I should have known to add it to begin with. The instructions I was following had it in there, I just skipped over it for some reason.
Thanks for the help and I will get back with you tomorrow on how the carrier preload works out.
Wes
 
Kenny78,
Thanks for the reminder. I am getting ready to get back into setting the carrier preload today and I have the article from Bill Ansell at pirate4x4 so I should be set. Just have to remember to have lots of patience!

My post got cut short somehow:dunno: It was supposed to go on about how I havent setup gears yet and didnt want to talk down to you. So best of luck, amd it looks good otherwise:waytogo: Post some pics of your truck when ya get done:cool1:
 
Kenny,
I didn't take it that way at all. I need all the help I can get. Advice is cheap, new rear ends are not! Take it easy!

Chris,
Just finished getting the carrier bearing preload set properly this time. I had to hammer in the shims with a regular hammer and plastic punch with some effort but not enough to damage the bearings. My first attempt put the gear pattern a little to the heel side so I thought I would move it to the center by .003". I didn't know that .001" makes alot of difference! I ended up with this pattern:http://i274.photobucket.com/albums/jj248/wesjoy70/IMG_6169.jpg
Well, I am going to go and eat some pizza with the family at the new Pizza Hut nearby and I will be at it again when I return. The wife is not too mad at me about spending all this time in the garage. Check back with you later!
