please,need some pro opinion,this is a 4.88 yukon on a elocker with .077 shim and .007 bl.

 

too deep

 

this with a .072 shim. this patterns are turning me nuts.

 

common guys need your help.

 

lol, tooooo shallow now.

Do you have enough shims?
Are you making sure your calipers are acurrately measure the shims?
Are you using a crush sleeve or solid collar(which at this point you shouldn't have installed in order to do the gear mesh)?
How much pinion preload are you putting in?

 

Herro prease???

 

.075" maybe the number you need.

Have you looked thru Zuk's website? www.gearinstalls.com

 

Boom.

thanks for your response.first was a stock 077 shim now using yukon mini kit.triple check the measurement.crush not yet installed.maybe my problem is the preload,my small torque wrench n inches have a large scale.

 

tonight spend. near 4hours on zuk site.the more iread and compare the readings the more confuselol

 

It's hard too say exactly what the problem is without being there.

Are you actually MEASURING your shims? That could be an issue too.

Are you lubing the pinion bearings with gear oil to get a good preload?

How accuarate is your CBPL (carrier bearing preload)?

I've built numerous diffs (majority were elockers), and only ONE has "fallin together" on the first shot. I still tripple checked it

 

ummm.no lube at the bearings.

 

Fix it yet?

 

will try this night aftwer work.lookibg for a good torque meter

 

how about now.
with 10bl
with 7 bl

 

What's the pinion shim?

 

.082,lubed the bearings now first shot was at 10bl sec shot at 7bl.

 

what you think? ok? still out?

 

Hi Mandy --- I'd like to see you try 094 and if you could load the pattern the same way I do. Secure the 3rd...hold a rag on the pinion flange lightly while turning the ring gear with a 17mm wrench back and forth 3 times.....you will have a good easy to read paint then. 007 is ok on BL

 

yes sir,will do tomorrow,thanks guys.
