If I chose to keep my stock ring/pinion set and just upgrade the locker
inside differential. Do I need to readjust the ring/pinion set after the new locker installed?

 

if you're asking if your gears will need to be set up again by a professional, i would say yes.

 

The work involved to install a locker is identical to the work involved to regear ... that is why most folks do them together to save from having a double expense.

 

The 2 crucial items here ring gear backlash and carrier bearing preload. Check your ring gear backlash before the old diff is removed and copy it when you install the new diff. No pinion adjustment is necessary as you are reusing your gears. Bearing preload is a bit more complicated but still fairly easy.

 

So, even if I just want to install a lunch box locker and keep everything else,
I still need to readjust ring/pinion.

Is my understanding correct?

 

yes. even though things should go right back together without any change, more times than not, there will be. so long as you can do with dynatrac just said, you should be fine but, the question is whether or not you know how to do it.

 

No adjustment to ring and pinion for a lunchbox locker.

 

Are you sure, from what I read, even intalling a lunch box locker requires moving the carrier
out of differential house, replace the stuff inside the carrier and reinstall carrier back. Since
ring gear is bolted on carrier, this to me means some shift will happen between pinion and ring

 

WayofLife:

Thanks for your reply. Do you have any writeup links on

install lunchbox locker
install LSD
install auto locker
install ARB locker
install OX locker

You see, I would like to try if I can try something myself and before that I want
to educate myself first.

Thanks again!

 

I was confident I could of done mine,but when I stumbled upon a shop that would do it for 40 bucks.I jumped on it.
