also do u reacon i should instal new bearings?

many thanks

 

Don't know what the settings are, but yes all has to be torqued, including a new crush washer to set pinion lash.

if the old bearings are ok then no and u dont torque them u just load them. Then they are locked in place via the too locking tabs also the adjustment on them bearings is what adjusts the back lash between the crown wheel and pinion!. But the pinion bearings do have a drag torque if u have that apart too as the bearings have a certain load on them set by crushing the crush washer!. But u can do this by feel as long as its shimed right so its at the right hight so the pinion teeth mess with the crown wheel in the right place and as for the crown wheel bolts u are meant to but i never have just tight and some lock tight will do fine

 

This tech article shows how to install an aftermarket differential in your rear axle:

Keep in mind the article is focused on the installation of an Eaton clutch-type or a Detroit helical-type differential into an open 7.5" or Cosworth 7.5" rear axle, but the concepts are all the same. At the very least you should notice that you don't have to mess with the pinion stuff at all. Installing a differential in your rear axle is actually not very difficult.

 

U dont have to mess witth the pinion if your not changeing the pinion bearings and setting the back lash is easy if you know how and have a dti
