Be sure your bearing kit also includes the side yoke bearings and seals. A lot of kits don't. While doing mine I converted the carrier caps from 1/2" bolts over to 1/2' ARP studs. Here are the ARP Part Numbers:
4 x Stud - AR4.060-LB
4 x Hex Nut - 200-8607
4 x Washer - 200-8514
To order you have to call ARP Order Desk & Technical Support: 800.826.3045

You might also have a drain plug installed like in this pic while you have the case at the shop. Makes it a lot easier to service next time.

In case you are interested here is a pic showing the stock 3.45 ring and pinion next to a Viper 4.10 set and a Yukon 4.10 set.
The Viper gear set is quite a bit more substantial.
