742 axle and diff question

[71 Bee Man]

G'day guys,

because there's no-one else here that I can ask for help, I'm hoping you can give me asome basic info.

In 3 weeks time I'm taking the family to the States, and whilst over there I plan on buying some bits for my 71 Superbee. In particular (as some of you may remember) some diff parts including a Sure Grip center.

My question :

What bits in particular should I look out for ?
ie. what specific LSD center
Should I pick up a new ring gear and pinion, or are these normally machined ?
Bearings
Basically.....what am I asking for or looking for ? To see what I currently have please visit this following topic link :

I know this probably sounds like a dumb question, but I want to make sure I get the right items. I have a bit of a "whine"in the diff on decelleration after the pinion nut became loose on a long trip, and whilst it's driving after being tighten3ed, I plan on getting it all fixed up when I return.

Any help or advice is appreciated. Whilst on the rear end, with regards to axle bearings I've seen there is a kit called RP400 which seems to be a complete replacement for the axle bearings. Is this used on both sides or what ? I'm used to simply replacing the actual bearing and seal, but this seems a complete unit.

Thanks,

It depends on how far you want to go.  You cna order a complete center section with new Sure Grip and new ring and pinion in the ratio of your choice and new bearings all set up and ready to drop in.  Or, you can get the individual pieces to do yourself.  If you plan on doing it yourself and just want the parts, there are still a lot of options.  Auburn is remaking the cone style lsd and it is probably the least expensive of the various ones out there.  There is a reason it's the cheapest of course, because it's the least rugged.
I think the axle bearing kit you are talking about is the one we commonly call the "green bearing" kit here.  Some people love them and some hate them.
