Newbie with a bad pinion bearing

[jedavisss8]

Hi All -
Have a '95 Pathfinder 4x4, LSD, auto.  The pinion bearing is going south.

I could:  Have my local shop rebuild the diff ($850)
             Try to do it myself (about $500 for the whole kit, and I've never done this)
             Get a replacement diff from a junkyard - not as reliable but a lot cheaper

Question:  what axle ratio do I have?  4.625 or 4.636.  Tag on the front fender says HG46.

Any help is appreciated.  The whine is getting to me.

p.s. - that's whine, not wine.

Should have thought of this before. Went to the local dealer with the vin. Computer showed it has either 4.375 (hg43) or 4.625(hg46). Plate on the fender says hg46.

If you ever need to look anything up by vin in the future, give me a ring, I can do the same thing.
Also I thought I told you about the axle code on the fender.
Sorry if i didn't!

Hey Steve -
I'm finding a number of used differentials on Ebay which have rear disc brakes.  I realize I probably would need to get the calipers and pads and maybe a longer or shorter brake line, and the correct master cylinder.  Are there any other issues with doing this swap?  Also, finding some diffs that are not lsd.  Advantages/disadvantages of not having lsd off-road? 

Just got the rig out of the shop for a check out and fuel leak.  Found out I also need both front axles as the boots on both are shredded.

if I remember right the existing brake line is long enough. 

LSD is preferable off road. unless you're planning on putting a locker in.
