09G Diff parts

[RC51]

Where can I locate new differential bearings for the 09G? Are thay available separatly or do I need to buy the diff/pinion shaft as a set. Wife's 03 NBC has a growling bearing on the drivers side right where the axleshaft leaves the trans. No metal in the pan, no slipping, and believe it or not no VB issues(yet.....). Just a loud bearing on that one side. If you stop the FT/LT tire the noise stops, if you hold the right side you can hear it. I have the trans out and split on the bench The ring and pinion look beautiful, no unsual marks or wear. The spiders look ok. Any help would be greatly appreciated.

What did you see on the side bearings and races? It doesn't have to have pits/chips to make noise, just a flat spot or a single pit can cause noise. Also, I would price out the bearings from Transtar and find out the manufacturer, you don't want to put in cheap Taiwan/China bearings and be in the same boat in 6 months. Then I would call a bearing distributor in your area and price out the same bearings made by Koyo, SKF, Timken, NSK, or INA/***. The number will be etched on the innner/outer race/s. Removing the outer race (in the case) can be a bear sometimes, but don't re-use it. You must, must, must use the new bearing and race together. Good luck!

I already tried to cross the bearings with no luck yet. They're NSK bearings.

I can reuse the races????????? whats the worst that could happen........just kidding

Set up the acct with Transtar only to discover that the parts I need aren't available, new or used.....WTH. Looks like it's time for a new trans. At least I can get a decent price now for a rebuilt unit with a warranty.

I mentioned that your best bet is to either buy direct replacements (not VW or necessarily Transtar) or cross-reference them to SKF, Koyo, of INA/***. You are going to need to remove the race in the case which will have the rest of the bearing info. I am surprised that the spot you saw "NSK" did not have any other numbers or letters, so the rest will be on the edge or top of the outer race. Get that info and/or the OD, ID and width in millmeters and you or I can get the right bearing quickly. These bearings are not special to transmissions so many, many vendors will have these bearings in stock. Good luck!
