At that point, when there is meaningful pressure, it would be equal on both sides.

Have you already come up with some side gears or a replacement diff unit?
I guess I will blame it on the Prior Owner!

Since it is not a Mercedes I am going cheap; am guessing the Motive Gear set is made in China.
This Van drives around Town and occasionally to LA no more then 20 miles in one direction. I have never towed anything and have no plans to do so.

I bought all of the below stuff from eBay with Free shipping and am still waiting on some to arrive. I already have the parts in Blue and am waiting for the rest.
1 each Motive Gear GM7.6BI Gear Kit total cost $102.50 eBay
2 each Torrington US Axle Bearings total cost$32 (exactly the same as I removed from the axle) total cost $30
2 each AC Delco Axle Seals total cost $12
2 AC Delco Carrier Bearings Timken USA total cost $25

The Pinion Seal has also been leaking but not like the Axle Seal Was. I was supposed to drop the Driveshaft to day and get the Number off of the Seal but did not get to that. Will be ordering more parts.

If you have some part numbers to start shopping with (you can eventually cross reference them to other companies numbers) you can get the good quality Bearings and so on at a fraction of the Price on eBay.

And, of course like the rest of the Job one thing leads to another. Besides the Pinion Gear Seal the rear Transmission Seal leaks and since one end of the Drive Shaft will be coming off I guess that other end is also to fix the Trans Seal Leak.
May do the U-joints also.

One seller on ebay is selling Despite the description this is a complet New Limited Slip type Differential Carrier.



Chevy S10 S15 Astro Safari Rear Axle Differential NEW!!

$249+$23 shipping.

I thought about that but I have no particular need for the a limited slip Differential and I have never had to go this far working on a Differential before.
I may or may not be changing the Pinion Gear Bearings.

I have the real Chevy Service Manual for My Year and Model of Van (parts book to) but the description of the rebuild is kind of sketchy and there is a need little Tool for help with setting the Carrier Preload I do not have.

I am hoping that by buying the exact Same Carrier Bearings I will not need to mess with the Carrier preload.
I have Micrometers and Dial Indicators and so on and when I get the New Bearings I can measure their thickness to see if they are the same dimensions.

The Pinion Gear has a similar Crush Sleeve arrangement as the Mercedes to set the Bearing Preload.
I suppose if I have to change the Bearings I can use a Depth Mike to check the Original Height/Protrusion of the Pinion Gear into the Differential but I don't have the Tools listed in the Manual for that.
