Bad Rear Wheel Bearing, can I still use this diff?
'97 Blazer 4door, 4x4, LT. So the bearing was bad. Really bad. Inches of play bad.
I get the axle out, and this is what greets me: https://blazerforum.com/forum/member...went-19510.jpg Yeah, I need to replace this shaft. https://blazerforum.com/forum/member...side-19512.jpg Compare with the other side: https://blazerforum.com/forum/member...side-19513.jpg So this was the temporary bearing surface, not as bad as I was expecting: https://blazerforum.com/forum/member...face-19514.jpg I can fix those things, but my question is this: Can I still use this diff or must it be replaced? This is the magnet, and there's a lot more in the gear oil. Even if it all came from the bearing's death/the shaft's weight loss and NOT from the gears... did having this in the oil damage the diff components? https://blazerforum.com/forum/member...more-19516.jpg Here are some pics of the diff, I'm not finding a lot of metal shavings on it: https://blazerforum.com/forum/member...k-ok-19515.jpg These spots aren't metal flakes, the camera reflected funny. https://blazerforum.com/forum/member...k-ok-19511.jpg Tell me what you think, is it re-usable if I clean it up? The gears look fine, there aren't any teeth missing or anything. |
if it where me i would re use it if no teeth are damaged, should be no problem. i might try and clean it out a little tho. is that a G80? looks like it.

I've given it a can of brake cleaner's worth, and it does look less brown.
It is a g80, with 3.73 gears. :) I'll replace the bad bearing and run it as is with new oil, doing another fresh gear oil change soon. If the other bearing is bad, it'll get done then. |
I'd do both anyway, little security for the future
