If the normal is 80w90 gear oil ( or another thick oil )then it is fine to use Lucas oil stabilizer.
You just have to be careful nowadays, not so much with differentials but the manual transmissions, many manufacturers are going to atf.
that model comes with a factory rear diff locker
When I changed the fluid in mine it took 3 quarts to fill it up. Also if you have a posi-trac rear end you will need to put in a Posi additive. You can get it at Oreillys or AutoZone. If you don't put in the additive the rear end will make a clunking sound when turning.

there in a plug towards the front by the drive line on the rear end,remove the plug if rear end fluid comes out it topped off.if no fluid (rear end) comes out put fluid in it till it starts to drizzle out.reinstall fluid..if the rear end has not had a service or it smells burnt or is black replace gasket clean rear end with brakekleen and top off fluid...
depends if you are talking about the whole rear end or just the axles themselvs, and yes to both of them but if you take out 3/4 ton axles you will need 3/4 ton axles to put back in and so no. if you take the whole rear end of a 1/2 ton and put in a 3/4 ton rear end it should fit well
My son's 1999 Chevy Tahoe is having a replacement rear-end put in this week. $1100.
Yes
Yes, but it does require quite a bit of fabrication.
1999
if your 2000 blazer is like my '99 (2 dr) there is no separate rear window washer tank; its at rt frt corner of engine bay.
Simply put....Yes
Most probably because it wants to mate.
