Title: Gear lube
Post by: 82gmc3/4ton on March 31, 2010, 07:24:51 am

I was wondering what gear lube you guys are using in your axles? What do you guys suggest? I haven't had any problems but I want to change for maintenance. I currently have a front 10 bolt GM and a 14 bolt 9.5 semi-float GM rearend. Thanks

Thanks Vile. Is there a brand or synthetic that you use or are they mostly the same stuff?

I wouldn't bother with synthetic unless you're pouncing on it. I have no preference on brand for stock applications
