I'm planning to reassemble the rearend for my '21 as soon as the ring gear bolts come from Lang's. I'm wondering what to use for assembly lube. I plan to put 80/90 or 75/140 lube in . I have the modern outer seals. What would you use for assembly lube ? Oil? 80/90 or 75/140? Grease? Something else? What say ye?
Steve J ?
I've always used wheel bearing grease. (after a dry fit of course.)
The grease is very useful for "glueing" the steel thrust washers in place while assembling the rear axle. For other parts inside the differential any oil would also do fine.
I use Lubriplate because I have a big tube of it left over from other projects.
Before you use the multi grade lube you might want to read this;
I pack the pumpkin with wheel bearing grease.
Tommy, in previous discussion on this forum, it was noted that the modern 140 is close to the old 600 weight oils. I'd suggest using the 75/140 lube. Royal Purple states it is not corrosive to yellow metals. http://www.royalpurpleconsumer.com/products/max-gear/
I used a bit of wheel bearing or regular grease placed with a solder brush for the steel thrusters and just oil for the thrust bushings and other bits.
I'm scared of plugging the slots in the thrusters with grease but that fear may be unfounded. I don't know.
I also fully opened the ends of the slots with a file as the mill didn't run all the way off the end of the surface on my thrust bushings.
Get some grease on the inner Hyatt's for the first bunch of turns is how I take THE book. ;-)
Interesting article and have seen those warnings before about "yellow metals" and some gear lubes. No GL-5 and perhaps no GL-4 either is what I gathered. Go for the GL_3 or GL-1.
I bought 600w from the vendors. Not for use with Ruxtell's. Too heavy.

I agree with Keith plus a little Lucas climbing lube
I just thoroughly lube everything with the oil I'm going to use in the rear axle.
Get 600W from the vendors, its cheap and made for T's and A's. Cheaper than Royal Purple as well.
Spent some time reading the labels at my auto parts store. It seems like all the gear oil they sell (Gl4, Gl5) is made of a Snake oil derivative ...perfect for every application!
