Ok, I've spent the last 2 days (about 10 total hours) researching grease for a Toyota truck 4wd front axle application. I've read some very good posts with some very good points but a true answer is never given. Maybe this thread will provide all the future searchers an answer, so here goes.
I'm rebuilding te front end in my 95 land cruiser. The factory specs a lithium based moly added grease. There are several options for this. Problem is Toyota specs a high temp wheel beating grease non moly for the bearings. Inside the knuckle it is absolutely impossible to keep the two grease separate. The knuckle geese will ALWAYS end up in the trunion bearings and vice versa. And in hot temps the liquified knuckle grease will travel down the spindle an mix with the wheel bearing grease, and vice versa.
In my non full time 4wds I usually just use high temp wheel bearig grease throughout, it doesn't get used enough to hurt the axles. In this and other full time Toyotas, having the moly is a bigger deal.
I say all this in an attempt to spare us all some time in the long run.
So can a 3% lithium moly such as cats moly3 or a 5% calcium sulfonate moly be used in the trunion and wheel bearings on a heavy 4wd vehicle. If yes, awesome. If not, then I'll just use high temp throughout and take it all apart and repack everything more often.
I apologize for the long post, but I wanted to try to cover most bases in the first post.
Thanks very much for your time.
