Need help w/ Aisin Hubs

Gator · 04-18-2009, 02:46 PM

I just got through putting a new cv axle on my truck and have a question about the hubs. I have Aisen hubs and was wondering if it is possible to put to much grease in there when reassembling everything. Once I got it all put back together, I locked in the hub and spun the rotor to check everything out and it locked in like it was supposed to, but it doesn't seem to be unlocking when Iturn it back to "free".

Please help.....

the guy that taught me said too much grease is just as bad as not enough grease.

too much grease traps in heat. not enough grease creates too much heat

how much should be used then? I literally packed it till it was full thinking it would spread through along the shaft of the cv axle and cover everything.

I am fixing to go back out there and clean some of it out, but need to know how much is good.

Thanks in advance

i'd say pack the bearings good, and put a glob that takes up about half the hub.

iamsuperbleeder · 04-18-2009, 03:29 PM

yeah, too much in the body of the hub will create a suction effect and keep the insides from releasing

when I did mine, I just packed the bearins, bolted all that in, then smeared a little on 2 or 3 fingers and just ran over the inner walls of the hub, and on the outside of the locking spline (for lack of the technical term

), and everything's been working well

Pack the bearings with grease.

Lightly coat the internals of the manual hubs.

And they are "AISIN"

that's the walk-through I followed the first time I did mine

it's a good one

but now I would do them blindfolded, lol

I will pack the bearing with normal bearing grease, but in the hubs, I will use the figure method with white lithium grease. Hasn't failed me yet.

Which "figure" method would that be?

Figure four hub lock?

I've heard that, like falling in love, the figure 4 hub lock is hard on the knees.....lol

LMAO... that is what I get for not proof reading my post!! Just to clear it up FINGER... not FIGURE...

Thanks for pointing that out!

abecedarian · 04-18-2009, 09:43 PM

so... this would be the trademarked "RaginYota finger 4 hub lock"?

Gator · 04-18-2009, 10:04 PM

Thanks to all. I got it figured out. I had not ever done a 4x4 service before and had a CV axle that was about to go. I went ahead and did the same as what all of you advised and it worked beautifully. One needed a little TLC, but it works better than ever now.
