Thats kind of what I envisioned happening if someone broke their hubs. That or some of the teeth that grip the splines of the CV shaft sheering off. I guess all of them would have to sheer though.

 

Most manual hubs don't just "slightly" fail or lose a spline...all I've seen that failed were in pieces afterwards as in catastrophic failure. Every Aisin I've seen that failed was a result of something else failing, like a wheel bearing, and not the cause of the failure. If you want something for hardcore wheeling on a Toyota, stick with Aisin. I think there is a reason you don't see Marlin, Trail Gear, All Pro, and FROR or any other big name Toyota parts places selling Warn manual hubs.

 

only bad run in with hubs ive had were superwinch hubs i had on an old k5 blazer..my driver side wheel hub got so stressed it shattered everything inside of there..other than that ive got the oem on my runner, and ive run warn on my jeeps with no probs...

 

Never broken an actual Warn hub (or an Aisin for that matter) but I have had hub-related damage. A fairly common issue with Warns is the lack of the cone washers that lock it in place like the Aisins. If the nuts come loose, then the possibility of shearing off the mounting studs becomes very real. Happened to me, I sheared off all six studs and the two locating dowels on one hub. Had to finish out the trail with the hub duct taped in place to keep dirt and crap out. Thankfully I was welded so I still had one front tire pulling for me. Went back to Aisins immediately thereafter.

Another issue with Warns is that they stick out quite a bit further than Aisins. Come down on one on a rock, and you can kiss it goodbye. This could also be said of the Aisins but the shorter length decreases the possibility.

 

Mmmmm, a little blue LocTite solves that problem.


I ran Warn's on my Jeep for over two years, through some of the toughest (rocks, big rocks) trails here in the SW and never had a rock bust one.
The only thing that I ever had happen was getting the left side of the Jeep (side of the tires) really, really jammed against a rock face, going up a realy steep waterfall, and the rock unlocking the left front hub. That was interesting

For solid axle rigs:
Warn hubs at 5000 ft-lbs
stock Aisins hubs 5800 ft-lbs
drive flange 6000 ft-lbs
Birfield 4200 ft-lbs
Inner axle 5000 ft-lbs.
Stock rear axle, 6500 ft-lbs

 

BINGO! This is exactly why - I might be taking my Aisin hubs off and saving them as spares (and putting my spare Warns on instead). I am getting longfields on there - so now my weakest link will be my 5:71 ring and pinion. I would MUCH rather my hubs go than my Ring and Pinion.

So while Aisins are in fact stronger - there is an advantage to knowingly using a weaker hub - especially when it is the easier part to replace AND it is under warranty!

 

Be aware that if you blow the inner hub gear it can damage the splines on the birfield...and will not be warrantied by Bobby, unless you are running his chromoly hub gear.

 

If your hubs go as mentioned above you are going to fubar a birfield and with Warns they won't be warrantied...or with Aisins, unless you have the hub gears.

Sounds like a catch 22.

 

and if you go with the CroMoly hub gears, you're back to the R&P being the weak point?

 

Sounds like it is time to yank the 5.71s outta there...cause I don't understand why you WANT a weak point?

 

I don't want a weak point. But I would rather wait till my 5.71's break before I do anything there. (We thought they had broke but it was my birfs instead). The reason I want to stay with 5:71's - When they are cryo-treated they are no weaker than 5.29's and such.

And well... I really need to stay with 5:71's for this reason. I have a 3slow automatic in a heavy ass 2nd gen on 35's. I want to be able to drive to Moab AND I want to save my engine and trany (newly rebuilt) it is a heck of a lot cheaper to change out 5.71's rather than replace the engine and tranny. With the hills we have here in colorado - anything less just puts too much stress on my engine while running 35's...

So that is why.

All the above factory manual hubs were Aisins and they are well loved by the masses.

I had auto hubs on my Nissan and switched them out for Warn premiums for about $140 a few years ago. They were excellent hubs.

Oh, and anybody buying Warn premiums hubs for $500 a set, I'll sell you as many sets as you want for that price!!
