Better Bearings?

i wanna do away with roller bearings in my tranny and transfer case, and i wanna know what to do. yes, it's probably already been discussed.

 

DANA18-INT : Intermediate Gear Kit retro fits the Dana 18 With Tapered Roller Bearings for noise reduction & performance | Advance Adapters

 

There is a sealed front bearing for the T-90.

 

how about rear bearings?

how does that advance adapters kit work?

 

Rear transmission bearing? The T-90 and Dana 18 share oil, so there's no need to seal the rear transmission bearing.

Interesting that is a metric bearing in a transfercase no doubt designed in 1940.

And whether or not you want a sealed rear transmission bearing depends if you swapped the transmission. I think my B has a 307S in the AA tail housing adapter.

 

You need to get the intermediate gear machined for the roller bearing cups and then it goes together just like a front wheel hub with an adjustment nut on the front side. McRuff can machine the gear.

 

One reason I could see for putting a sealed bearing in the rear of the t90 is its propensity for pumping oil into the transfer case, overfilling it and then leaking.
