[Half-Inch Stud]

The Timken outer races are loose in their housing ends. And each Outer race has a little play in each housing end.

The wear surfaces look excellent, but is "loose" and two finger install and removal normal!

What ever happened to Press-fit?

[mike leech]

I run a sealed bearing. And it is not particularly tight in the housing ends

[Half-Inch Stud]

My 35-Spilne axles have tapered Roller bearings pressed on.
The Outer Race is "not particularly tight" in the housing (they is loose).

Certain that "loose" is the way STRANGE Engrg made and sold it to me. Sooooo seems I'm in need of a Lesson in Bearings 101

My S 60 is the same way, ran it all last year, did not leak a drop.

My dana 60 green bearings RP400's were pressed in the axles, Now I wonder.

Hmmmm, i never mentioned that both sides leaked like sieve since new. Strangely it drained out 2 quarts upon cover removal.

Are the RP400s straight or tapered roller? Not ball bearing?!

Holy C-Clip Eliminator Batman! An internet search on th RP400 (Green brg mfg oem) brought up the diff doctor and oem vs 2nd gen rp400s. Either RP400 is waay different than what i got.
I can see that the 4-5 bolt flange takes side loads well. but Does the 4-5 bolt flange handle the car weight and forward accelerations!?

If the RP400 outer race is loose in the housing tube then the car weight, Slick and HP loads make for a bearing that will want to depart from its flange huh.

Have you called Strange?

Years ago when the recently new rear was installed and driving, and leaking, they were no help. So, i had no way forward. Been 20k miles of ignoring the leak, and no internal harms done. I might call Strange again, but seems this avenue can be more fruitful.

So, far i'm leaning toward using a thin steel tape as a band shim, to shim each Outer Race upward against the Housing end for zero play under car weight and accelleration. Colt Race and warmed Housing end could allow a pressfit. Would be better than "trowing it back together".

The rear in my car never leaked, there is a seal in the housing both sides, the bearings themselves have two O- rings each, plus the metal gasket. By the way axles are Mosier 35 splines.

DITTO: redundant axle seals :
inner seal pressed into HSG and wipes the shaft retention collar.
Outer seal trapped on axle and wipes the axle OD, but this seal is trapped by the 4-bolt retention metal (what an odd design) and my rear caliper plate.

--> Outer seal evidently loose in HSG bore like the Outer Race was, so RTV might be the new sealing solution.

--> Curious how lube gets or has gotten to the tapered roller bearings. Despite good wear appearance (and no pittings) the bearing look like they might have seen some heat (probably 4 hours on highway) but not much heat.

I have a strange s 60. One thing I did do is get lock tite. The green stuff it is for sleeves, high heat. I put it on the outside of the races. No issues yet!!
I did not like how loose the felt either.

I dunno. maybe on the unloaded side. I can still hope that steel tape goes in tight.

Yea, Spoke to "Jake" in Tech. Jake said, the outer race is loose by design, when disassembled.

Said either way to my comment on shimming the race with a thin steel "feeler gauge like shim, that some folks shim the race but doesn't matter.

Said the Tapered Roller i have is the best bearing, that the straight roller is not as good for Street/Strip.

Said, that as long as the preload is there upon tightening the 4 Retainer bolts all is well.

So, i put it together, (so shim job) & the retainer has plenty of preload and seems to roll with low friction, filled with 2- Quarts of RedLine Shockproof and drove it. Seems fine.

....a loose outer race breaks every rule in the bearing handbook. Suppose THIS STRANGE axle application is rather clever. The 4-bolt retain plate presses against the outer seal metal that pressed against a steel ring which presses against the Roller Cage.

Soooo, the Roller cage, steel ring, seal and 4-bolt retainer don't spin. Outer race doesn't spin.
Soooo, the Axle & Tapered Rollers spin in-place, but the Tapered rollers don't orbit?
Doesn't that make them Tapered spinners, since they are not rolling around the race? That would allow the outer race to get dug by the rollers, and the cage would need to allow rollers to spin.

Suppose the Rollers are orbiting the Outer Race, then the roller cage must be able to rotate. Then there must be a thrust bearing function somewhere. I didn't see it, and my eyes work pretty good.

May call ole Jake back....

[Half-Inch Stud]

Called Strange back: Edwin in Tech explained what it is and how it works.

It is a Timken Set20 Standard. It works by having the 4-bolt retainer plate apply a preload press-fit of the outer seal lip into the Outer race. The Outer race has some of the OD cut away to allow the Outer seal to occupy that area, and takes out the Outer race slop with the Axle tube, and also sets the bearing play. So the Rollers and Cage do orbit and all is well.

Not an intuitive bearing to understand how thrust loads are taken, nor how bearing engagement/play is set, even with the parts in hand.

Hope this helps somebody somewhere whose sweating bullets wondering how it all goes well.

Thanks... not as obvious as truck Dana with floating axles.
