its the outer axle bearing. not the ones in the knuckles.
there is no flange machined on the axles so red locktite is required so they dont work their way out of the axle housing and up against the CV joint

Make sure everything is clean so the Loctite can get a grab.

Wondering if there is enough room to get a narrow collar with a set screw or two in there.

Cutting a groove into the shaft to accept an E-clip won't work as it would introduce an obvious weak spot into the bone.....

My bearings are dead, in lots of pieces, I need some more

SDS Customz · 03-11-2010, 10:48 PM

I didnt forsee this being this big of an issue. Ill come up with a cure this weekend. Ive been sick so it might be at the end of the weekend.

indiana mudcat · 03-11-2010, 11:08 PM

I put loc-tite in and outside the bearings today, a healthy coat. Also I got to thinking that when I screw the C's on it spreads the ends of the axle a little, so I added extra set screws in the C's hoping to clamp the axle tighter on the bearing. Deff kept the C's from slopping, I'll test a little tomorrow and comp Saturday and see how it works.

SDS Customz · 03-12-2010, 10:31 AM

a very small amount of ca glue will set the bearing on the shaft(and quickly as well) I would suggest pre-assembling the shafts into the housing and then pulling them out just a little bit and adding the ca. once glued the bearings are challenging to get to move. I think the issue depends greatly on the housings u have and the c's. in my testers the bearings didnt move out. Though issues always show up when a large group of crawlers get ahold of anything!!

Stormin2u · 03-12-2010, 11:33 AM

Received mine yesterday just waiting on VP high steer 0 ackerman knuckles my question is are you putting the (red lock tight/super glue) on the axle or the Cs?

DeweyCJ5 · 03-12-2010, 11:52 AM

i have the axial c's and the bta and i have not had any bearing walk yet

Phylodog · 03-12-2010, 01:44 PM

I tried putting a short piece of heat shrink on the end of the axle leaving about 1/8" overhang then heating it to create a lip to hold the bearing in. Worked great until I went to put the C's back on and they wouldn't fit over the heat shrink.

I failed.

Again.

Lol

gunnar · 03-12-2010, 01:52 PM

How about putting a small spacer on the axle first, then sliding the bearing on? Might take a few tries, but it should work, I'll try it when I get around to installing mine.

i'm having no troubles now with the red locktite so i have no complaints

if i'm thinking of what you are thinking it would interfere with the cvd joint.

that sounds like a good idea. not sure how you wouldn't be able to fit the C's back on though

here is what i picture when you described what your talking about. the black would be the heat shrink and the grey would be the bearing

Phylodog · 03-12-2010, 04:20 PM

I actually tried putting heat shrink around the axle housing rather than the shaft. The shaft, as you demonstrated, might just work. I'll have to give that a shot.

romulus22 · 03-12-2010, 04:25 PM

ahh i understand what you were trying now

I think that it totally depends on the clearances that are in each individual housing. the test housings also had no issues

in both cases the application would be to the bearing surface of the shaft. apply lightly (so as to not have it get up on the side of the bearing when the bearing gets slid on) and then slide the bearing on. the red loctite is how the bearings are retained in the end of the berg tubes. in this application there seems to be enough tolerance difference that the red hasent spanned the gap/stuck to the plastic. so my thought was to try the ca glue on the bearing surface. It makes it rather hard to remove the bearing(im sure a little heat and they would slide right off).

Im sure this worked well also. it would have kept the two halves of the housing from spreading, and allowing the bearings to walk.

Waiting Dragon · 03-12-2010, 07:18 PM

I'll try all of the above once I get the new bearings. I think I will also try some type of shim between the housing and the bearing.

Stormin2u · 03-12-2010, 07:40 PM

Removing the bearing from the shaft when ca glue is used shouldn't be that tricky with a pencil torch.

Just so I'm on the right track the bearing is glued to the shaft and I should try the red Lock tight first as it works in some situations just not all.... or just go straight to the ca glue method for installation?

romulus22 · 03-12-2010, 07:46 PM

the red locktite is working great for me. i just pulled mine apart to regrease them and had a heck of a time getting the bearings off of the shaft.

I should have been more detailed. What I was thinking of would be a small, tight fitting steel ring that would prevent the movement, and not hit the edge of the cup, much like your little black mark next to the bearing in the pic.

romulus22 · 03-13-2010, 06:02 AM

that would work as long as you could get it to stay still.

Romulus what Cs (manufacturer) are you running?

Did you use heat to remove your bearings?

romulus22 · 03-13-2010, 08:22 AM

pretty sure they are made by golden horizon. just some cheapies

i didn't add heat to remove the bearings. tapped it off using the top of my nut driver.
