Question on a race 8-3/4 axles.

It's hard for me to believe that the housings aren't straight and if they are off you need to straighten them. I have done 10 or so housings most D60's cut them down and weld on new ends and when my friend ran late model stock cars we did a lot of 9" fords.
If the axle slides in nice without the o-ring on the outside of the bearing then it will work fine and wont ware out the bearings or cause a failure, and if you look at the ad that you posted for green bearing it ask what inner seal do you need, no where does it say leave them out. I'm just saying. I just cant see the point of leaving out the seal.
.
Maybe you need more motor to flex the housing. I wasn't referring this to the Dana 60 but I'm sure that they Flex also otherwise they wouldn't put that aluminum back cover on there with the bolts to brace the inner caps.
That was not an ad. It was Dr diff posting of why he doesn't use the early bearings. Which was the question that I was asked what was wrong with the early style bearing.
I'm happy that you can narrow an Axle and Slide the axles in with no problem.
As for the inner axle seals I repeat some people use them and some people don't. You will notice in the bearing set that I posted it did not include an inner axle seal. But the old style that you showed has them. So it gets down to if you want to use them use them if you don't want to use them you do not have to.
Do you have a problem with my not following you blindly? If so pm me and lets see if we can work it out.
