IRS Hub mounting question.

[E-Ticket Ride]

I have the DS LCA & UCA mounted, axle in, and spindle (knuckle) mounted to the arms. The hubs slide onto the axles fine by themselves, but when trying to slid them on into the spindles over the axle they "stick" after about a 1/2" of insertion.

I then tried to slide the hub into the spindle of the PS (not mounted, not onto the axle), and it does the same thing. I have tapped to try and "persuade it" on further, but no dice. I didn't smack it too hard, as I didn't want to muck it all up right away.

So then I stuck the hubs in the freezer overnight, same thing.

Now I have both the PS hub and spindle in the freezer for the day and will try that tonight. Is this tight a fit "normal", or is it something that I am missing. Any alternatives or suggestions would be appreciated.

TIA
Chris

The hub should be pressed into the spindle first. It should not be a slide fit. The axle should be a tight slide fit once you have it assembled in the spindle

The hubs were a nice tight, but slid on fit themselves.
Now to find a press that I can borrow.

Thanks

My favorite way to install or remove bearings in aluminum parts is to heat them up. I am not sure how much of a press fit Ford uses on their knuckles but on all the upright I have had in the past I put the assembled parts in an oven set for 275F-300F with space under the bearing and when the parts were heated the bearing would drop out. I purchased my knuckles without bearings and bushings so I didn’t remove my old bearings but I did used this method to install the new bearings and it worked very well. I am not sure how high of temperature the bushings will stand so I didn’t install new bushings until after the parts cooled down.

I managed to install the hubs this weekend with the threaded rod approach.
Is there a spec on the depth of install, like gap between the back of the hub and the front of the spindle to check for proper install depth?
I tightened until I perceived I would break something as the tightening effort got "really high" if I continued.

Managed to complete the hub installation by taking to a local shop that handles the mundane stuff on my DD. The completed the press in and it took all of 2 minutes, and for free.

Back to installing the spindles later this week once I get home from a business trip. On to rear brake install next!
