‘73 Spindle/knuckle bearings Install w/hub

[Stranglehold]

Is the the inner bearing (front wheel discs ‘73 Dart) an interference fit? Or both for that matter. Is it pressed on when torquing the spindle nut? Trying to figure this out.

New spindles/knuckles, rotor/hub assemblies, timken bearings from Dr Diff going on.

Old hubs come right off the old spindles with inner bearing inside and seal intact.

Just trying to figure out how to assemble correctly

I don't know what you mean by "interference fit" but just drop the bearing in the hub and install the seal. stick the rotor on the spindle install the outer bearing , then the washer, nut , till you take the play out and then the install the castle nut lock and cotter pin . You probably would want to pack the bearings in grease first !!!!
Pretty simple .

Put some grease inside the hub between the 2 bearings. Like uo to 1/4" deep, no more, need air inside also.

The seal goes in gently with a hammer, not driving 16 penny nails here. Wipe a film of grease on the seal edge so it's not dry.

If you mean the cones, no, they are a slip fit, but not really "sloppy." Maybe examine the spindle and bearing, try them first, and crocus/ sandpaper on the rough spots.

MAKE CERTAIN the hub has not formed a "trench AKA sometimes you drive the cup in, and there's damage deep inside, then the cup is loose after install

There's a 73 manual you can download from MyMopar.com. IT GOT there because of some of the guys right here. I think it's in the "wheels" section is the proper tightening/ torquing procedure for the disk brake hubs

Thanks, I’m overthinking the **** out of some of this stuff. The new bearing, being new, were SNUG, but not shop press on tight. You’re on the money!

Right on brother. Got the FSM for ‘73 front end. It’s going in a ‘69 swinger so bit of a mutt

Are you aware of swapping the spindles? Some of us did/ do this to put the calipers on the rear of the assembly, which leaves more room for front anti-sway bars. You also must swap the calipers side to side to keep the bleeders up, and use different hoses. Someone said you can use Camaro hoses, I used ones off I think Volare. They are a bit too long, but putting a half twist in them makes them behave.

Yes, new spindles from Dr Diff. Calipers will be to the rear. I'll check out those hose options, thanks.
