]2eDeYe Posted April 20, 2007 Report Share Posted April 20, 2007 So, I'm picking up some hardbody 2" drop spindles, rotors and calipers. Can I use 620 disc brake hubs with this combination? Or, will I need to get hubs and bearings from a newer truck? Quote Link to comment
spiffinspudater Posted April 20, 2007 Report Share Posted April 20, 2007 Are you putting them on your disk brake 620? I was thinking about drop spindles for my truck also so info as you do it would be great! Quote Link to comment
]2eDeYe Posted April 20, 2007 Author Report Share Posted April 20, 2007 If you want to call the pile of parts in my garage a disc brake 620, then yes :D Quote Link to comment
tangent Posted April 20, 2007 Report Share Posted April 20, 2007 Question here if you flip your spindles on a 521 is there any front end geometry problems.. I realize the holes on top and bottom are diffrent diameter, but what about the geometry.. Quote Link to comment
]2eDeYe Posted April 20, 2007 Author Report Share Posted April 20, 2007 I would think their would be no camber change at all with that method... Now get out of my ball joint thread :D j/k :P BEEBANI...has actually done this so he would know for sure ;) Quote Link to comment
BEEBANI Posted April 20, 2007 Report Share Posted April 20, 2007 No camber change, it was actually better. Quote Link to comment
Redd Posted April 20, 2007 Report Share Posted April 20, 2007 so the hardbody spindles fit the 620 disc brake? Im new to this so wanting to make sure im reading correctly:cool: Quote Link to comment
]2eDeYe Posted April 20, 2007 Author Report Share Posted April 20, 2007 Well....that's my question really...hasn't been answered yet. I'll find out one way or another tho ;) Quote Link to comment
Bleach Posted April 20, 2007 Report Share Posted April 20, 2007 The whole spindle assembly on a 620/720/Hardbody bolts on using the same diameter bolt on ball joints. So basically the entire spindle assembly is interchangable. You will need the Harbody HUB to go onto your Hardbody drop spindles. (as you originally asked) :D and for you others out there with a 1978/79 620, you will need 17" or great diameter wheels to clear the drop spindles. Quote Link to comment

Now off to find spindles and hub! Quote Link to comment
Redd Posted April 21, 2007 Report Share Posted April 21, 2007 will you need to upgrade to the hardbody brake caliper as well? Quote Link to comment
]2eDeYe Posted April 21, 2007 Author Report Share Posted April 21, 2007 Yep vented rotors are required as well :D Quote Link to comment
spiffinspudater Posted April 21, 2007 Report Share Posted April 21, 2007 I think redeye posted this in the wrong section so I am quoting him here. 2eDeYe;6093']So in my search for hardbody front calipers I came across this cross reference list...

mklotz70 Posted April 21, 2007 Report Share Posted April 21, 2007 Redeye......the 620 disc hub will go onto the spindle...the bearings and depth are the same, but I don't remember if you can bolt the HB rotor onto the back of the 620 hub. I want to say yes, but I don't remember for sure. You cannot use the HB calipers with the 620 rotor, nor will the 620 calipers bolt onto the HB spindles. You can double check the rotor fit to the hub at the s/y. I have checked it before....just can't recall. I'm almost positive it will actually bolt on, but the real question is the distance between the wheel mounting surface and the rotor mounting surface on the back. If they're different between the two hubs, it will put the HB rotor in the wrong place for the HB caliper. I've got both, but I have to go back to work tonight(been off the last two weeks :) so I don't know when I'd be able to dig them out. You might try checking the hub part numbers on the two...if they match, question answered. If they don't, you'll have to check at the s/y cause it may have been a minor change that won't stop you. Anyway.... Quote Link to comment
]2eDeYe Posted April 21, 2007 Author Report Share Posted April 21, 2007 I'll just wait for my spindles and rotors come in and see if everthing bolts up...sure would be nice not to have buy bearings and hubs on top of everything else... Until then I guess the suspense will have to kill me :D Spiff, thanks for moving that. I put it there for those kingpin guys that are doing the swap as well, but it should be in this tread too :) Quote Link to comment
mklotz70 Posted April 21, 2007 Report Share Posted April 21, 2007 If you already have new bearings in your 620 hubs, they are the same as the HB bearings...so you can reuse them if you do need new hubs. Quote Link to comment
]2eDeYe Posted April 22, 2007 Author Report Share Posted April 22, 2007 Good to know, thanks Quote Link to comment
mklotz70 Posted April 27, 2007 Report Share Posted April 27, 2007 I did some comparing today. Still learning to use photobucket, but it's pretty dang cool. You can see that the center of the hub on the HB stuff(1st pic) is a bit different, but the dimensions of the hub itself are the same...and the spacing behind the rotors when mounted are the same as well. So.....yes, you can use HB rotors on 620 hubs. Quote Link to comment
]2eDeYe Posted April 27, 2007 Author Report Share Posted April 27, 2007 That rules, thanks Mike. Now if all my parts would come in, I could get to work on my front suspension. :D Quote Link to comment

Glengemen Posted May 4, 2007 Report Share Posted May 4, 2007 Hey Redeye, you going to cut your hubs for the Titans? Kinda like that? Quote Link to comment
]2eDeYe Posted May 4, 2007 Author Report Share Posted May 4, 2007 Great timing. I just got my drop spindles and calipers yesterday. I was gonna toss the old spindles in the vice and use my grinder to clearance the hubs. How did you machine yours? Did you use a brake lathe? I may go that route if so (I got a buddy that could toss them on the brake lathe at his work) Quote Link to comment
]2eDeYe Posted May 9, 2007 Author Report Share Posted May 9, 2007 come on Glen, spill how you machined your hubs :D Quote Link to comment
Glengemen Posted May 12, 2007 Report Share Posted May 12, 2007 sorry, have been retardedly busy, but yeah, I used an old school AMMCO machine to cut them. On the one I used I could remove one of the sides for cutting the 2 sides of the rotor. You might get away not getting this type of setup, but the newer machine I have at work wont do it without ripping half the thing apart. Also interesting note how uneven the hub/wheel mounting surface is to the centerline of the hub(which you cut almost perfectly on a lathe when chucked up by the bearing races). Maybe 2-3 degrees off. I guess that is the magic of a floatiing caliper though:) Quote Link to comment
]2eDeYe Posted May 12, 2007 Author Report Share Posted May 12, 2007 Awesome, thanks. I'll get ahold of my buddy and see if he can cut them :D Quote Link to comment
