nismopu Posted May 14, 2007 Report Share Posted May 14, 2007 does 521 stuff swap over to pre 78 620 suspension? A buddy of mine has some custom brakes and hubs for a 521, including a locked rear end. I was wondering if it would just swap over or if any mods were needed? peace. Quote Link to comment

]2eDeYe Posted May 15, 2007 Report Share Posted May 15, 2007 I know 620 stuff will bolt up to a 521 and that the inner (I think it's the inner) 521 bearing is a pain to find. Anyway you can just swap the brake stuff to the 620 spindle? Quote Link to comment
datzenmike Posted May 16, 2007 Report Share Posted May 16, 2007 Just yank the axles and unbolt the center section and switch. Is the rear end a limited slip or a 'welded up' locked. If LSD get it, if its welded, pass on it unless you only drive in the mud. The Ls didn't make enough to need LSD but wouldn't hurt for off road. Quote Link to comment
Icehouse Posted May 16, 2007 Report Share Posted May 16, 2007 The 78 is much wider than the 521 well the suspension anyways. Me and Ted measured the leaf mounting points and they are off by a little bit. Quote Link to comment
BEEBANI Posted May 16, 2007 Report Share Posted May 16, 2007 I noticed the Leary plug.........how are you feeling? reminds me of the cheech and chong movie that Mr. Leary made a cameo in. Anybody old enough to remember that? Quote Link to comment
71-521 Posted May 16, 2007 Report Share Posted May 16, 2007 yup... I have all their movies... but that was a different time and altitude! Quote Link to comment

Anyway you can just swap the brake stuff to the 620 spindle? there is a 2 mil diffrence in the spindle's... 521 vs 620 look at about page 5 of the NWDE Disc Brakes On A Kingpin Truck Thread if you need more info. I had to end up getting my inners from a dude in Australia.. Good Luck with the Bearings....just keep it all together, and bolt up the whole enchillada.. Quote Link to comment
