Here's where it all starts:
.
.
Poly bushings are garbage, they crumble....
.
.
So after disassembly and some quality time with the sandblaster we can see how awesome the GM welders got splatter everywhere....
.
.
.
.
After welding up the arm and improve GM's welds and some time with a flapper sanding disc we are here:
.
.
.
Now the overlapping sheetmetal at the end of the arms get welded up:
.
.
.
more parts blasted.....
.
.
.
All parts get three coats epoxy "Chassis Saver" then ready for re-assembly.... set up on the setup tool (old spindle that was polished down to allow slipping the bearings on and off):
.
.
.
.
Timken bearings:
.
.
.
With the flange nut torqued you want .001-.002" max endplay with oil only, no grease...
.
select shims to get it to .0015" endplay....
.
.
.
.
then continue assembly with new backing plate and parking brake shoes as well as SS PB hardware...
.
.
.
I thread the spindles 3/8X24 UNF and countersink the rotor holes - that way the rotors can be bolted to the spindle instead of riveted. Photos show the bolts/rotors after the spindle was already pressed in...
.
.
.
compression tool for front trailing arm bushings:
.
.
.
New front bushing installed, I only use rubber for obvious reasons....
.
finished ...
