on to the suspension v2

The lower control arm bushings were visbly cracking before taking the parts apart.  Spray everything with PB blaster before starting this.  Loosen all nuts before taking individual parts off.

The lcas were wallered out.  The lower trunnion pivot bushings welded themselves to the bolt, wrecking the lcas.  Out comes the sawzall.



Removing the shock was an experience.
The gurus in the mg experience said to remove the upper shock bolts and there is "very little left in the coil spring.'
Well, I put a strap around the lca and the frame, removed the bolts, and when loosening the strap the arm kicked down about 4".  Coils have a lot of power in them...
There are LCAs with a negative caster that supposedly help handling. But also reduce normal driving precision on the street....I'll try stock first.
The kingpins were in good shape , still has some grease on them, the bearings we're smooth but are getting replaced anyway.  All parts got degreaser, cleaned, and electrolytic de rusting.  Just waiting on parts..


When dismantling parts, try to keep the bolts that go with that part together. Screw the nut and locknut back onto that part to keep from losing it.
 Note that the sway bar connections are
left and right handed and cannot be interchanged along with their LCArms.....

 


The kingpin isn't as complicated as it seems. Just a lot of cleaning old grease.
 
 I already forgot to add the bearing spacer (part 34) to the hub I re did, so I had to re-pull the inner bearing seal to
 install this.
According to Mr Twist, It makes the spindle act like its thicker than it is..

The only thing that will probably change on the hub is the bearing shims. (part 35) 
When reassembling the hub with new bearings, the shims keep proper tension between the bearings

My kingpin and trunnion bronze bushings were in very good shape- still were round, and still had the "leaf" pattern for distributing grease across the surface.  When reassembling, I pregreased all bushings and anti seized the lower trunnion bolt and all threaded parts.
All suspension is getting poly bushings
