steering rack

The steering rack and pinion couldn't be any simpler.  Its held to the front suspension crossmember by 4 bolts, the steering shaft u joint by one bolt and 2 tie rod ends.

I had to cut the multiple torn pieces of boots off and un clamp the boot clamps.
Take off the tie rod ends and before moving the lock nuts, measure how far in from the end they are so when it goes back together you will be in the ballpark.
The above picture shows the little copper drag cup (bottom most part near the red paint) that fits IN the adjustor plunger under the flat elliptical plate. Mine had almost NO oil in it, I'm sure that's why its so shiny on the bottom.
Mr. Twist  says when refilling the rack- to remove the thinnest shim under the flat plate to keep the desired drag on the rack. Im going to rebuild and try mine out before doing that.
The domed front cap has the steering shaft nutted through a roller bearing.  Mine needed a cleaning but looked in good shape.
The tie rods are held by a screw on cap and lock screw cap .  Just clean the internal mating surfaces and screw them back together where they aren't bound up. Make sure the little disk has the concave dimple facing out towards the tie rods.
Then re dimple the lock nut.
