Greg,
I don't know if there is an industry standard, but in general, I imagine
typical rebuilders try to bring a rebuildable unit back up to a minimum of
65-75%.
Otherwise they'd have to use too many brand new parts.
Since there are NO new STOCK racks and NO new STOCK pinions available for
TR4-6 range (that I know of) 'brand new' is not even an option here. Only 'used
parts' from stripped cores are typically used.
You can trust a rebuilder based on their reputation or you can rebuild your's
yourself or you can buy a brand new aftermarket substitute.
Asking a rebuilder what is replaced/renewed is a tough question - especially
if typically, like on these steering racks, nothing might be replaced or
renewed but simply checked, readjusted, painted, and lubed. And if something is
replaced, it is likely replaced with an already used part. Any vendor will have
a
hard time describing 'how used' the particular parts in any one rebuilt unit
are.
If you want the highest quality I believe it will cost you 3 times the cur
rent market rate. (time finding NOS or NLA parts, paying for these parts, and
time doing the rebuild yourself)
Or you (or a rebuilder of your choice) could find nothing inside your rack
needs replacement but simply an adjustment of the shims to regain compliance
with original factory specs.
Good luck,
Carl

the steering rack rebuild is a critical aspect of my suspension renewal and I
want to
ensure that it is rebuilt to the highest standards.
