I have some slop and rattle in my son's new (98obs) car. The lock bolt right on the shaft (inside the boot) was a little too loose, tightened that, took care of some of the slop, most of the rattle. I had some one shift thru the gears while I was under the car. Every bushing was toast. So I ordered them all, cheap fix for an annoying issue.
2 Subaru shaft (under the boot) bushings. (not available from KB)
2 KB linkage Bushings
1 KB back bushing
1 Subaru linkage knuckle (not available from KB)
1 Subaru linkage/knuckle bolt (yours is probably re-useable)
1 Subaru knuckle roll pin. (yours is probably re-useable)
I suspect that will take care of everything else. Haven't installed it yet, Tuesday for sure.
