Great write-up and contributions everyone. This was exactly what I was looking for so I could D-I-M on my 98 BD GT which has the same shifter-slop issue. This is on a SoCal Sube with 77K on it so presume that the heat/dryness (and stop-and-go traffic) just decimated the stock bushings. Think I'll go with the 3/4" long flanged sleeve bearings in MDS-filled nylon for longevity and good wear resistance.
It's been so long since I futzed with the tranny on any of my Subes that I can't seem to get my mind around why it can't be disassembled and then R&R'd off-car. Remind my aged brain why I can't just put my 98 BD up on a lift, support the tranny with a high-lift tranny jack in order to remove the transmission cross-member, then take the entire shift linkage assembly off the car and then to a work bench to R&R it.
Plan to do this at the base auto hobby shop at the same time I fix the clutch slave issue. Going to do the TSB 03-52-03
repair to the clutch hose and slave cylinder to fix the sticking clutch issue, and replace the master cylinder at the same time so expect this to be at least a half-day event.
Will post-up any recommendations and pics I come across that might help.
