Thanks for the helpful responses to my query. I of course was hoping you would say it was OK as is. However knowing the poor life history of these bearings, even those set to factory specs; it is probably in my best interest to tighten it more. After seeing what kind of force was involved I realize I do not have the proper equipment to hold the shaft safely and the wrench I thought would work definitely would not have done the job. That is why I opted to take it to a Saab shop in the first place. Too bad it did not work out. I will of course verify that the preload is too low before proceeding. I thought I might simply be able to heat up the nut and tighten it more. However it sounds like it is better to start from scratch.
I checked the pinion depth and it appears to be exactly where it was before I took it apart which is good news. However on the subject of stack height I measured it last night and I came up with 7.717 in. Before I replaced the old sloppy bearings I also had a similiar stack hieght readings. The book specification is supposed to be between 7.677 - 7.681 in. I have repeatly checked this and always come up with a larger number. No matter how much I hope otherwise or question my technique. I have verified my caliper's accuracy. If I understand it correctly the shims are usually added to put you within the specified range. Therefore I am out of spec already and additionally have two shims .016"(.4mm); .020(.5mm) which came out originally. Could it have come out of the factory that far out of spec and run 150,000 miles and actually shifted OK? Is mine the only wacky Saab transmission? I am 3rd owner of car and have many records. I do not think tranny was ever opened before. What would you suggest for reassembly? No shims to get as close as I can to specs? I knew a transmission overhaul would be a chore however I did not think I would run into these issues.
