Preload on pinion bearing? (for snowmobile) 200

To all and especially Snowmobile.

You mentioned in your answer in my earlier post conerning a vibration in my drive shaft after changing all u-joints, bearing and pinion seal, that I should have preloaded the pinion.

I have never done this before...what I did was to use a puller to take off the flange, pulled out the old seal, put in new (tapped in with wooden block behind reversed flange) seal. I then torqued the nut on the flange to draw it down on the splined shaft. Final torque was at 160 lbs, would this preload the pinion?

I am going to follow your advice S'mobile, I have a lift in an enclosed building
to use. Do you think I should replace the tranny mount? I have jacked the tranny up a couple times with the present mount, though it looks very good yet.
Do you think I should open the rubber donut again and make sure it is set so the driveshaft is level as it goes through it? Check it with a level too. No balance plates have come off this shaft. Do you really feel the backwards bolt by the zirt could have a bearing? I could also re-torque to spec. all the flange bolts, is that critical?
