The output shaft seals on my car are weeping although there doesn't seem to be any play or noise at the bearings.
After 100k miles is it worth just changing the seals or should I do the bearings at the same time?
I see Classic Parts do a kit for this, with the crush spacer et al, but the bearings would add another £150ish to the job, and if not neccesary I would rather avoid it. Even though my car has outboard brakes I really don't want to strip it down twice!
Any insight greatly apprieciated.

I think you already know the answer to your question, I suppose if you strip the assembly down you could replace the bearings if they show damage or wear, but if you get it wrong you will have to do it again.
I replaced the bearings and seals on my Pre He some years ago. I was spared your painful decision, as one of the bearings had collapsed. I took the view that if one side had failed the other side probably needed replacement.
I also replaced the diff input seal. and although I did not fit a new crush assy it worked out OK.

Well I finally took a day off work to do this so I thought I would report back.
Lesson #1 REMOVE THE SUBFRAME!
I didn't and EVERY bolt was a struggle to access.
The bottom bolt had to come out of the hub carrier to give enough movement in the driveshaft to undo the bolts to the output shaft 1/12th of a turn at a time!
Without inboard brakes I thought I would have an easy time after that but in their infinite wisdom Jaguar decided to put the handbrake cable reaction plate using the old caliper mounting bolts so they had to be undone with all the fun that entails.
Lesson #2 Once the output shaft assy has been dismantled, EVERYTHING has to be replaced.
This is because the seal does not pass over the bearings, and the is no way to remove the outer bearing without destrying it (even with a press). The crush spacer and lock tab are obviously consumable. Luckily, despite being miserly, I had splashed out and had it all.
Finally 16mm IS NOT 5/8, despite what my freindly mechanic said when I bought the parts. As I left he said in a sarcastic tone "Have fun". I did'nt think anything of it at the time, but he KNEW!..... GRRRRR!
