Hm, never noticed that, but I do put those back in the way I found 'em. Check. > To separate drive shaft (half axle another name) from CV joint there is > a circlip. Ah, so it's not like the 95/96/97 with the groove in the shaft and the snapring.

Well, I'm also OK with 200 pounds of me, at a foot from the nut on the wrench acting as a torque wrench. But pretty sure I've got one that goes that high. I also have a calibrated kid who would be just right on the end of a 3' pipe. > Having done many boots ... eventually I came to the conclusion (when I > got a new (it was only 10-12 yo at the time) 900, it had SAAB boots. > The after market replacements I fitted did not last the 6 or so years I > had the car. > > Go on replace just the boot. Once you done it a few times it is easy. Great, thanks for your time! Dave
