997 drive shafts

I have successfully changed:

Front n/s lower control arm
Front anti-roll bar bushes
Did both condensers, dryer/receiver and got the system charged locally.
Also fitted Zunsport grilles to hopefully prolong the life of them and reduce build up of matter.
I spent 2 days. Yes 2 days!! sorting out the exhaust system. The long 140mm bolt on the silencer was sheared and there was this little, niggling rattle.

What a nightmare. So I thought sod it, i'll change all the bolts on the exhaust system to SS. Sheared 4 of the 6 bolts on the silencer brackets and one bolt on the rear of the n's exhaust manifold. (and I thought my 944 was a pig for this).
Tapped it out successfully (and fortunately), replaced the exhaust manifold gaskets, and the 3 bolt flange gaskets. Job done.
I had even covered the lot in de-blocker overnight.
Porsche main dealer wanted £7.42 per little brillo pad damper, plus VAT and could not source me the ss bolt sleeve/spacers. Thanks to 9 apart - 8 dampers, 4 sleeves incl. VAT and carriage £50.

Anyway, i'm rambling. Is there a thread on here with a step by step procedure on removing a rear (Carrera 2) driveshaft?
Has anyone re-built one (DIY)?

Cheers
Rob

Never done 997 drive shafts but done plenty of others. The bolts for the driveshafts are stretch bolts & Porsche advise should not be reused. I've know a few break so I'd agree to buy new ones. Also use a torque wrench to retighten. Use a good quality bit for the bolts (normally XZN 12 point) and clean the heads first.
Check bits are available. I know Boxster ones are not fully spared. I think gaiters are available but not CV joints, but its worth repacking them. It is a filthy horrible job. Multiple cans of brake cleaner to wash it out, plastic gloves otherwise you'll be leaving black fingerprints for weeks. Don't under estimate how much grease you'll need to repack them I think I used 2 x 500mls pot on 4 driveshafts (8 x CVs). The circlips can be pigs to remove, but 997 ones may not be able to dismantled.

Thanks Jim.
It's the outer boot that has a slit in the rubber. The current seepage of grease is minimal but I don't suspect it will stay that way.

Quick look it appears the 996/997/986 boots are all the same
