Before starting just double check that you have the right length of driveshaft; 18.5 or 19.5 inch.
The driveshafts from CDD will be assembled, so that the components in the picture will be assembled onto the driveshafts and in the right position.
You will be reusing some of the old components, see list. Check for condition and renew if necessary.
The critical part of this process is the drive flange and the taper on the driveshaft. It is the flange / shaft taper that transmits the drive force, NOT the key / keyway. When dismantling the old shaft assembly check that the inside of the flange taper is clean bare metal, and the shaft taper is the same. Do a trial fit to check the taper engagement; engineers blue will be useful. (Blue the shaft and put the flange onto it, if all the blue disappears that indicates a good engagement so lightly tap the flange onto the shaft and try to turn it, if you can’t turn it then the taper is good, if you can then the flange will need to be lapped onto the shaft until the taper is good. Engineers Blue and lapping paste are necessary.
To make sure of a good taper engagement you could put the flange into an oven at 200o C for an hour.
Much of the fitting instructions for these shafts is exactly the same as in the Haynes Workshop Manual.
If you do not have a copy……..get one ! (Its content can not be reproduced here for copyright reasons)
This will guide you through the operations.
Use it to remove the old driveshafts from the car, and to remove the brakes and outer flanges, page 185 & 186.
Refer to page 183 section 3 to put the joint onto your diff flange and the flange assembly onto the new shaft
You do not have to do the ‘Driveshaft hub – overhaul’
When refitting the lower pivot bolt bushing is different; the bushes are already in the trunnion so it is assembled with the stainless steel bush into the trunnion bushes, no lube necessary, and the plastic washers each side; the width of the Vertical link does vary so use the washers to take up any slack. If more are put to the rear then this will slightly increase the toe in of the rear wheels (no bad thing !)
You must make sure that the UJs and the hubs are properly & adequately greased
When the shafts are both fitted a coating (spray, brush, wipe) of ACF50 will stop corrosion.
Follow the manual for all other operations
