thought I'd revive this one with an update - swivel hub rebuild completed, MASSIVE THANKS to MUDRUNNER, without his run down I'd still be scratching my head in places. Also a big thanks for the manual from this site, total gold.
All seals and bearings replaced, new tie rod end, new brakes (and pending rebuild next service on the front calipers) turbo rebuilt (bit of a story there!) big visual inspection and torques checked on bolts etc.
All that is left is the rear brakes and diff oil, then coolant flush. Timing chain - after looking at the manual, can go take a long walk off a short pier!
So, all that is left is to test her out and see if my handy work lasts another 300,000!
