not to hand mate but it is easy job!!
1)loosen rear wheel nuts, jack up car and support on axle stands
2)open the bonnet and unscrew the cap on the brake fluid bottle, make sure the handbake isnt engaged, remove rear wheel.
3)undo the caliper bolts (13mm socket required) from the caliper carrier and keep safe, you may have to wiggle it too move the  piston back slightly so you can pull it off the disc along with the pads. i usually support the caliper on some bricks etc so as not to put strain on the brake pipe/handbrake cable.
4)Now you have to remove the caliper carrier bracket, these can be b'stards to say the least, make sure the allen bolt head is clean and free of rust and crap, then get a 8mm allenkey and try and undo. hopefully with a bit of force they will come undone if not heat/other methods may have to be used. Once removed keep safe along with the bolts.
5)now knock the dust cap from the center of the hub (it will come off with i light tap, or use a screw driver), wipe any grease from the nut/pin etc so you can see what your doing.
6)straighten the split pin so you can pull it from the axle, then remove the locking 'crown' and nut (24mm socket i think cant remember), there is also a washer behind the nut (probably hiding in grease!) remove this also and keep it safe with the other bits.
7)you should now be able to remove the rear disc, the bearing are in 2 halves (inner/outer)the inners will fall away (youll need to remove an oil seal from back of the disc if it hasnt come away already by this time)but the outers will be firmly in place in the disc. if an inner is stuck on the shaft you may need to persuede it with a drift or pulling tool but normally they come of easy.
8)if you have access to decent pulling tools now is the time to use them as it makes the job easier, use a expanding collet puller with a slide hammer and the outers are easy to remove, if not youll have to use a drift/punch to knock them out.
9) clean up your disc, and get the new bearings from there boxes, if you have a press and relevant tooling use these to push the new bearing outers into the disc, repeat this for both outers.
10)pack the center section of the disc with the outers in with fresh grease, then get the inner for the back bearing and cover in grease also, then slot it facing taper in, into the outer of the baearing in the back of the disc. now refit the oil/grease seal (fit new if you have)
11) now slide the disc onto the axle and push it all they way back (ensuring the axle is clean from crap/old grease etc), smear the other inner bearing in grease and slide this onto the axle (taper going in) and push it into the grease filled outer at the front of the disc,
12)clean and refit the washer, then refit the nut and tighten by hand, theres 2 ways of doing the next bit either you know it or you do it by the book (torque settings) but bearings are never the same so spin the disc whilst tightening, dont tighten too much as to make the disc slow down and hardly move but you need to comprimise between any movement on the shaft (too loose) but you dont want it too tight as too stop it/cause to much friction when turning. youll get the general i dea as you do it.
13)fit the locking crown on in a position so one of the gaps aligns with the pin hole in the axle, now using a new split pin slide it into the hole and bend the ends up and around once in postion.
14)smear some grease over the top of all this and put some in the dust cap and tap it bacck on firmly.
there you have it, then simply refit the carrier and caliper in the reverse of how you removed them, its often wise to fir new bolts if you have damaged any whilst removing as it will only hamper the job when it needs doing again.
now is also a good time to be changing the discs and pads whilst in this position as you dont have to waste time knocking old bearing out of discs etc, you could have new ones prepared ready to go on which would cut the job time down no end!! also if thinking of painting your calipers now is a good time also.
have done this so many times its that easy, but ive prob forgot some thing! sorry i couldnt help with pics/haynes manual but its the best i can do at the mo!!
