now then, only ever done the fronts myself, but i am
thinking the only real difference is the hand brake?
Would that be the case? Anyone?

  If so there are guides on both on here somewhere
Although i cant remember seeing one for hand brake
Shoes etc. Hmm.

But no i would not say it was to difficult tbh. No special
Tools. Just make sure you clean and centre the disc on
 the hub With the wheel nuts first, then do up the disc mounting
Bolt then remove the nuts and fit the wheel. Other
Wise the you can get judder on the brakes.

the bearings have to be pressed into the hubs.  You also need a press to remove them. Unlike the fronts on the omega, you don't replace the hub, and its not a combined 1-piece hub/bearing...

I have replaced lots of rear wheel bearings on Monzas (although not on Omegas -I've just checked the EPC though and can see that the design is basically the same).  Those on the Senator B, Carlton Mk 3 and Omega are similar to the Monza/Senator A, inasmuch as the wheel hub/stub axle passes through the bearing, then an inner drive flange is pressed on over splines and secured with a large nut done up to a very high torque. You need the correct purpose-made pullers and presses to do the job. If you don't have these, or an ingenious way of adapting existing pullers/presses, don't even think about it. If you have access to an engineering workshop or commercial garage and a collection of assorted  tools, pullers, presses etc that can be adapted, it is possible to do the job with the trailing arm off the car. For an amateur mechanic on a suburban driveway, trying to do it on the car, and with only basic tools, it is next to impossible.

Well I have done the home mechanic bit and changed a rear wheel baring in the drive but it is not easy.  

I used a cheap electric impact wrench to undo the inner nut and a stanard puller to remove the outer bell housing.  Pressed the out baring out using a socket that just fitted over the baring.  I then rigged up a makshift puller with some threaded rod and 1/4" bar.  Threaded the rods throught the backplate mounting holes and wound it it out.  Reversed the process to press the new baring in.  

This was a long and difficult job but most of it was working out how to do it.  It takes a fair bit of pressure - the threaded rod only just held up and the 1/4" bar bent like butter but eventually held enough to do the job.

Good luck. ;)

  You also need a very big Torque wrench as the setting is quite high :o.

Hi,
Yes, it is possible to change rear wheel bearings, but without a bearing press you have to have a decent puller set available and lots of high tensile studding and bits and pieces plus a socket to fit the big nut, and a fair bit of ingenuity. If you are a 7st weakling !!! then I would say it's a no no

Ah yes - the difference between possible and advisable!

I think I have opted for not advisable
